Dear all, I'm new to RDF and have some questions about RDF M&S and RDFS: a.In RDFS(http://www.w3.org/TR/2002/WD-rdf-schema-20020430/)why Property is defined in the namespace of RDF while Class in RDFS? In my opinion,Class is the class name of nodes and Property is the class name of arcs. They seem to have the same statuses. b.I read some RDF api proposals.Most of them define Statement, Model,Container as subclasses of Resource. Could them be manipulated as Resources in RDF models? I think they are boxes containing Resources but not Resources. c.In API,should Property be defined as a class (for example, in Java, Proeprty maybe be defined as a subclass of Resource) or an instance of Resource named as "Property"? If it is a java class, I wonder how to understand the situation when an instance of Property is put in a statement as subject or object(maybe in a schema,a property p is in a triple (p,subPropertyOf,ppp)).
