GEDCOM
From GenWiki
GEDCOM "GEnealogical Data COMmunications"
GEDCOM is a specification for data exchange between genealogical software programs. It was developed by familiysearch.
A GEDCOM-file contains different "tags". Each tag belongs to a special content.
List of GEDCOM-Tags.
The latest "stable" version is Gedcom 5.5. The newest draft version is Gedcom 5.5.1.
Some tags as for example the tags for godparents are missing. So every software developer creates his own tags with a prefix "_". So it is no real standard and there are still some problems.
So software developers and the society of Computergenealogy in germany are developing a higher standard.
More information you can find in the article Gedcom 5.5EL.
The article GEDCOM-Test shows examples of GEDCOM-files created by different genealogical software programs.
The full GEDCOM-Test-article is at the moment only available in german: http://wiki.genealogy.net/index.php/GEDCOM-Test
