Anthony,
We do, as a community, agree on the Schema.org Vocabulary Terms and debate
them at length sometimes on mailing list and Github issues, and even put
them into https://pending.schema.org (for early review).
Wikidata stores more than just instance data, they are also a controlled
vocabulary where the control is in the hands of the community as well.
