I am trying to convert some data to RDF format. I can create basic ontologies using the dc and foaf types. The problem is that for more complex ontologies, I need some more specific predicates. I'm looking for some more specific dictionaries, but I'm not sure what the dictionary means. Is it just a URI (maybe some site) with information about the terms I want to use, or should it be written in RDF format? Example: Can I use IMDB terminology? e.g. http://www.imdb.com/glossary/C
You should not use external URIs for RDF predicates that are not part of the dictionary (defined by the domain owner).
