Data model

Our data model is mostly based on existing data and vocabularies found on Wikidata; we added data relations and vocabularies where needed to provide needed information for the EPFO website and charts.

This data model is not set in stone and will grow organically according to the needs and requirements of our work.

Here are the properties for the main classes of items.
