I am trying to convert a database to RDF format.I am using the usual Dublin core vocabulary and the foaf to make the representations.The problem is that my database has some weird columns that does not exist on the Dublin core.How can I model these properties?Do I have to create my own vocabulary or Am I able to use a similar vocabulary?(e.g a similar vocabulary in XML/RDF format from freebase)
http://rdf.freebase.com/rdf/film.actor is one of the schema that I am planing to use. Can this one be considered as a correct one?
