I was thinking about the challenge you set in an earlier message: get an
inexpensive tool allowing to do some useful work with RDF. Here is one, a
free one: Protégé. You can import-export RDF statements and create forms to
fill the slots (i.e. property's values). Creating a form is quite easy. With
this form you can create other RDF statements and even link them together
and see the result in a graph. The critic I may have against the tool is too
much emphasis on a platonic approach; I would prefer a prototype approach.

Now it's your turn Eliotte do you know a tool allowing me to
create/update/manipulate set of resources/objects? If you mention an XML
editing tool then fair enough, how can I get a graph of related or linked
resource with these tools? I won't speak of filling or creating an XML
document since altova is providing a free tool for that. So the form part of
the tool is already created. Now how about having property set linked
together to express associations between concepts?
