I'm fond of minimalist ontologies that keep an open mind about the open world, so I like this at a glance. But I haven't looked yet to see if I think it lines up well with the Data Model). One syntactic issue about which I hope someone can point me to an authority proving me wrong: It's common practice in RDF/XML to have a DTD with XML entity declarations and use corresponding entity references in xml attributes, assuming that they will be expanded. Example: <rdfs:subClassOf rdf:resource="&rdfs;Resource"/> But to the best of my understanding, nothing in the RDF/XML specification requires that the RDF/XML serialization be valid for a DTD or XML-Schema. In particular, I believe nothing guarantees that the value of this the example is anything other than the exact contents of the quoted string, and I think that an RDF/XML parser that behaves that way is nevertheless, and horrifyingly, compliant with the RDF/XML spec. I hope I am wrong, because that use of entity reference makes a less annoying RDF file. I even like to use them in the value of namespace declarations, because then the only thing you really have to edit is the DTD.... So please, please, would someone point me at something in an RDF/XML spec that I can understand implies that entity references must be expanded; (ideally the something wouldn't make me bite the bullet and understand something deep about infosets. :-) ) Bob On Mon, Jun 18, 2012 at 3:16 PM, Robert Sanderson <azaroth42@gmail.com> wrote: > Dear all, > > If you have a moment, please check out the schema files for both the > core and extension models. > > http://www.openannotation.org/spec/core/core-schema.xml > http://www.openannotation.org/spec/extension/extension-schema.xml > > Before we put them up on the W3C site (which takes a bit more effort) > > Many thanks, > > Rob > -- Robert A.
