Tim, I just read your piece at XML.com on the RDF, and, using your, example, I want to make sure I have each part the RDF clear: <RDF:Description href='http://www.textuality.com/RDF/WhyRDF.html'> <Author>Tim Bray</Author> <Home-Page RDF:href='http://www.textuality.com' /> </RDF:Description> All right, let's see: The resource being described here is the resource at location http://www.textuality.com/RDF/WhyRDF.html The PropertyType resources here are Author and Home-Page. The Property is Description. It consists of the resource, the property types Author and Home-Page, and each one's corresponding value. Now, given that, we could perhaps add an id attribute to the RDF element, say, "description", and then further describe this entire property with something like: <RDF:Indexer href="#description"> <Person>Adam Donahue</Person> </RDF:Indexer> Now the resource is the Description property, and the property type of *this* resource is Person, indicating here, for example, the person who indexed the original description. Further, I could add an id attribute to the Person element, say, persontype, and then describe to a particular the Person PropertyType in the Indexer resource, like: <RDF:Person href="#persontype"> <Desc>...</Desc> </RDF:Person> Now, if this is true, I'm a bit confused. What if I have several <RDF:Indexer> elements in my document. How do I describe, *in general*, a Person PropertyType? It would appear that if I point to a particular instance (as in this example), it would only apply to this instance? Does this make sense? That is, I have a unique ID as an attribute to the Person PropertyType in the above. I am pointing to it in <RDF:Person href="..">, but this element only points to the ID of *that* particular Person PropertyType (namely, the one containing "Adam"). What if I have one with Bob? And what if I just want to describe the PropertyType itself, in general? I'm missing something here. Please clarify... Thanks, Adam mailto:adam@c... xml-dev: A list for W3C XML Developers.
