Wikidata:WikiProject Ontology

WikiProject Ontology

The WikiProject Ontology is mainly about reaching deep into the nature of being, becoming, existence, and reality, and applying those insights during Wikidata's maintenance tasks. The more practical aims of the project are:

  • to support a broad semantic interoperability between notable ontologies like DOLCE, BFO, SUMO, Lemon, RDA, etc.
  • to build consensus around the main branches of our core concept tree and how they relate to each other
  • to gain a deep understanding about the meaning of our upper ontology and to transfer this knowledge to others in practical terms

For specific subject areas, the class hierarchy and properties may be covered in detail on a WikiProject page devoted to that subject - for example Wikidata:WikiProject Books, Wikidata:WikiProject Names or Wikidata:WikiProject Chemistry.

We have an active task force that is part of this WikiProject and works to improve the Ontology at Cleaning Task Force.
