Anyone can say anything about a namespace. The rule that isn't
worked out is who will listen to them and how they will listen.
It's a complex problem that tries to take into account all the
ways an instance can be used! Such is the nature of
generalization...less than trivial, and I sure don't have it

The data in the two formats is pretty similar. Typekit uses
nature and purpose as well. It adds one more property,
mime-type, which indicates in the case of a transformation, what
the target mime-type of that transformation is. This property
is optional however.
I'd like to find some kind of harmony between RDDL and typekit,
so let me lay my cards on the table and say what I do and don't
like about RDDL.
* functionally, RDDL does a lot of the same things typekit does,
and it's developed here.
* nature/purpose is I think brilliant starting place for
generalizing the description of a resource.
* the name RDDL is a descriptive name for what I've been calling
a typekit descriptor.
* RDDL is an extension of XHTML, which joins data and
presentation in a way that IMHO would be better accomplished by
browser support for intelligently displaying XML. Granted, this
support doesn't exist currently, but I think it could using
something like this project.
* RDDL is already an emerging standard, and it's a little
different from the direction typekit is headed. Part of the
reason for inventing a new spec with some overlapping goals is
to have a place to experiment and try new things without having
to worry about an existing standard.
* Why RDF?
That said, I'm definately interested in working with what's
already out there, and there is a lot of space where the two
