Hi,

> [...] I'm trying to work out the best version of a RDF type

I'm not too sure what you mean by "RDF type" here; an RDF language, or
other application utilizing RDF, perhaps? "RDF type" sounds a lot like what
you say when you read the "rdf:type" QName out loud, which is a kind of
de_facto method for referring to the type property in the RDF namespace [1]
in prose.

XML element type tags? Like SVG-in-HTML, or MathML-in-HTML? And by HTML, I
presume that you mean XHTML (I'm not sure what good XML does when it's
embedded in non-XML SGML). Perhaps you're talking about XML RDF directly
embedded in XHTML (which a notion that I'm debating against at the moment).
You'll have to be a bit more specific.

Numerous people have done work on this, but it always hides in a bit of a
"will it/won't it?" state. HTML wasn't really designed with metadata in
mind (it doesn't appear to have been designed with anything in mind, for
that matter), so it's difficult to come up with a solution for extracting
metadata from HTML that everyone is happy with, especially when some people
want DLGs, RSS feeds, human readable version of the metadata... and so on.
It's difficult to suit everyone's tastes.

I'm not too sure what you're getting at there, once again. Perhaps you mean
links to RDF documents that describe the current document, or using HTML as
a hub document to a set of related resources (which would fit in with
"portal")? This would be quite neat, but once again, it's difficult - if
not impossible - to get people to agree upon methods for doing this.

I'm not sure what you mean by these two. Hmm... and it seems to get more
dense (in the non-pejorative sense) from here on down. Some of your ideas
seem to be related to the "Semantic Cloud/SEM" thing that Seth Russell
often talks about (cf. [2]). There's also some collaborative stuff like
Annotea linked to from the Semantic Web Advanced Development homepage [3]
that may be of interest to you.
