Using Wikidata as an Authority for the SowiDataNet Research Data Repository
3 likes4,832 views
Wikidata provides a comprehensive authority for geographical entities that can be used by the SowiDataNet Research Data Repository. Wikidata contains countries, German states, the European Union, and geographical regions without needing to create a custom authority. A custom query can access just the required geographical data items from Wikidata, gaining identifiers, multilingual labels, links to other identifiers, and abundant information from Wikipedia with minimal cost and effort compared to maintaining a custom authority.
