Gramps uses [[GRAMPS_XML|Gramps XML]] which is considered a superior format to [[GEDCOM]] by the Gramps developers. Although Gramps should be able to import most data from GEDCOM through its GEDCOM Import module, many of the Gramps features are not supported by the GEDCOM standard and so GEDCOM Export from a Gramps Family Tree or Gramps XML is a lossy operation. This page shall list all the information that is lost on a GEDCOM export from Gramps, so that users may choose to restrain their Gramps use to those features that GEDCOM can handle. Gramps recognizes the relevance of GEDCOM and attempts to offer the best compatibility possible. The Gramps version used as a reference is Gramps Trunk, currently which at the time was Gramps 3.3.
The GEDCOM standard stopped evolving on 10 January 1996. There is a draft for a 5.5.1 version, of which Gramps uses several features as noted below.
The following assumes the standard GEDCOM export utility. However, there is also a set of common extensions that have been bundled together. See [[GEDCOM Extensions]] for more information.
__TOC__
* '''Source Data''': no equivalent in GEDCOM.
* '''Source on places''': no equivalent in GEDCOM.
* '''Event Attributes different from age, father age, mother age, cause, agency'''. These other attributes have no equivalent in GEDCOM. AGNC and CAUS are exported from Agency and Cause attributes (respectively) of an event. AGE, HUSB:AGE and WIFE:AGE are exported from Age, Father's Age and Mother's Age (respectively) of an event reference. Hence these items of data should be stored in the appropriate place for export.
* '''Media Description''': set by user, no equivalent in GEDCOM.
* '''Reference region of a media reference'''.
