you raised an issue with the RDF recommendations which was captured in



It is suggested that the novel use of subclass and instance relationships 
in RDF will be hard for those familiar with object oriented programming to 
understand and that a clearer discussion of the application of these 
relationships, especially when the same resource is both an instance and a 
subClass would be helpful.

As recorded in


the RDFCore WG has decided to close this issue on the grounds

  - subClassOf and rdf:type are defined in the RDF Model Theory

  - the RDF Schema spec and RDF Primer provide adequate descriptions of 
these properties

The formal wording of the resolution is a bit bare, but basically what this 
means is that the WG has decided that the new model theory document 
(http://www.w3.org/TR/rdf-mt/) provides a clear formal specification of the 
meaning of this construct, and the new rdf primer provides a clear 
(http://www.w3.org/TR/rdf-primer/) informal informal treatment.

Please could you respond to this message, copying www-rdf-comments@w3.org 
indicating whether this is an acceptable resolution of this issue.
