I don't know what this means.  What is this "language"?  Is it an XML
vocabulary/schema?  What is this "correct"?  Is it a matter of authority
to use a namespace?

Even more confused now.  How does making namespaces dereferencable solve
whatever problem obtains from having different languages reference a
single namespace?

I'm still not understanding you.

What is this "extended RDF"?  I'm not even sure I can guess what it is.

Happenning all the while.  Examples include Jonathan Borden's work, and
that of Dan Connolly, who even has a system for extracting RDF from
RFC822.  There is much knowledge staggering about the ether in RFC822.

>      2. Create notepad databases of RDF

Can you explain this?

>      3. Link ontologies to real world problems

This should be a fundamental requirement of any ontological engagement.  I
haven't heard of efforts that don't meet this.

>      4. Create GUIs for the RDF model

See the work of Dan Brickley and others.  One of my Fourthought colleagues
is doing some work in this field as well.

Well, from your 1, 3 and 4, I'd have to conclude that the semantic Web is
well on the way, but I think your list is not exhaustive.
