Do we want to use `prov:atLocation` or `prov:location` here? 

After thinking/reading a bit more about the use of `prov:atLocation` vs `prov:location, I believe we want to use `prov:location` in representations that are limited to the semantics of prov-dm, and reserve the use of vocabulary from the prov ontology for rdf serializations like turtle and json-ld.
