The GEDCOM X Date Format

The GEDCOM X date format specifies a mechanism for representing dates, with specific attention given to the need to represent genealogical dates.

 


The GEDCOM X Conceptual Model

The GEDCOM X conceptual model is a specification of formal concepts and data types that are used to model genealogical data. Genealogical data is represented using data types such as persons, relationships, and sources.

 


The GEDCOM X XML Serialization Format

The GEDCOM X XML Serialization Format is a specification that defines the way that the GEDCOM X Conceptual Model is serialized to and deserialized from XML.

 


The GEDCOM X JSON Serialization Format

The GEDCOM X JSON Serialization Format is a specification that defines the way that the GEDCOM X Conceptual Model is serialized to and deserialized from JSON.

 


The GEDCOM X Standard Header Set

When processing a set of genealogical resources, it is often useful to process metadata for the resource before processing it. Examples of this kind of metadata include:

  • The data format for the resource.
  • Caching directives such as the last modified timestamp or version.
  • Identifiers for the resource.
  • Bibliographic metadata, such as a bibliographic citation.
  • Display names or titles.

The GEDCOM X Standard Header Set specifies the set of metadata terms that are recognized for genealogical resources and the mechanism for providing that metadata.

 


The GEDCOM X File Format

A GEDCOM X file is a bundle of digital genealogical resources, such as data that has been gathered through the genealogical research process about persons, relationships, sources, images, etc. The GEDCOM X File Format defines a mechanism to bundle all of these resources into a single file and defines a mechanism whereby each resource within the bundle may refer to other resources within the same file.

 


GEDCOM X Event Types

The GEDCOM X Event Types specification provides a set of enumerated values that identify common event types that are relevant to genealogical research.

 


GEDCOM X Fact Types

The GEDCOM X Fact Types specification provides a set of enumerated values that identify common fact types that are relevant to genealogical research.

 


GEDCOM X Name Part Qualifiers

The GEDCOM X Name Part Qualifiers specification provides a set of enumerated values that identify common qualifiers of name parts that are relevant to genealogical research.

 


Record Specifications

GEDCOM X Record Extensions

The GEDCOM X Record Extensions specification provides a set of extensions to GEDCOM X for providing a mechanism to exchange field-based genealogical record data.

 


GEDCOM X Field Types

The GEDCOM X Field Types specification enumerates a set of field types for use in exchanging field-based genealogical record data.

 


Web Service Specifications

GEDCOM X Atom Extensions

The GEDCOM X Atom Extensions specification specifies a set of genealogical data extensions to RFC 4287, The Atom Syndication Format.
