PROV defines prov:SoftwareAgent [1] which might be appropriate. There
are also prov:Organization and prov;Person.

In the PROV-Dublin Core Terms mapping we make dct:Agent
owl:equivalentClass prov:Agent. I think it should also be equivalent
to at foaf:Agent, but we've not formally stated that anywhere.
