I am trying to convert a database in RDF format.
At the moment I am using some vocabularies from freebase.com and schema.org as well as the default ones (dc,foaf,etc). Now the problem is that for some properties I can't find the terms in the vocabullaries so the only way is to create my own schema as fas as I understand.
When I create the schema I want define some extra properties of a class (say class A).I am thinking of creating a subclass of class A and define there all the properties that I need.Is this the right way to do that? If one of my instances is for example an instance of class A is it allowed to define properties as foaf,or dc or do I have to define anything extra in my vocabulary. If I want to extend an existing vocabulary in my project are there any extra constraints?
