Export Gedcom Extensions
There is an Addon (currently available for Gramps 3.5) which has a collection of unofficial GEDCOM extensions. If the feature you want is not listed below, then you can either add it yourself, or ask a developer to help you.
The code is in the Addon gramps-addons/trunk/contrib/GedcomExtensions/GedcomExtensions.py.
The code currently supports the following extensions:
- Exports witnesses associated with a family event
Running the Exporter
To run the exporter, select "Gedcom Extensions". Select the relevant options, and the data should be exported to a file with the extension ".ged2".
Currently, there is not an associated .ged2 importer in Gramps, so the current export is one-way only (out of Gramps). It would be easy for someone to also write an associated importer to handle the extensions.
