I keep thinking I understand RDF and then I look at DCD and think "I guess I don't." DCD is supposed to be an RDF vocabulary, right? I know that it uses some extensions to RDF (argh!), but even so, I don't see how it works. Rdf :: = [ <rdf:RDF> ] description * [</rdf:RDF>] It is odd to me that the RDF wrappers are optional and that not even an RDF identifying attribute or processing instruction is required, but okay let's presume that we "know" that a DCD is an RDF and have just left off the wrapper elements. That means that the root DCD element is a description. description ::= typedNode typedNode ::= <typeName ...> property* </typeName> But DCD says DCD ::= <DCD> elementDef * </DCD> (I presume...I can't actually find a grammar in the DCD spec. but I haven't looked hard...it certainly isn't in the table of contents) So what are the properties of the DCD node? Just ElementDef and AttributeDef? Am I to understand that these are vector-valued properties? People complain about SGML minimization, but RDF abbreviation is much more complicated. Perhaps someone can walk me through the expansion of A DCD document into completely described nodes and properties.
