Agreed that it's not specific to RDDL. And probably everyone
agrees on that.
But this isn't the general URI case. We have a very specific
looming issue (that's my hunch anyway) of large chunks of web
infrastructure depending (perhaps unwisely) on being able to
retrieve resources on the ends of particular well-known URIs on
a regular basis ... a lot of them hosted by the W3C, a lot of
them hosted elsewhere. I predict server meltdown.
You could argue that people who build XML applications
_shouldn't_ fetch a fresh copy of the corresponding XML
DTD/Schema every time they parse a fresh document instance. And
you'd be right, but that won't stop people doing it.
That's my justification for a new protocol. But I think that
there's also a very close connection with some of the areas we've
been discussing here wrt, RDDL and xmlcatalog. Both allow for
local overriding via what is to all intents and purposes a
local cache. I suggest we at least look at whether there's
enough similarity between the two scenarios to make it worth
coming up with a uniform solution.
