Export GEDCOM Extensions

The following GEDCOM Extensions are supported:

• Exports witnesses associated with a family event
• Include media

Usage

To run the exporter, select Family Trees > Export.., press Next, on the Choose the output format dialog select "GEDCOM Extensions (GED2)", press Next. On the Export options dialog select the relevant GEDCOM extension option:

• Include witnesses - (checked by default) Exports witnesses associated with a family event
• Include media - (checked by default)

Then press Next, and after selecting the save location and applying the export the data should be exported to a file with the extension ".ged2".

Afterwards, you can change the extension from ".ged2" to ".ged" and treat as a normal GEDCOM file.

Warning There is no associated .ged2 importer in Gramps, so the export is one-way only (out of Gramps). It should be possible for someone to also write an associated GEDCOM importer to handle the extensions to bring them into Gramps as well.

Others projects

• GEDCOM (WeRelate.org) is a project for parsing objects ignored by a model. It includes classes and attributes for every GEDCOM tag sequence appearing in more than 4% of the 7000 GEDCOMs submitted to WeRelate.org over the past five years, with the exception of four software-specific schema tags: SCHEMA, _EVENT_DEFN, _PLAC_DEFN, and _EVDEF, generated by Family Tree Maker, Personal Ancestral File, Legacy, and RootsMagic respectively.

See the demo[1]. GEDCOM -> model -> json -> model -> GEDCOM round-trip shows the GEDCOM tags that are represented in the model as extensions, and tags that cannot be represented.
