GEnealogical Data COMmunication
GEDCOM, an acronym for GEnealogical Data COMmunication, is a specification for exchanging genealogical data between different genealogy software.
GEDCOM was developed by The Church of Jesus Christ of Latter-day Saints as an aid to genealogical research.
Most genealogy software supports importing from and/or exporting to GEDCOM format. A GEDCOM file is plain text containing genealogical information about individuals, and meta data linking these records together. The files can be read in Notepad, Textpad or any other editor.
