RE: RDDL is bad, replace it with my RDF
What Ken says is correct. The difference between a URI and a URL is in the eye of the beholder, or application. Syntactically, they are the same. This is one of the basic inconsistencies of the web architecture: it claims locations and names are the same thing and that can result in ambiguous semantics/interpretations. The philosophy of identity (a property or a process?) has been discussed endlessly here and elsewhere. In practice, the RDDL file is the least powerful resource one can put at the location so named. Thus it is consistent with Web Architecture principles. As Ken says you are free to put an RDF resource there or a picture of your mother in law. Use will vary by need. len -----Original Message----- From: G.

Exactly! And when you add RDDL to it the XHTML is also useful to computers. Which is why I think XHTML+RDDL at the URL of a URI is perfectly suited. I find in class that many students come to my class thinking that going to the URL of a namespace URI is important ... and putting XHTML at the URL of a URI makes it useful (though no more important than it was). Useful to those without tools to read the RDDL and useful to those with tools to read the RDDL. Useful, but not important. >Even if someone will oppose me, I will insist lobbying placing RDF >code at NS URLs. Fine ... different strokes for different folks. But if someone without an RDF tool visits the URL of your URI, would they get as much out of the page of data? >I will provide a link from my RDF into an RDDL however. Not sure what that means. Do you mean a link into an XHTML+RDDL document? . . . . . . . . .
