[protege-discussion] Error change from 3.0 to 3.2

We are not supporting the RDF Backend anymore. This plugin has been 
developed a long time ago for one of the first versions of Protege and 
the developer is not working at Stanford anymore. However, we are 
planing on providing a better RDF(S) support in the Protege 4 version.

Until then, you can use the OWL/RDF backend to edit RDF(S) files without 
loosing your sub-models structure. You can use the owl import mechanism 
to mimic the project inclusion in frames. You can create an *.rdfs file 
that contains your classes definitions and then import it into an *.rdf 
file that contain the instances.

The created content will be RDF(S). For example the classes will be 
rdfs:Class-es and the properties will be rdf:Property-ies. However, if 
you use the owl import mechanism you will see the owl:import statement 
in the rdf file, which is in the end also rdf. Besides that, all the 
content will be "pure" RDF(S).
