Gramps data model (v5.2) |
Gramps uses the pickle module to serialise object hierarchies and store them in the database.
Details of the pickle module can be found here:
The Places Model Enhancements planned for v5.3 are expected to have deeper changes. One target for that Gramps Proposal includes this documentation.
Primary objects are coloured blue. Secondary objects are coloured black. The dotted lines enclose object hierarchies that are stored in the database tables.
