[foaf-dev] Time to make the foaf classes relate to Dublin Core classes?

See http://xmlns.com/foaf/spec/#term_maker

"For example, if the thing named by the URI
http://rdfweb.org/people/danbri/ has a foaf:maker that is a foaf:Person
whose foaf:name is 'Dan Brickley', we can conclude that
http://rdfweb.org/people/danbri/ has a dc:creator of 'Dan Brickley'. "

It seems to me that foaf:maker is now 100% identical to dcterms:creator
(with range dcterms:Agent).

Time to update that part....

Also, foaf:topic sounds like a candidate for being a subPropertyOf

The foaf:topic property relates a document to a thing that the document
is about.

The topic of the resource. This term is intended to be used with
non-literal values [...]
