Re: The Agent proposal in bib.schema.org is controversial

FWIW, the Bibliographic Ontology (bibo) also uses foaf:Agent.

But I concur with the developing dissenting opinion on the github issue
that, if we have nothing specific to say about the nature of the entity
because we lack the information, it's better to simply avoid the compromise
of Agent. We might make ourselves feel a bit better about the dismal state
of our bibliographic data through an abstract class like Agent, but in the
end it doesn't really add any data to the data we're trying to express.

Using schema:Thing seems like an acceptable fallback in the mean time, and
allows the data expressed by the target links to be refined to either
Person or Organization at some point in the future when the effort occurs.
