Introduction

FamilySearch GEDCOM 7.0 was released in 2021 as the latest version of the GEDCOM format for the transmission and storage of genealogical information. GEDCOM was developed by the Family History Department of The Church of Jesus Christ of Latter-day Saints to provide a flexible, uniform format for exchanging computerized genealogical data. Its first purpose is to foster sharing genealogical information and to develop a wide range of inter-operable software products to assist genealogists, historians, and other researchers. Its second purpose is as a long-term storage format for preserving genealogical information in an open, standard format that will be accessible and understood by future genealogists and the systems they use.

“GEDCOM” is an acronym for GEnealogical Data COMmunication and is traditionally pronounced “ˈdʒɛdkɑm.”

Purpose and Content of The FamilySearch GEDCOM Specification

The FamilySearch GEDCOM Specification is a technical document written for computer programmers, system developers, and technology-aware users. This document describes a document and file format as follows:

Chapter 1 describes a hierarchical container format. This container format is a general-purpose data representation language for representing any kind of structured information in a sequential medium, similar to XML, JSON, YAML, or SDLang. Chapter 1 discusses the syntax and identification of structured information in general, but it does not deal with the semantic content of any particular kind of data.

Chapter 2 describes several data types used to represent genealogical information, such as a date format that permits dating in multiple calendar systems.

Chapter 3 describes a set of nested genealogical structures for representing historical claims, such as individuals, families, and events; sourcing information, such as sources, repositories, and citations; and research metadata, such as information about researchers and rights.

A set of structures conforming to the first 3 chapters of The FamilySearch GEDCOM Specification is called a FamilySearch GEDCOM dataset. A string of octets encoding a dataset is called a data stream.

Chapter 4 describes a file format for bundling a dataset with a set of media files or other supporting documents.

Prior to 7.0:

Purpose for Version 7.x

There have been multiple prior releases of this specifciation, with somewhat idiosyncratic version numbering. The first public comment draft was released in 1984. The previous major version was 5.5.1 which was released in draft status in November 1999 and re-released as a standard in October 2019.

Version 7.0 has a number of goals, including

Version 7.0 introduces several breaking changes with version 5.5.1; 5.5.1 files are, in general, not valid 7.0 files and vice versa. These breaking changes were necessary to remove complicated constructs left over from earlier versions. For a complete list of changes, see the accompanying changelog.

A Guide to Version Numbers

Starting with version 7.0.0, version numbers use semantic versioning. The 3 numbers are titled major.minor.patch.

A new major version may make arbitrary changes to the specification. Distinct major versions are not in general either forward or backward compatible with one another.

A new minor version will preserve the validity of data from all previous minor versions. It may make additional data valid, for example by adding new structure types, allowing current structures in new contexts, or adding new enumerated values or calendars. A minor release will not change the semantic meaning of data from previous minor releases, so for example a 7.0 document is also a valid 7.1 document and represents the same information in both.

A new patch version is a clarified or improved specification for the same data and introduces no changes in the data itself. Any software that correctly implements X.Y.Z also correctly implements X.Y.W. If there is an ambiguity or contradiction in the specification, it will be resolved in a patch version unless it is known that implementations interpreted the spec differently and that clarifying the intended meaning would cause incompatibilities between those implementations.

It is recommended that implementations accept all data at their own or a lesser minor version, regardless of the patch version. It is also recommended that they import data from subsequent minor versions by treating any unexpected structures, enumerations, or calendars as if they were extensions.

URIs and Prefix Notation

This document defines Uniform Resource Identifiers (URIs) to unambiguously identify various concepts, including structure types, data types, calendars, enumerated values, and so on. In a few places, existing URIs defined by other bodies are used, following the best practice that a new URI should not be introduced for a concept for which a URI is known.

Rather than write out URIs in full, we use prefix notation: any URI beginning with 1 of the following short prefixes followed by a colon is shorthand for a URI beginning with the corresponding URI prefix

Short PrefixURI Prefix
g7https://gedcom.io/terms/v7/
xsdhttp://www.w3.org/2001/XMLSchema#
dcathttp://www.w3.org/ns/dcat#

When the specification says xsd:string, it means http://www.w3.org/2001/XMLSchema#string. This is a specification shorthand only; the string “xsd:string” is not the URI defining this concept, http://www.w3.org/2001/XMLSchema#string is.

1 Hierarchical container format

1.1 Characters

Each data stream is a sequence of octets or bytes. The octets encode a sequence of characters according to the UTF-8 character encoding as described in §10.2 of ISO/IEC 10646:2020.

Previous versions allowed multiple character encodings, defaulting to ANSEL. 7.0 only uses the UTF-8 character encoding.

A file containing a FamilySearch GEDCOM data stream should use the filename extension .ged.

The first character in each data stream should be U+FEFF, the byte-order mark. If present, this initial character has no meaning within this specification but serves to indicate to other systems that the file uses the UTF-8 character encoding.

Certain characters must not appear anywhere within a data stream:

Implementations should be aware that bytes per character and characters per glyph are both variable when using UTF-8. Use of Unicode-aware processing and display libraries is recommended.

Character-level grammars are specified in this document using Augmented Bakaus-Naur Form (ABNF) as defined in STD 68 (https://www.rfc-editor.org/info/std68) and modified in RFC 7405 (https://www.rfc-editor.org/info/rfc7405). We use the term “production” to refer to an ABNF rule, supported by any other rules it references.

The following is a brief summary of the parts of ABNF, as defined by STD 68 and RFC 7405, that are used in this document:

The banned characters can be expressed in ABNF as production banned:

banned = %x00-08 / %x0B-0C / %x0E-1F ; C0 other than LF CR and Tab
       / %x7F                        ; DEL
       / %x80-9F                     ; C1
       / %xD800-DFFF                 ; Surrogates
       / %xFFFE-FFFF                 ; invalid
; All other rules assume the absence of any banned characters

All other ABNF expressions in this document assume the absence of any characters matching production banned.

This document additionally makes use of the following named character sets in ABNF:

digit       = %x30-39   ; 0 through 9
nonzero     = %x31-39   ; 1 through 9
ucletter    = %x41-5A   ; A through Z
underscore  = %x5F      ; _
atsign      = %x40      ; @

1.2 Structures

A structure consists of a structure type, an optional payload, and a collection of substructures. The payload is a value expressed as a string using 1 of several data types, as described in Chapter 2.

Every structure is either a record, meaning it is not contained in any other structure’s collection of substructures, or it is a substructure of exactly 1 other structure. The other structure is called its superstructure. Each substructure either refines the meaning of its superstructure, provides metadata about its superstructure, or introduces new data that is closely related to its superstructure.

The collection of substructures is partially ordered. Substructures with the same structure type are in a fixed order, but substructures with different structure types may be reordered. The order of substructures of a single type indicates user preference, with the first substructure being the most-preferred value, unless a different meaning is explicitly indicated in the structure’s definition.

A structure must have either a non-empty payload or at least 1 substructure. Empty payloads and missing payloads are considered equivalent. The remainder of this document uses “payload” as shorthand for “non-empty payload”.

Unlike structures, pseudo-structures needn’t have either payloads or substructures. TRLR never has either, and CONT doesn’t when payloads contain empty lines.

A structure is a representation of data about its subject. Examples include the entity, event, claim, or activity that the structure describes.

Datasets also contain 3 types of pseudo-structures:

Previous versions limited the number of characters that could appear in a structure, record, and payload. Those restrictions were removed in 7.0.

1.3 Lines

A line is a string representation of (part of) a structure. A line consists of a level, optional cross-reference identifier, tag, optional line value, and line terminator. It matches the production Line:

Line    = Level D [Xref D] Tag [D LineVal] EOL

Level   = "0" / nonzero *digit
D       = %x20                            ; space
Xref    = atsign 1*tagchar atsign         ; but not "@VOID@"
Tag     = stdTag / extTag
LineVal = pointer / lineStr
EOL     = %x0D [%x0A] / %x0A              ; CR-LF, CR, or LF

stdTag  = ucletter *tagchar
extTag  = underscore 1*tagchar
tagchar = ucletter / digit / underscore

pointer = voidPtr / Xref
voidPtr = %s"@VOID@"

nonAt   = %x09 / %x20-3F / %x41-10FFFF    ; non-EOL, non-@
nonEOL  = %x09 / %x20-10FFFF              ; non-EOL
lineStr = (nonAt / atsign atsign) *nonEOL ; leading @ doubled

The level matches production Level and is used to encode substructure relationships. Any line with level 0 encodes a record or a record-like pseudo-structure. Any line with level x > 0 encodes a substructure of the structure encoded by the nearest preceding line with level x − 1.

Previous versions allowed spaces and blank lines to precede the level of a line. That permission was removed from 7.0 to simplify parsing.

The cross-reference identifier matches production Xref (but not voidPtr) and indicates that this is a structure to which pointer-type payloads may point. Each cross-reference identifier must be unique within a given data document. Cross-reference identifiers are not retained between data streams and should not be made visible to the user to avoid them referring to transient data within notes or other durable data.

Each record to which other structures point must have a cross-reference identifier. A record to which no structures point may have a cross-reference identifier, but does not need to have one. A substructure or pseudo-structure must not have a cross-reference identifier.

The tag matches production Tag and encodes the structure’s type. Tags that match the production stdTag are defined in this document. Tags that match extTag are defined according to Extensions.

The line value matches production LineVal and encodes the structure’s payload. Line value content is sufficient to distinguish between pointers and line strings. Pointers are encoded as the cross-reference identifier of the pointed-to structure. Each non-pointer payload may be encoded in 1 or more line strings (line continuations encode multi-line payloads in several line strings). The exact encoding of non-pointer payloads is dependent on the datatype of the payload, as determined by the structure type. The datatype of non-pointer payloads cannot be fully determined by line value content alone.

If a line value matches production Xref, the same value must occur as the cross-reference identifier of a structure within the document. The special voidPtr production is provided to encode null pointers.

If the first character of the string stored in a line string is U+0040 (@), the line string must escape that character by doubling that @.

Previous versions required doubling all @ in a line value, but such doubling was not widely implemented in practice. @ is only doubled in this version if it is the first character of a line string.

A structure with tag NOTE, level 1, and a 2-line payload where the first line is “me@example.com is my email” and the second line is “@me and @I are my social media handles” would be encoded as

1 NOTE me@example.com is my email
2 CONT @@me and @I are my social media handles

Line values that match neither Xref nor lineStr are prohibited. They have been used in previous versions (for example, a line value beginning @#D was a date in versions 4.0 through 5.5.1) and may be used again in a future version if an appropriate need arises.

The components of a line are each separated by a single delimiter matching production D. A delimiter is always a single space character (U+0020). Using multiple delimiters between components of a line is prohibited. Thus if the tag is followed by 2 spaces, the first space is a delimiter and the second space is part of the line value.

All characters in a payload must be preserved in the corresponding line value, including preserving any leading or trailing spaces.

Each line is ended by a line terminator matching production EOL. A line terminator may be a carriage return U+000D, line feed U+000A, or a carriage return followed by a line feed. The same line terminator should be used on every line of a given document.

Line values cannot contain internal line terminators, but some payloads can. If a payload contains a line terminator, the payload is split on the line terminators into several payloads. The first of these split payloads is encoded as the line value of the structure’s line, and each subsequent split payload is encoded as the line value of a line continuation pseudo-structure of the structure. The tag of a line continuation pseudo-structure is CONT. The order of the line continuation pseudo-structures matches the order of the lines of text in the payload.

Line continuation pseudo-structures are not considered to be structures nor to be part of a structure’s collection of substructures. They must appear immediately following the line whose payload they are encoding and before any other line.

Because line terminators in payloads are encoded using line continuations, it is not possible to distinguish between U+000D and U+000A in payloads.

Previous versions limited the number of characters that could appear in a tag, cross-reference identifier, and line-value. Those restrictions were removed in version 7.0. The CONC pseudo-structure, which allowed line values to have a shorter length restriction than payloads, was also removed.

The following are examples of valid but unrelated lines:

1.4 The Header and Trailer

Every dataset must begin with a header pseudo-structure and end with a trailer pseudo-structure.

The trailer pseudo-structure has level 0, tag TRLR and no line value or substructures. The trailer has no semantic meaning; it is present only to mark the end of the dataset.

The header pseudo-structure has level 0, tag HEAD, and no line value. The substructures of the header pseudo-structure provide metadata about the entire dataset. Some of those substructures are defined here; others are defined in Chapter 3 or by extensions.

Every header must contain a substructure with a known tag that identifies the specification to which the dataset complies. For FamilySearch GEDCOM 7.0, this is the GEDC structure described in Chapter 3.

A header should contain an extension schema structure with tag SCHMA as described in Extensions.

1.5 Extensions

A standard structure is a structure whose type, tag, meaning, superstructure, and cardinality within the superstructure are described in this document. This includes records such as INDI and substructures such as INDI.NAME.

Two forms of extension structures are permitted:

Extension structures may have substructures, which may be either tagged extension structures of extended-use standard structures.

All other non-standard structures are prohibited. Examples of prohibited structures include, but are not limited to,

In some cases, an extension may need to allow multiple structures where this document allows only 1. The recommended way to do this is to create an extension tag and URI and serve a page describing how the semantics of the structure have been extended to allow multiple instances.

Suppose I have multiple sources that give different ages of the wife at a wedding; however, this specification allows only 1 MARR.WIFE.AGE. An extension could not include multiple MARR.WIFE nor MARR.WIFE.AGE, but could define a new extension _AGE, give it a URL, and provide the following definition of this extension structure type at that URL:

Alternate age: an age attested by some source, but not accepted by the researcher as the actual age of the individual. If the age is accepted by the researcher, the standard tag AGE should be used instead.

This alternate age extension structure could be used as follows:

1 MARR
2 WIFE
3 AGE 27y
3 _AGE 22y

Enumerated values may be extended with new values that match production extTag. Enumerations may not use standard values from other enumeration sets.

The following is not allowed because PARENT is defined as a value for ROLE, not for RESN

0 @BAD@ INDI
1 RESN PARENT
1 NOTE The above enumeration value is not allowed

Dates may be extended provided they use a calendar that matches production extTag. Dates with extension calendars may also use extension months and epochs.

1.5.1 Extension Tags

Each use of the extTag production is called an extension tag, including when used as a tag, calendar, month, epoch, or enumerated value. Each extTag is either a documented extension tag or an undocumented extension tag. It is recommended that documented extension tags be used instead of undocumented extension tags wherever possible.

A documented extension tag is a tag that is mapped to a URI using the schema structure. The schema structure is a substructure of the header with tag SCHMA. It should appear within the document before any extension tags. The schema’s substructures are tag definitions.

A tag definition is a structure with tag TAG. Its payload is an extension tag, a space, and a URI and defines that extension tag to be an abbreviation for that URI within the current document.

The following header

0 HEAD
1 SCHMA
2 TAG _SKYPEID http://xmlns.com/foaf/0.1/skypeID
2 TAG _MEMBER http://xmlns.com/foaf/0.1/member

defines the following tags

TagMeans
_SKYPEIDhttp://xmlns.com/foaf/0.1/skypeID
_MEMBERhttp://xmlns.com/foaf/0.1/member

The meaning of a documented extension tag is identified by its URI, not its tag. Documented extension tags can be changed freely by modifying the schema, though it is recommended that documented extension tags not be changed. However, a tag change may be necessary if a product picks the same tags for URIs that another product uses for different URIs.

The following 2 document fragments are semantically equivalent and a system importing one may export it as the other without change of meaning.

0 HEAD
1 SCHMA
2 TAG _SKYPEID http://xmlns.com/foaf/0.1/skypeID
0 @I0@ INDI
1 _SKYPEID example.person
0 HEAD
1 SCHMA
2 TAG _SI http://xmlns.com/foaf/0.1/skypeID
0 @I0@ INDI
1 _SI example.person

An extension tag that is not given a URI in the schema structure is called an undocumented extension tag. The meaning of an undocumented extension tag is identified by its tag.

1.5.2 Requirements and Recommendations

Future versions may include additional recommendations relating to documentation, machine-readable documentation, or embedded metadata about extensions within the schema.

1.5.3 Extension versus Standard

Standard structures take priority over extensions. Data contained in extension tags will not be interpreted by other systems correctly unless the other system supports that particular extension. In particular, those supporting extensions should keep in mind the following:

1.6 Removing data

There may be situations where data needs to be removed from a dataset, such as when a user requests its deletion or marks it as confidential and not for export.

In general, removed data should result in removed structures.

Pointers to a removed structure should be replaced with voidPtrs.

If removal of a structure makes the superstructure invalid because the superstructure required the substructure, the structure should instead be retained and have its payload changed to a voidPtr if a pointer, or to a datatype-appropriate empty value if a non-pointer.

If removing a structure leaves its superstructure with no payload and no substructures, the superstructure should also be removed.

2 Data types

Every line value (with any continuation pseudo-structures) is a string. However, those strings can encode 1 of several conceptual datatypes.

2.1 Text

A free-text string is text in a human language. Conceptually, it may be either a user-generated string or a source-generated string. Programmatically, both are treated as unconstrained sequences of characters with an associated language.

anychar = %x09-10FFFF ; but not banned, as with all ABNF rules
Text    = *anychar

The URI for the Text datatype is xsd:string.

2.2 Integer

An integer is a non-empty sequence of ASCII decimal digits and represents a non-negative integer in base-10. Leading zeros have no semantic meaning and should be omitted.

Integer = 1*digit

Negative integers are not supported by this specification.

The URI for the Integer datatype is xsd:nonNegativeInteger.

2.3 Enumeration

An enumeration is a selection from a set of options. They are represented as a string matching the same production as a tag, including the rules about extensions beginning with _ (U+005F) and being mapped to URIs by a schema.

Enum    = Tag

Each enumeration value has a distinct meaning as identified by its corresponding URI.

The URI for the Enum datatype is g7:type-Enum.

2.4 Date

The date formats defined in this specification include the ability to store approximate dates, date periods, and dates expressed in different calendars.

Technically, there are 3 distinct date datatypes:

DateValue   = date / DatePeriod / dateRange / dateApprox
DateExact   = day D month D year  ; in Gregorian calendar
DatePeriod  = %s"FROM" D date [D %s"TO" D date]
            / %s"TO" D date

date        = [calendar D] [[day D] month D] year [D epoch]
dateRange   = %s"BET" D date D %s"AND" D date
            / %s"AFT" D date
            / %s"BEF" D date
dateApprox  = (%s"ABT" / %s"CAL" / %s"EST") D date

dateRestrict = %s"FROM" / %s"TO" / %s"BET" / %s"AND" / %s"BEF"
            / %s"AFT" / %s"ABT" / %s"CAL" / %s"EST" / %s"BCE"

calendar = %s"GREGORIAN" / %s"JULIAN" / %s"FRENCH_R" / %s"HEBREW"
         / extTag

day     = Integer
year    = Integer
month   = stdTag / extTag  ; constrained by calendar
epoch   = %s"BCE" / extTag ; constrained by calendar

In addition to the constraints above:

An absent calendar is equivalent to the calendar GREGORIAN.

The grammar above allows for dates to be preceded by various words. The meaning of these words is given as follows:

ProductionMeaning
FROM xLasted for multiple days, beginning on x.
TO xLasted for multiple days, ending on x.
BET x
AFT x
Exact date unknown, but no earlier than x.
AND x
BEF x
Exact date unknown, but no later than x.
ABT xExact date unknown, but near x.
CAL xx is calculated from other data.
EST xExact date unknown, but near x; and x is calculated from other data.

Known calendars and tips for handling dual dating and extension calendars are given in Appendix A: Calendars and Dates.

Date payloads may also be omitted entirely if no suitable form is known but a substructure (such as a PHRASE or TIME) is desired.

Versions 5.3 through 5.5.1 allowed phrases inside DateValue payloads. Date phrases were moved to the PHRASE substructure in version 7.0.

As defined by the grammar above, every date must have a year. If no year is known, the entire date may be omitted.

The following is an appropriate way to handle a missing year

2 DATE
3 PHRASE 5 January (year unknown)

The URI for the DateValue datatype is g7:type-Date.

The URI for the DateExact datatype is g7:type-Date#exact.

The URI for the DatePeriod datatype is g7:type-Date#period.

2.5 Time

Time is represented on a 24-hour clock (for example, 23:00 rather than 11:00 PM). It may be represented either in event-local time or in Coordinated Universal Time (UTC). UTC is indicated by including a Z (U+005A) after the time value; event-local time is indicated by its absence.

Time     =  hour ":" minute [":" second ["." fraction]] [%s"Z"]

hour     = digit / ("0" / "1") digit / "2" ("0" / "1" / "2" / "3")
minute   = ("0" / "1" / "2" / "3" / "4" / "5") digit
second   = ("0" / "1" / "2" / "3" / "4" / "5") digit
fraction = 1*digit

The above grammar prohibits end-of-day instant 24:00:00 and leap-seconds. It allows both 02:50 and 2:50 as the same time.

The URI for the Time datatype is g7:type-Time.

2.6 Age

Ages are represented by counts of years, months, weeks, and days.

Age         = [ageBound D] ageDuration

ageBound    = "<" / ">"
ageDuration = years [D months] [D weeks] [D days]
            / months [D weeks] [D days]
            / weeks [D days]
            / days

years   = Integer %x79    ; 35y
months  = Integer %x6D    ; 11m
weeks   = Integer %x77    ; 8w
days    = Integer %x64    ; 21d

Where

ProductionMeaning
<The real age was less than the provided age
>The real age was greater than the provided age
yearsa number of years
monthsa number of months
weeksa number of weeks
daysa number of days

Non-integer numbers should be rounded down to an integer. Thus, if someone has lived for 363.5 days, their age might be written as 363d, 51w 6d, 51w, 0y, etc.

Because numbers are rounded down, > effectively includes its endpoint; that is, the age > 8d includes people who have lived 8 days + a few seconds.

Different cultures count ages differently. Some increment years on the anniversary of birth and others at particular seasons. Some round to the nearest year, others round years down, others round years up. Because users may be unaware of these traditions or may fail to convert them to the round-down convention, errors in age of up to a year are common.

Age payloads may also be omitted entirely if no suitable form is known but a substructure (such as a PHRASE) is desired.

Versions 5.5 and 5.5.1 allowed a few specific phrases inside Age payloads. Age phrases were moved to the PHRASE substructure in 7.0.

The URI for the Age datatype is g7:type-Age.

2.7 List

A list is a meta-syntax representing a sequence of values with another datatype. Two list datatypes are used in this document: List:Text and List:Enum. Lists are serialized in a comma-separated form, delimited by a comma (U+002C ,) and any number of spaces (U+0020) between each item. It is recommended that a comma-space pair (U+002C U+0020) be used as the delimiter.

List      = listItem *(listDelim listItem)
listItem  = "" / nocommasp / nocommasp *nocomma nocommasp
listDelim = *D "," *D
nocomma   = %x09-2B / %x2D-10FFFF
nocommasp = %x09-1D / %x21-2B / %x2D-10FFFF

List-Text = List
List-Enum = Enum *(listDelim Enum)

If valid for the underlying type, empty strings may be included in a list by having no characters between delimiters.

A List:Text with value “, , one, more,” has 5 Text-type values: 2 empty strings, the string “one”, the string “more”, and 1 more empty string.

There is no escaping mechanism to allow lists of entries that begin or end with spaces or that contain comma characters.

The URI for the List:Text datatype is g7:type-List#Text.

The URI for the List:Enum datatype is g7:type-List#Enum.

2.8 Personal Name

A personal name is mostly free-text. It should be the name as written in the culture of the individual and should not contain line breaks, repeated spaces, or characters not part of the written form of a name (except for U+002F as explained below).

NamePersonal = nameStr
             / [nameStr] "/" [nameStr] "/" [nameStr]

nameChar     = %x20-2E / %x30-10FFFF  ; any but '/' and '\t'
nameStr      = 1*nameChar

The character U+002F (/, slash or solidus) has special meaning in a personal name, being used to delimit the portion of the name that most closely matches the concept of a surname, family name, or the like. This specification does not provide any standard way of representing names that contain U+002F.

The URI for the PersonalName datatype is g7:type-Name.

2.9 Language

The language datatype represents a human language or family of related languages, as defined in BCP 46. It consists of a sequence of language subtags separated by hyphens, where language subtags are registered by the IANA.

The ABNF grammar for language tags is given in BCP 47, section 2.1, production Language-Tag.

The URI for the Language datatype is xsd:Language.

2.10 Media Type

The media type datatype represents the encoding of information in bytes or characters, as defined in RFC 2045 and registered by the IANA.

The official grammar for media type is given in RFC 2045, section 5.1. However, that document does not give stand-alone ABNF, instead refering to registration rules and describing some components in English. The programmatic parts of the media type grammar can be summarized as follows:

MediaType    = mt-type "/" mt-subtype *(";" mt-parameter)

mt-type      = mt-token
mt-subtype   = mt-token
mt-parameter = mt-attribute "=" mt-value
mt-token     = 1*mt-char
mt-attribute = mt-token
mt-value     = mt-token / quoted-string
mt-char      = %x20-21 / %x23-27 / %x2A-2B / %x2D-2E ; not "(),/
             / %x30-39 / %x41-5A / %x5E-7E           ; not :;<=>?@[\]

mt-qstring   = %x22 *(mt-qtext / mt-qpair) %x22
mt-qtext     = %x09-0A / %x20-21 / %x23-5B / %x5D-7E ; not CR "\
mt-qpair     = "\" %x09-7E

The URI for the MediaType datatype is dcat:mediaType.

2.11 Special

The special datatype is a string conforming to a case-specific standard or constraints. The constraints on each special datatype instance are either unique to that structure type or are not simply expressed. For example, the payload of an IDNO structure may obey different rules for each possible TYPE substructure.

Each special datatype is distinct. The URI for the generic datatype subsuming all Special datatypes is xsd:string (the same as the Text datatype).

Special = Text

3 Genealogical structures

This chapter describes a set of structure types for exchanging family-based lineage-linked genealogical information. Lineage-linked data pertains to individuals linked in family relationships across multiple generations.

The genealogical structures defined in this chapter are based on the general framework of the container format and data types defined in Chapters 1 and 2.

Historically, these genealogical structures were used as the only form approved for exchanging data with Ancestral File, TempleReady and other Family History resource files. Those systems were all replaced between 1999 and 2019, and GEDCOM-X (https://gedcomx.org) was introduced as the new syntax for communication with their replacements. FamilySearch GEDCOM 7.0 and GEDCOM-X have similar expressive power, but as of 2021 GEDCOM is more common for exchanging single-researcher files between applications and GEDCOM-X is more common for transferring bulk data and communication directly between applications.

The basic description of the genealogical structures’ organization is presented in the following 3 major sections:

3.1 A Metasyntax for Structure Organization

The structures, with their payloads and substructures, are represented using a custom metasyntax. The intent of this metasyntax is to resemble the line encoding of allowable structures. In the metasyntax:

The context of a structure’s superstructure may be necessary in addition to the structure’s standard tag to fully determine its structure type. To refer to a structure in the context of its superstructure, tags are written with intervening periods. For example, GEDC.VERS refers to a structure with tag VERS and a superstructure with tag GEDC.

The FAM record was originally structured to represent families where a male HUSB (husband or father) and female WIFE (wife or mother) produce CHIL (children). The FAM record may also be used for cultural parallels to this, including nuclear families, marriage, cohabitation, fostering, adoption, and so on, regardless of the gender of the partners. Sex, gender, titles, and roles of partners should not be inferred based on the partner that the HUSB or WIFE structure points to.

The individuals pointed to by the HUSB and WIFE are collectively referred to as “partners”, “parents” or “spouses”.

Some displays may be unable to display more than 2 partners. Displays may use HUSB and WIFE as layout hints, for example, by consistently displaying the HUSB on the same side of the WIFE in a tree view. Family structures with more than 2 partners may either use several FAM records or use ASSOCIATION_STRUCTUREs to indicate additional partners.

The FAM record will be revised in a future version to more fully express the diversity of human family relationships.

The order of the CHIL (children) pointers within a FAM (family) structure should be chronological by birth; this is an exception to the usual “most preferred value first” rule. A CHIL with a voidPtr indicates a placeholder for an unknown child in this birth order.

If a FAM record uses HUSB or WIFE to point to an INDI record, the INDI record must use FAMS to point to the FAM record. If a FAM record uses CHIL to point to an INDI record, the INDI record must use a FAMC to point to the FAM record.

The individual record is a compilation of facts or hypothesized facts about an individual. These facts may come from multiple sources. Source citations and notes allow documentation of the source where each of the facts were discovered.

A single individual may have facts distributed across multiple individual records, connected by ALIA (alias, in the computing sense not the pseudonym sense) pointers. See ALIA for more.

Individual records are linked to Family records by use of bi-directional pointers. Details about those links are stored as substructures of the pointers in the individual record.

Other associations or relationships are represented by the ASSO (association) tag. The person’s relation or associate is the person being pointed to. The association or relationship is stated by the value on the subordinate ROLE line.

The following example refers to 2 individuals, @I1@ and @I2@, where @I2@ is a godparent of @I1@:

0 @I1@ INDI
1 ASSO @I2@
2 ROLE GODP

Events stored as facts within an INDI record may also have FAMC or ASSO tags to indicate families and individuals that participated in those events. For example, a FAMC pointer subordinate to an adoption event indicates a relationship to family by adoption; biological parents can be shown by a FAMC pointer subordinate to the birth event; the eulogist at a funeral can be shown by an ASSO pointer subordinate to the burial event; and so on.

The multimedia record refers to 1 or more external digital files, and may provide some additional information about the files and the media they encode.

The file reference can occur more than once to group multiple files together. Grouped files should each pertain to the same context. For example, a sound clip and a photo both of the same event might be grouped in a single OBJE.

The change and creation dates should be for the OBJE record itself, not the underlying files.

The repository record provides information about an institution or person that has a collection of sources. Informal repositories include the owner of an unpublished work or of a rare published source, or a keeper of personal collections. An example would be the owner of a family Bible containing unpublished family genealogical entries.

Layered repositories, such as an archive containing copies of a subset of records from another archive or archives that have moved or been bought by other archives, are not modeled in this version of the specification. It is expected they will be added in a later version. Until such time, it is recommended that the repository record store current contact information, if known.

A catch-all location for information that does not fully fit within other structures. It may include research notes, additional context, alternative interpretations, reasoning, and so forth.

A shared note record may be pointed to by multiple other structures. Shared notes should only be used if editing the note in one place should edit it in all other places. If each instance of the note may be edited separately, a NOTE should be used instead.

Each SNOTE.TRAN must have either a MIME or LANG substructure or both.

The origin of a name might be a reasonable shared note, while the reason a particular person was given that name may make more sense as a non-shared note.

0 @GORDON@ SNOTE "Gordon" is a traditional Scottish surname.
1 CONT It became a given name in honor of Charles George Gordon.
1 SOUR @VOID@

Although sharable notes have been present since version 5.0 was released in 1991, as of 2021 relatively few applications have a user interface that presents shared notes as such to users. It is recommended that SNOTE be avoided when NOTE will suffice.

A SHARED_NOTE_RECORD may contain a pointer to a SOURCE_RECORD and vice versa. Applications must not create datasets where these mutual pointers form a cycle. Applications should also ensure they can handle invalid files with such cycles in a safe manner.

A source record describes an entire source. A source may also point to REPOs to describe repositories or archives where the source document may be found. The part of a source relevant to a specific fact, such as a specific page or entry, is indicated in a SOURCE_CITATION that points to the source record.

This sourcing model is known to be insufficient for some use cases and may be refined in a future version of this specification.

A SOURCE_RECORD may contain a pointer to a SHARED_NOTE_RECORD and vice versa. Applications must not create datasets where these mutual pointers form a cycle. Applications should also ensure they can handle invalid files with such cycles in a safe manner.

The submitter record identifies an individual or organization that contributed information contained in the dataset. All records in the document are assumed to be contributed by the submitter referenced in the HEAD, unless a SUBM structure inside a specific record points at a different submitter record.

  +1 CTRY <Special>                        {0:1}  g7:CTRY

A specific building, plot, or location. The payload is the full formatted address as it would appear on a mailing label, including appropriate line breaks (encoded using CONT tags). The expected order of address components varies by region; the address should be organized as expected by the addressed region.

Optionally, additional substructures such as STAE and CTRY are provided to be used by systems that have structured their addresses for indexing and sorting. If the substructures and ADDR payload disagree, the ADDR payload shall be taken as correct. Because the regionally-correct order and formatting of address components cannot be determined from the substructures alone, the ADDR payload is required, even if its content appears to be redundant with the substructures.

An individual associated with the subject of the superstructure. The nature of the association is indicated in the ROLE substructure.

A voidPtr and PHRASE can be used to describe associations to people not referenced by any INDI record.

The following indicates that “Mr Stockdale” was the individual’s teacher and that individual @I2@ was the clergy officiating at their baptism.

Family events; see Family Events for more.

An event structure may be used to discuss an event even if the event is not known to have occurred. See Events for a discussion of how DATE, PLAC, and the optional Y payload indicate whether the structure is asserting the event occurred. See the NON_EVENT_STRUCTURE for how to state an event did not occur.

Family event structures vary as follows:

Individual events; see Individual Events for more.

An event structure may be used to discuss an event even if the event is not known to have occurred. See Events for a discussion of how DATE, PLAC, and the optional Y payload indicate whether the structure is asserting the event occurred. See the NON_EVENT_STRUCTURE for how to state an event did not occur.

Individual event structures vary as follows:

Indicates that a specific type of event, given in the payload, did not happen within a given date period (or never happened if there is no DATE substructure).

Substructures may provide discussion about the non-occurrence of the event but must not limit the meaning of what did not occur. No substructure other than DATE may restrict the breadth of that negative assertion.

1 NO MARR means “no marriage occurred”

]

A catch-all location for information that does not fully fit within other structures. It may include research notes, additional context, alternative interpretations, reasoning, and so forth.

Each NOTE.TRAN must have either a MIME or LANG substructure, and may have both.

See SHARED_NOTE_RECORD for advice on choosing between NOTE and SNOTE.

Although notes may be tagged with the language that they are written in, this specification does not provide a mechanism for distinguishing between notes with distinct content in distinct languages versus notes with the same content translated into distinct languages. It is expected that a future version of this specification will provide a mechanism for a single note to have multiple language translations.

The same is true for MIME: notes differing in MIME may contain the same content in a different format or contain distinct content, and this document provides no mechanism for distinguishing those cases.

A NOTE_STRUCTURE can contain a SOURCE_CITATION, which in turn can contain a NOTE_STRUCTURE, allowing potentially unbounded nesting of structures. Because each dataset is finite, this nesting is also guaranteed to be finite.

Names of individuals are represented in the manner the name is normally spoken, with the family name, surname, or nearest cultural parallel thereunto separated by slashes (U+002F /). Based on the dynamic nature or unknown compositions of naming conventions, it is difficult to provide a more detailed name piece structure to handle every case. The PERSONAL_NAME_PIECES are provided optionally for systems that cannot operate effectively with less structured information. The Personal Name payload shall be seen as the primary name representation, with name pieces as optional auxiliary information.

The name may be translated or transliterated into different languages or scripts using the TRAN substructure. It is recommended, but not required, that if the name pieces are used, the same pieces are used in each translation and transliteration.

A TYPE is used to specify the particular variation that this name is. For example; it could indicate that this name is a name taken at immigration or that it could be an ‘also known as’ name. See the NAME.TYPE enumeration for more.

Alternative approaches to representing names are being considered for future versions of this specification.

A citation indicating that the pointed-to source record supports the claims made in the superstructure. Substructures provide additional information about how that source applies to the subject of the citation’s superstructure:

When no source record is available, a voidPtr and accompanying NOTE can be used to describe the source.

1 DSCR Tall enough his head touched the ceiling
2 SOUR @VOID@
3 NOTE His grand-daughter Lydia told me this in 1980

A SOURCE_CITATION can contain a NOTE_STRUCTURE, which in turn can contain a SOURCE_CITATION, allowing potentially unbounded nesting of structures. Because each dataset is finite, this nesting is also guaranteed to be finite.

This structure is used within a source record to point to a name and address record of the holder of the source document. Formal and informal repository name and addresses are stored in the REPOSITORY_RECORD. More formal repositories, such as the Family History Library, should show a call number of the source at that repository. The call number of that source should be recorded using a CALN substructure.

3.3 Structure Meaning

3.3.1 Events

As a general rule, events are things that happen on a specific date. Use the dateRange form to indicate that an event took place at some time between 2 dates. In most cases, a DatePeriod is inappropriate for an event; if the subject of your recording occurred over a period of time, then it is probably not an event, but rather an attribute.

Event structures can be used to record notes about an event without asserting the event actually occurred. An event structure asserts the event did occur if any of the following are true:

If none of the above are true, the structure should be seen as a place for inconclusive research notes about the possibility of the event. An assertion that an event did not occur should be encoded using the NO structure.

EXID (External Identifier) g7:EXID

An identifier for the subject of the superstructure. The identifier is maintained by some external authority; the authority owning the identifier is provided in the TYPE substructure; see EXID.TYPE for more.

Depending on the maintaining authority, an EXID may be a unique identifier for the subject, an identifier for 1 of several views of the subject, or an identifier for the externally-maintained copy of the same information as is contained in this structure.

FACT (Fact) g7:FAM-FACT

See g7:INDI-FACT.

FACT (Fact) g7:INDI-FACT

If the attribute being defined was 1 of the person’s skills, such as woodworking, the FACT tag would have the value of “Woodworking”, followed by a subordinate TYPE tag with the value “Skills”.

0 @I1@ INDI
1 FACT Woodworking
2 TYPE Skills

As of version 7.0, only 2 media types are supported by this structure:

Applications are welcome to support more XML entities or HTML character references in their user interface. However, exporting must only use the core XML entities, translating any other entities into their corresponding Unicode characters.

Applications are welcome to support additional HTML elements, but they should ensure that content is meaningful if those extra elements are ignored and only their content text is displayed.

Media types are also used by external files, as described under FORM. External file media types are not limited to text/plain and text/html.

If needed, text/html can be converted to text/plain using the following steps:

  1. Replace any sequence of 1 or more spaces, tabs, and line breaks with a single space
  2. Case-insensitively replace each <p>, </p>, and <br> with a line break

Some systems use this feature to rank multiple conflicting opinions for display of most likely information first. It is not intended to eliminate the receivers’ need to evaluate the evidence for themselves.

REFN (Reference) g7:REFN

A user-defined number or text that the submitter uses to identify the superstructure. For instance, it may be a record number within the submitter’s automated or manual system, or it may be a page and position number on a pedigree chart.

This is metadata about the structure itself, not data about its subject. Multiple structures describing different aspects of the same subject must not have the same REFN value.

RELI (Religion) g7:RELI

A religious denomination associated with the event or attribute described by the superstructure.

RELI (Religion) g7:INDI-RELI

An Individual Attribute. See also INDIVIDUAL_ATTRIBUTE_STRUCTURE.

RESN (Restriction) g7:RESN

A List of enumerated values signifying access to information may be denied or otherwise restricted.

The RESN structure is provided to assist software in filtering data that should not be exported or otherwise used in a particular context. It is recommended that tools provide an interface to allow users to filter data on export such that certain RESN structure payload entries result in the RESN structure and its superstructure being removed from the export. Such removal must abode by some constraints: see Removing data for more.

This is metadata about the structure itself, not data about its subject.

REPO (Repository) g7:REPO

See SOURCE_REPOSITORY_CITATION.

REPO (Repository) g7:record-REPO

See REPOSITORY_RECORD.

RESI (Residence) g7:FAM-RESI

A Family Attribute. See also FAMILY_ATTRIBUTE_STRUCTURE.

RESI (Residence) g7:INDI-RESI

0 @I2@ INDI
1 ASSO @I3@
2 ROLE FRIEND
3 PHRASE best friend
1 BAPM
2 ASSO @I3@
3 ROLE WITN

SCHMA (Extension schema) g7:SCHMA

A container for storing meta-information about the extension tags used in this document. See Extensions for more.

SDATE (Sort date) g7:SDATE

A date to be used as a sorting hint. It is intended for use when the actual date is unknown, but the display order may be dependent on date.

If both a DATE and SDATE are present in the same structure, the SDATE should be used for sorting and positioning while the DATE should be displayed as the date of the structure.

SDATE and it substructures (including PHRASE, TIME, and any extension structures) should be used only as sorting hints, not to convey historical meaning.

SEX (Sex) g7:SEX

An enumerated value that indicates the sex of the individual at birth.

SLGC (Sealing, child) g7:SLGC

A Latter-Day Saint Ordinance. See also LDS_INDIVIDUAL_ORDINANCE.

SLGS (Sealing, spouse) g7:SLGS

A Latter-Day Saint Ordinance. See also LDS_SPOUSE_SEALING.

SNOTE (Shared note) g7:SNOTE

A pointer to a note that is shared by multiple structures. See NOTE_STRUCTURE for more.

A description of the relevant part of a source to support the superstructure’s data. See SOURCE_CITATION for more.

SOUR (Source) g7:record-SOUR

A description of an entire source. See SOURCE_RECORD for more.

SOUR (Source) g7:HEAD-SOUR

An identifier for the product producing this dataset. A registration process for these identifiers existed for a time, but no longer does. If an existing identifier is known, it should be used. Otherwise, a URI owned by the product should be used instead.

A name piece used as a non-indexing pre-part of a surname.

SSN (Social security number) g7:SSN

An Individual Attribute. See also INDIVIDUAL_ATTRIBUTE_STRUCTURE.

STAE (State) g7:STAE

An enumerated value assessing of the state or condition of an ordinance.

STAT (Status) g7:FAMC-STAT

An enumerated value assessing of the state or condition of a researcher’s belief in a family connection.

SUBM (Submitter) g7:SUBM

A contributor of information in the substructure. This is metadata about the structure itself, not data about its subject.

SUBM (Submitter) g7:record-SUBM

A description of a contributor of information to the document. See SUBMITTER_RECORD for more.

SURN (Surname) g7:SURN

A family name passed on or used by members of a family.

TEXT (Text from Source) g7:TEXT

A verbatim copy of any description contained within the source. This indicates notes or text that are actually contained in the source document, not the submitter’s opinion about the source. This should be, from the evidence point of view, “what the original record keeper said” as opposed to the researcher’s interpretation.

TIME (Time) g7:TIME

A Time value in a 24-hour clock format.

TITL (Title) g7:TITL

The title, formal or informal, of the superstructure.

A published work, such as a book, might have a title plus the title of the series of which the book is a part. A magazine article would have a title plus the title of the magazine that published the article.

For an unpublished work, including most digital files, titles should be descriptive and appropriate to the work.

TITL (Title) g7:INDI-TITL

An Individual Attribute. See also INDIVIDUAL_ATTRIBUTE_STRUCTURE.

TOP (Top crop width) g7:TOP

A number of pixels to not display from the top side of the image. See CROP for more.

TRAN (Translation)

A representation of the superstructure’s data in a different format.

In some situations it is desirable to provide the same semantic content in multiple formats. Where this is desirable, a TRAN substructure is used, where the specific format is given in its language tag substructure, media type substructure, or both.

Different TRAN structures are used in different contexts to fully capture the structure of the information being presented in multiple formats. In all cases, a TRAN structure’s payload and substructures should provide only information also contained in the TRAN structures’ superstructure, but provide it in a new language, script, or media type.

Each TRAN substructure must have either a language tag or a media type or both. Each TRAN structure must differ from its superstructure and from every other TRAN substructure of its superstructure in either its language tag or its media type or both.

TRAN (Translation) g7:NAME-TRAN

A type of TRAN substructure specific to Personal Names. Each NAME.TRAN must have a LANG substructure. See also INDI.NAME.

The following presents a name in Mandarin, transliterated using Pinyin

1 NAME /孔/德庸
2 LANG zh
2 GIVN 德庸
2 SURN 
2 TRAN /Kǒng/ Déyōng
3 GIVN Déyōng
3 SURN Kǒng
3 LANG zh-pinyin

TRAN (Translation) g7:PLAC-TRAN

A type of TRAN substructure specific to places. Each PLAC.TRAN must have a LANG substructure. See also PLAC.

The following presents a place in Japanese with a romanji transliteration and English translation

2 PLAC 千代田, 東京, 日本
3 FORM 区, 都, 国
3 LANG ja
3 TRAN Chiyoda, Tokyo, Nihon
4 LANG ja-Latn
3 TRAN Chiyoda, Tokyo, Japan
4 LANG en

TRAN (Translation) g7:NOTE-TRAN

A type of TRAN for unstructured human-readable text, such as is found in NOTE and SNOTE payloads. Each g7:NOTE-TRAN must have either a LANG substructure or a MIME substructure or both. If either is missing, it is assumed to have the same value as the superstructure. See also NOTE and SNOTE.

The following presents the same note in HTML-format English; in plain-text with the same language as the superstructure (English); and in Spanish with the same media type as the superstructure (HTML).

1 NAME Arete /Hernandez/
2 NOTE Named after Arete from <i>The Odyssey</i>
3 LANG en
3 MIME text/html
3 TRAN Named after Arete from "The Odyssey"
4 MIME text/plain
3 TRAN Nombrada en honor a Arete de <i>La Odisea</i>
4 LANG es

It is recommended that text given in text/html should only be translated into text/plain if the resulting text is different from the text created by the HTML-to-text conversion process defined in g7:MIME.

TRAN (Translation) g7:FILE-TRAN

A type of TRAN for external media files. Each g7:NOTE-TRAN must have a FORM substructure. See also FILE.

If an mp3 audio file has been transcoded as an ogg file and a timestamped transcript has been extracted as a WebVTT file, the resulting set of files might be presented as follows:

0 @EX@ OBJE
1 FILE media/original.mp3
2 FORM audio/mp3
2 TRAN media/derived.oga
3 FORM auto/ogg
2 TRAN media/transcript.vtt
3 FORM text/vtt

Note that FILE.TRAN refers to translation to a different digital format, not to translation to a different human language. Files that differ in the human language of their content should each be given their own FILE structure.

TRLR (Trailer)

A pseudo-structure marking the end of a dataset. See The Header and Trailer for more.

TYPE (Type) g7:TYPE

A descriptive word or phrase used to further classify the superstructure.

When both a NOTE and free-text TYPE are permitted as substructures of the same structure, the displaying systems should always display the TYPE value when they display the data from the associated structure; NOTE will typically be visible only in a detailed view.

TYPE must be used whenever the generic EVEN, FACT and IDNO tags are used. It may also be used for any other event or attribute.

Using the subordinate TYPE classification method provides a further classification of the superstructure but does not change its basic meaning.

A MARR with a TYPE could clarify what kind of marriage was performed:

0 @I1@ INDI
1 MARR
2 TYPE Common Law

This classifies the entry as a common law marriage but the event is still a marriage event.

Other descriptor values might include, for example,

See also FACT and EVEN for additional examples.

TYPE (Type) g7:NAME-TYPE

An enumerated value indicating the type of the name.

TYPE (Type) g7:EXID-TYPE

The authority issuing the EXID, represented as a URI. It is recommended that this be a URL.

If the authority maintains stable URLs for each identifier it issues, it is recommended that the TYPE payload be selected such that appending the EXID payload to it yields that URL. However, this is not required and a different URI for the set of issued identifiers may be used instead.

UID (Unique Identifier) g7:UID

A globally-unique identifier of the superstructure, to be preserved across edits. If a globally-unique identifier for the record already exists, it should be used without modification, not even whitespace or letter case normalization. New globally unique identifiers should be created and formatted as described in RFC 4122.

This is metadata about the structure itself, not data about its subject. Multiple structures describing different aspects of the same subject would have different UID values.

Some systems used a 16-byte UUID with a custom 2-byte checksum for a total of 18 bytes:

Use of checksums for UIDs is discouraged except in cases where error-prone input is expected and an appropriate action to take in case of an error is known.

VERS (Version) g7:VERS

An identifier that represents the version level assigned to the associated product. It is defined and changed by the creators of the product.

VERS (Version) g7:GEDC-VERS

The version number of the official specification that this document’s data conforms to. This must include the major and minor version (for example, “7.0”); it may include the patch as well (for example, “7.0.1”), but doing so is not required. See A Guide to Version Numbers for more.

WIDTH (Width in pixels) g7:WIDTH

How many pixels to display horizontally for the image. See CROP for more.

WIFE (Wife) g7:WIFE

A container for information relevant to the subject of the superstructure specific to the individual described by the associated FAM’s WIFE substructure.

WIFE (Wife) g7:FAM-WIFE

A partner in a FAM record. See FAMILY_RECORD for more.

WILL (Will) g7:WILL

An Individual Event. See also INDIVIDUAL_EVENT_STRUCTURE.

WWW (Web address) g7:WWW

A URL or other locator for a World Wide Web page, as defined by any relevant standard such as whatwg/url, RFC 3986, RFC 3987, and so forth.

If an invalid or no longer existing web address is present upon import, it should be preserved as-is on export.

3.4 Enumeration Values

Unless otherwise specified in the enumeration description in this section, each enumeration values defined in this section has a URI constructed by concatenating g7:enum- to the enumeration value; for example, the HUSB enumeration value has the URI http://gedcom.io/terms/v7/enum-HUSB.

FAMC.ADOP

ValueMeaning
HUSBAdopted by the HUSB of the FAM pointed to by FAMC.
The URI of this value is g7:enum-ADOP-HUSB
WIFEAdopted by the WIFE of the FAM pointed to by FAMC.
The URI of this value is g7:enum-ADOP-WIFE
BOTHAdopted by both HUSB and WIFE of the FAM pointed to by FAMC

DATA.EVEN

A comma-separated list of event- and attribute-type tag names. See Events and Attributes.

SOUR.EVEN

An event- or attribute-type tag names. See Events and Attributes.

MEDI

ValueMeaning
AUDIOAn audio recording
BOOKA bound book
CARDA card or file entry
ELECTRONICA digital artifact
FICHEMicrofiche
FILMMicrofilm
MAGAZINEPrinted periodical
MANUSCRIPTWritten pages
MAPCartographic map
NEWSPAPERPrinted newspaper
PHOTOPhotograph
TOMBSTONEBurial marker or related memorial
VIDEOMotion picture recording
OTHERA value not listed here; should have a PHRASE substructure

PEDI

ValueMeaning
ADOPTEDAdoptive parents
BIRTHFamily structure at time of birth
FOSTERThe child was included in a foster or guardian family
SEALINGThe child was sealed to parents other than birth parents
OTHERA value not listed here; should have a PHRASE substructure

It is known that some users have interpreted BIRTH to mean “genetic parent” and others to mean “social parent at time of birth”, definition which differ many circumstances (infidelity, surrogacy, sperm donation, and so on). Hence, applications should refrain from asserting it has either meaning in imported data.

The structures for foster children in particular, and family relationships in general, are known to have undesirable limitations and are likely to change in a future version of this specification.

NO

A single event-type tag name, but not the generic EVEN tag. See Events.

QUAY

ValueMeaning
0Unreliable evidence or estimated data
1Questionable reliability of evidence (interviews, census, oral genealogies, or potential for bias, such as an autobiography)
2Secondary evidence, data officially recorded sometime after the event
3Direct and primary evidence used, or by dominance of the evidence

Although the values look like integers, they do not have numeric meaning.

The structures for representing the strength of and confidence in various claims are known to be inadequate and are likely to change in a future version of this specification.

RESN

ValueMeaning
CONFIDENTIALThis data was marked as confidential by the user.
LOCKEDSome systems may ignore changes to this data.
PRIVACYThis data is not to be shared outside of a trusted circle, generally because it contains information about living individuals.

When a List of RESN enumeration values are present, all apply.

The line 1 RESN CONFIDENTIAL, LOCKED means the superstructure’s data is both considered confidential and read-only.

ROLE

ValueMeaning
CHILChild
CLERGYReligious official in event; implies OFFICIATOR
FATHFather; implies PARENT
FRIENDFriend
GODPGodparent or related role in other religions
HUSBHusband; implies SPOU
MOTHMother; implies PARENT
MULTIPLEA sibling from the same pregnancy (twin, triplet, quadruplet, and so on). A PHRASE can be used to specify the kind of multiple birth.
NGHBRNeighbor
OFFICIATOROfficiator of the event
PARENTParent
SPOUSpouse
WIFEWife; implies SPOU
WITNWitness
OTHERA value not listed here; should have a PHRASE substructure

These should be interpreted in the context of the recorded event and its primary participants. For example, if you cite a child’s birth record as the source of the mother’s name, the value for this field is “MOTH.” If you describe the groom of a marriage, the role is “HUSB.”

SEX

ValueMeaning
MMale
FFemale
XDoes not fit the typical definition of only Male or only Female
UCannot be determined from available sources

This can describe an individual’s reproductive or sexual anatomy at birth. Related concepts of gender identity or sexual preference are not currently given their own tag. Cultural or personal gender preference may be indicated using the FACT tag.

FAMC.STAT

ValueMeaning
CHALLENGEDLinking this child to this family is suspect, but the linkage has been neither proven nor disproven.
DISPROVENThere has been a claim by some that this child belongs to this family, but the linkage has been disproven.
PROVENThere has been a claim by some that this child does not belong to this family, but the linkage has been proven.

The structures for representing the strength of and confidence in various claims are known to be inadequate and are likely to change in a future version of this specification.

(Latter-Day Saint Ordinance).STAT

These values were formerly used by The Church of Jesus Christ of Latter-day Saints for coordinating between temples and members. They are no longer used in that way, meaning their interpretation is subject to individual user interpretation

ValueMeaning
BICBorn in the covenant, receiving blessing of child to parent sealing.
CANCELEDCanceled and considered invalid.
CHILDDied before 8 years old.
COMPLETEDCompleted, but the date is not known.
EXCLUDEDPatron excluded this ordinance from being cleared in this submission.
DNSThis ordinance is not authorized.
DNS_CANThis ordinance is not authorized, and the previous ordinance is cancelled.
INFANTDied before less than 1 year old, baptism or endowment not required.
PRE_1970Ordinance was likely completed because another ordinance for this person was converted from temple records of work completed before 1970.
STILLBORNStillborn, so ordinances not required.
SUBMITTEDOrdinance was previously submitted.
UNCLEAREDData for clearing the ordinance request was insufficient.

NAME.TYPE

ValueMeaning
AKAAlso known as, alias, etc.
BIRTHName given at or near birth.
IMMIGRANTName assumed at the time of immigration.
MAIDENMaiden name, name before first marriage.
MARRIEDMarried name, assumed as part of marriage.
PROFESSIONALName used professionally (pen, screen, stage name).
OTHERA value not listed here; should have a PHRASE substructure

4 The FamilySearch GEDZIP file format

It is often useful to transmit a dataset together with a set of external files. The FamilySearch GEDZIP 7.0 file format is provided for this purpose. Version 7.0 was the first version of GEDZIP released; the version number of a GEDZIP file is the same as the version number of the dataset it contains.

A GEDZIP file is a zip archive, as defined by http://www.pkware.com/appnote and standardized by ISO/IEC 21320-1:2015.

Each GEDZIP file contains the following entries:

All file names inside a GEDZIP are case-sensitive.

Many other zip-based file formats (such as jar, epub, docx, GEDCOM-X) assign special meaning to the zip directory META-INF and the zip file names MANIFEST.MF and META-INF/MANIFEST.MF. These have no special meaning in GEDZIP and it is recommended that they not be used in a GEDZIP file, both to avoid confusing systems that look inside zip archives to determine their file type, and to leave open the possibility of their addition in a future version of this specification.

When saved as a file, a GEDZIP should use the filename extension .gdz.

A few details about the zip archive format are useful to fully understand GEDZIP:

5 Contributors

This document was based on The GEDCOM Standard Release 5.5.1, and could not have existed without the contributors to that and previous versions of the specification. Appreciation is extended to all family history participants that have made FamilySearch GEDCOM the de facto standard for saving and transferring genealogical information.

6 Appendix A: Known Calendars and Dates

6.1 Known Calendars

This specification defines 4 calendars: GREGORIAN, JULIAN, FRENCH_R, and HEBREW. Previous versions also provided for, but did not define the meaning of, ROMAN and UNKNOWN calendars.

Extension calendars should use the usual rules for extensions, including using _ as the leading character of the calendar name. Month codes in extension calendars must either be already used for the same month name in another calendar or must start with _. Only upper case characters are allowed in month codes.

Each calendar must list its permitted epochs and their meaning.

Each month defined in this section has a URI constructed by concatenating g7:month- to the month code; for example, the month of Elul has the URI http://gedcom.io/terms/v7/month-ELL.

GREGORIAN

The Gregorian calendar is the now-ubiquitous calendar introduced by Pope Gregory XIII in 1582 to correct the Julian calendar which was slowly drifting relative to the seasons.

Permitted months are

CodeName
JANJanuary
FEBFebruary
MARMarch
APRApril
MAYMay
JUNJune
JULJuly
AUGAugust
SEPSeptember
OCTOctober
NOVNovember
DECDecember

The epoch marker BCE is permitted in this calendar; year y BCE indicates a year y years before year 1. Thus, there is no year 0; year 1 BCE was followed by year 1.

The URI for this calendar is g7:cal-GREGORIAN

JULIAN

The Julian calendar was introduced by Julius Caesar in 45 BC and subsequently amended by Augustus in about 8 BC to correct an error in the application of its leap year rule during its first 3 decades. Years had been counted from various starting epochs during the Julian calendar’s use; the version specified by this specification uses the same starting epoch as the Gregorian calendar.

This calendar uses the same months as the Gregorian calendar, differing only in which years February has 29 days.

The epoch marker BCE is permitted in this calendar; year y BCE indicates a year y years before year 1. Thus, there is no year 0; year 1 BCE was followed by year 1.

The URI for this calendar is g7:cal-JULIAN

FRENCH_R

The French Republican calendar or French Revolutionary calendar are the names given to the new calendar adopted in 1794 by the French National Convention. This calendar was adopted on Gregorian day 22 September 1792, which was 1 Vendémiaire 1 in this calendar. It was abandoned 18 years later.

Permitted months are

CodeName
VENDVendemiaire
BRUMBrumaire
FRIMFrimaire
NIVONivose
PLUVPluviose
VENTVentose
GERMGerminal
FLORFloreal
PRAIPrairial
MESSMessidor
THERThermidor
FRUCFructidor
COMPJour Complementairs

No epoch marker is permitted in this calendar.

The URI for this calendar is g7:cal-FRENCH_R

HEBREW

The Hebrew calendar is the name given to the calendar used by Jewish peoples around the world which developed into its current form in the early ninth century. It traditionally marks new days at sunset, not midnight. Its first day (1 Tishrei 1) primarily overlapped with Gregorian 7 September 3761 BCE and Julian 7 October 3761 BCE (starting at sunset on the 6th day of those months).

CodeName
TSHTishrei (תִּשְׁרֵי)
CSHMarcheshvan (מַרְחֶשְׁוָן) or Cheshvan (חֶשְׁוָן)
KSLKislev (כִּסְלֵו)
TVTTevet (טֵבֵת)
SHVShevat (שְׁבָט)
ADRAdar I, Adar Rishon, First Adar, or Adar Aleph (אדר א׳)
ADSAdar (אֲדָר); or Adar II, Adar Sheni, Second Adar, or Adar Bet (אדר ב׳)
NSNNisan (נִיסָן)
IYRIyar (אִייָר)
SVNSivan (סִיוָן)
TMZTammuz (תַּמּוּז)
AAVAv (אָב)
ELLElul (אֱלוּל)

To keep the lunar-based months synchronized with the solar-based years, some years have Adar I and others do not, instead proceeding from Shevat directly to Adar II. However, in common (non-leap) years, it is common to simply write “Adar” not “Adar II”, which users not aware of the distinction might incorrectly encode as ADR instead of ADS. It is recommended that systems knowing which years had Adar I and which did not replace ADR in common years with ADS.

No epoch marker is permitted in this calendar.

The URI for this calendar is g7:cal-HEBREW

6.2 Dual dates

The day on which a new year began and the year number increased varied at different times and places during the use of the Gregorian and Julian calendars. For example, England measured the new year as 25 March until 1752, when it switched to 1 January as the new year. In periods of transition, or when writing after a change about dates occurring before a change, it was sometimes common to indicate 2 years with a slash, for example, “30 January 1648/49” meaning “1648 if you count the new year as coming after 30 January, 1649 if you count it as coming before 30 January”. Other notations, such as abbreviations for phrases like “new style” and “old style”, were also sometimes employed.

2 DATE 30 JAN 1649
3 PHRASE 30 January 1648/49

Many nations transitioned from using the Julian calendar to using the Gregorian calendar. This transition caused a change in dates by several days, which (depending on the date in question) could change the month and year as well. In periods of transition, or when writing after a change about dates occurring before a change, it was sometimes common to indicate 2 dates with slashes, for example “23/6 November/December 1907” meaning “Julian 23 November 1907, Gregorian 6 December 1907”. Other notations, such as abbreviations for phrases like “new style” and “old style”, were also sometimes employed.

2 DATE 6 DEC 1907
3 PHRASE 23/6 November/December 1907

Some documents also used slashes to indicate approximate dates, such as writing a birth year as “1903/4” when it was computed from a year-granularity age at a given date.

2 DATE BET 1903 AND 1904
3 PHRASE 1903/4

Versions 5.3 through 5.5.1 had special syntax for recording the first of these 3 concepts with a slash in the year. However, because slashes appear in historical documents with all 3 of the above meanings, some users misused this notation to record the other 2 situations as well. The result is ambiguity in the intended meaning of the resulting data. Version 7.0 removed the year slash notation; a PHRASE substructure should be used instead to clarify meaning.

6.3 Calendars in date ranges and date periods

Calendars apply to the subsequent date production, not to the entire DateValue. Hence,

Because some systems may show dates as-is to users and because not all users understand the above rule, it is recommended that calendar tags be included if any date is non-GREGORIAN. It is recommended that the calendar tag be omitted if all dates in a payload are in the Gregorian calendar. Hence, the recommended forms of the previous 3 dates are
