{{stub}}Gramps uses [[Gramps XML]], which is a less confining format than '''''standard''''' [[GEDCOM]].
Although Gramps uses [[is able to import '''''basic''''' genealogical data from GEDCOM through its GEDCOM Import module, much data commonly handled in modern Genealogical software can not be described while staying within the confines of the GEDCOM standard. So, GEDCOM Export from a Gramps Family Tree or Gramps XML]] which is considered necessarily a superior format to '''lossy''' operation. {{man tip|Gramps state of the GEDCOM art|[[Import_from_another_genealogy_program#Standard_GEDCOM_as_transfer_tool|GEDCOMhas become the de facto standard]] for [https://wikipedia.org/wiki/Schema_crosswalk schema crosswalking]basic family history data between programs.<br/>Because [https://wikipedia.org/wiki/Dialect#Standard_and_nonstandard_dialects dialects] by the can arise for each program that writes GEDCOM files, we openly document where that additional layer of data loss occurs. But, since dialects cause incompatibilities in data exchange, we strive to avoid a "Gramps developersaccented" dialect of GEDCOM.
Although The 2018 revision of a blog article by Keith Riggle is a frank evaluation of GEDCOM dialect issues between [[Import_from_another_genealogy_program#Family_Tree_Maker|Gramps should be able & Family Tree Maker]].}}This page attempts to import most data list information that is lost on a GEDCOM export from GEDCOM through its GEDCOM Import moduleGramps, many of the so that users may choose to restrain their Gramps use to those features are not supported by that GEDCOM can handle. Gramps recognizes the relevance of GEDCOM standard and so GEDCOM Export from a Gramps Family Tree or Gramps XML is a '''lossy''' operationattempts to offer the broadest compatibility possible.
This {{man note|The Gramps version used as a reference for this page attempts to list information that is lost on a GEDCOM export from |GrampsTrunk, so that users may choose to restrain their which at the time was Gramps use to those features that GEDCOM can handle3.

{{man note|The Gramps version used as evolution of the GEDCOM standard stalled on 10 January 1996. There was a reference 1999 draft for this page is|Gramps Trunka GEDCOM 5.5.1 version, which at became the time de facto standard but wasn't officially endorsed until November 2019. (The GEDCOM 7 specification was Gramps 3officially published in June 2021.3.(Released:2011-06-12)}}
The GEDCOM standard stopped evolving on 10 January 1996. There is a draft for a Gramps uses several features of GEDCOM 5.5.1 version, of which Gramps uses several features as noted below.
The following assumes the 5.5.1 standard for the GEDCOM export utility. However, there is also a set of common extensions that have been bundled togetheras another dialect writable by Gramps. See [[Addon:GEDCOM Extensions]] for more information.
* '''Parish''' Church Parish fields in Locations
* '''Media Attributes''': no equivalent in GEDCOM.
* '''Source Attributes (previously Data)''': no equivalent in GEDCOM.* '''Source and Date 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.
* '''Tags''': an organizational tool for data analysis. This is not real genealogical data.
* '''Shared Events''': will generate the same event for each record. On import Gramps tries to merge equal events.
* '''Events order''': like for children, GEDCOM ignores events order.
* '''Shared Places in events''': GEDCOM does not know the concept of sharing places, so places are duplicated in the GEDCOM. On import, Gramps will automatically merge places with the ''same'' title and street, so this should be of no influence.
* '''Call Name''': no equivalent in GEDCOM.
* '''Persian, Islamic, Swedish calendars'''
* '''Dual date and non 31/12 new year'''
* '''Independent event, source, citation, media, repository, note''': GEDCOM needs INDIvidual or FAMily as top level.
* Some '''Gramps' Types''' (Note, Repository, Repository reference, etc ...)
* No GEDCOM data structure exists for the [[Hierarchical Place Structure|place hierarchy]] introduced in Gramps version 4.1.
 
* See also [[Lossless_GEDCOM_Export|Lossless Export]] and [[Addon:GEDCOM_Extensions|GEDCOM Extensions addon]].
== Information written in other form on GEDCOM export ==
* '''Compound surnames''': all name grouping info is present using comma-separated lists. Using the ''[[Gramps_5.1_Wiki_Manual_-_Tools#Extract_Information_from_Names|Extract Information from Names]]'' tool, such a GEDCOM can be converted again in grouped names.
== Information available in GEDCOM 5.5.1 form ==
== Information in GEDCOM 5.5 not in Gramps (lost on import) ==
{{man note|Gramps 4.1 GEDCOM Import|Details of GEDCOM import for Gramps 4.1 are already provided in the [[Gramps_4Gramps_5.1_Wiki_Manual_-_Manage_Family_Trees#Importing_data|Gramps 4.1 manual's Importing Data section]], and '''will not be repeated here'''.}}
