Gramps XML
Gramps XML is the Extensible Markup Language XML format designed for storing Gramps data. The goal is to have a fully portable, human- and machine-readable XML format so that the data can be read and written without any loss. In addition, XML format allows for smaller files (if compressed) and for using the version control system for tracking the changes (if uncompressed).
The reason XML is not used by Gramps as the working database ("internal") format is performance, specifically memory considerations.

Note: To convert an old Gramps XML file you could use VirtualBox or Vmware and the old lgenealogy images from: |
DTD generation
Tool like xml2dtd could help people not familiar with DTD grammar by generating a DTD file from a XML file. New content on Gramps XML could be tested with the tool and be merged on current Gramps DTD.
RELAX NG generation
Tools like trang or NekoDTD could help to convert a Gramps DTD file to a RELAX NG file. Some others tools and up-to-date informations are listed on this page.
Validating Gramps XML file
To validate the Gramps XML file against its DTD, use xmllint program (comes with the libxml2-utils package):
xmllint --noout filename.gramps
|
If the Gramps XML file does not validate this indicates an error in either the DTD or the XML Writer. |
Parsing Gramps XML file
- XSLT scripts: gramps exhibit (Michiel Nauta), Ancestors.xsl, Birthday.xsl (Gramps 1.x), Tellico scripts, lxml gramplet, Print Notes, etc ... see XPaths.
- A sample of standalone script (Adam Sampson) which parses a Gramps XML file for drawing a family tree.
- Gramps-php-exporter
- A Joomla! component/module for uploading the Gramps XML database and for showing genealogical information and overviews.
- PhpGedView supports simple output to Gramps XML file format for the Clippings Cart and has an option to download entire Gedcom in Gramps XML form as well as being able to retrieve raw data from the SOAP web service in Gramps XML format. Still a partial support on version 4.3.0.
- Greasemonkey scripts (Michiel Nauta)
- GrampsXMLview is a number of PHP scripts in combination with a Gramps XML database.
