Data Model

Our data model is based on the existing data and vocabularies used by the CbDD project and developed by its researchers. We only adapted data relations and vocabularies where needed to stay in line with general Wikidata (and Wikibase) data modeling principles. This data model is not set in stone and will grow organically and adapt according to user needs and requirements. Eventually it will also be synchronised with the official recommendations published by the corresponding task groups within NFDI4Culture. The following reference material is structured according to the main classes of items in the test dataset.
