> Since DAML is based on XML [...] I'd argue that it isn't - I can use DAML terms in any RDF graph, and RDF can be serialized into formats other than XML RDF. For example, further down in this email, I restate the triples in your second example in another format called NTriples. There's also another format called Notation3 [1], which is a superset of NTriples. Any of these are fine for expressing an RDF graph, although people tend to prefer one format above the others. You're right that XML RDF can be parsed using an XML parser, but the main purpose of XML RDF is to just serialize the triples. XML RDF is not a linear document format: the position of each triple does not matter. > Which other triples can be stated from the above > code? Try running it through the RDF Validator [2]. You get the following triples:- [[[ <online:#Member> <label> "Member" . <online:#Member> <comment> "represents a member of the lecturing staff" . <online:#Member> <subClassOf> <http://www.daml.org/2001/03/daml+oil-ex#Person> . <online:#Member> <subClassOf> <http://cicho0.tripod.com/cs_Staff_ont#Lecturing-Staff> . _:j11091 <http://www.daml.org/2001/03/daml+oil#maxCardinality> "1" . _:j11091 <http://www.daml.org/2001/03/daml+oil#onProperty> <online:#hasOffice> . _:j11091 <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://www.daml.org/2001/03/daml+oil#Restriction> . <online:#Member> <subClassOf> _:j11091 . <online:#Member> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://www.daml.org/2001/03/daml+oil#Class> . ]]] The "online:" scheme is a terrible bit of chaff that the validator added to your input. It can be excused since you used "rdf:id", which is fine in an example, but I would advocate using "rdf:about" in real life code, for obvious portability reasons.
