The community database is the database that is created by our users, directly in this wiki. Wikidata provides the possibility to have several distinct database coexist in one wiki. However, OmegaWiki now only has the Community Database. In the past, there was also SwissProt and UMLS. SwissProt is now developed in a separate wiki.
It consists of definitions and translations in all languages. It is continuously growing. Statistics about the community database are accessible at the page Special:Ow statistics.
