What do you mean by "data model" that RDF doesn't already provide?

I don't see the need for optimism. This is an enabling technology meant
to handle cases such as;
a) you want to reuse an existing ontology verbatim
b) you want to reuse an existing ontology and extend it with your
own ontology
c) you have an existing ontology that you want to map to a well known
one
d) you want to develop a completely proprietary ontology and provide no
mapping
e) you want to develop a proprietary ontology but provide a mapping,
possibly partial
(... and certainly others I haven't thought of)
The Semantic Web - vision or technologies - doesn't depend on these
mappings existing since it has to (and does) support case d). Of
course, the more instances of case d) out there, the fewer cases of
open, ad-hoc integration we'll see, but that has little to do with the
technology, and everything to do with market forces.
