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

I'm still not understanding you.

What is this "extended RDF"? I'm not even sure I can guess what it is.
> it used to be. THe best actions to create a Semantic Web IMO are (based on

> 1. Create XML to RDF extraction tools.
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.
> 5. Stop moaning about it and get to work!
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.
