Below is a diagram of the Gramps data model (v4.1). As of October 2020, this model is reported to be valid for the v5.1 of Gramps. However, there is a minor `PlaceName` objects change in 4.2 to contain a string, language code and date range.
Primary objects are coloured blue. Secondary objects are coloured black. The dotted lines enclose object hierarchies that are stored in the database tables.
