It seems there's a kind of distinction here between vocabularies and ontologies. I have some wooly ideas what these might be, but I'd be interested if anyone can offer a sharp definition. (In the sense that "http://www.w3.org/1999/02/22-rdf-syntax-ns#" does define some vocabulary, but not an ontology, and "http://www.daml.org/experiment/ontology/beta/elements-ont#" is viewed as defining an ontology.) #g -- At 06:49 PM 4/21/02 -0400, Drew McDermott wrote: [...] ><rdf:RDF > xmlns:rdf ="http://www.w3.org/1999/02/22-rdf-syntax-ns#" > xmlns:rdfs ="&rdfs;#" > xmlns:daml ="&daml;#" > xmlns:xsd ="&xsd;#" > xmlns:enp ="http://www.daml.org/experiment/ontology/beta/elements-ont#" > xmlns:soci= > "http://www.daml.org/experiment/ontology/beta/social-elements-ont#" > xmlns:poli= > "http://www.daml.org/experiment/ontology/beta/political-elements-ont#" > xmlns:econ= > "http://www.daml.org/experiment/ontology/beta/economic-elements-ont#" > xmlns:infr= > "http://www.daml.org/experiment/ontology/beta/infrastructure-elements-ont#" > xmlns:info= > "http://www.daml.org/experiment/ontology/beta/information-elements-ont#" > xmlns:mil > ="http://www.daml.org/experiment/ontology/beta/military-elements-ont#" > xmlns:assess ="&assess;#" > xmlns:obj ="&obj;#" > xmlns:loc ="&loc;#" > > > >Now we can all see that all but the first 4 of these are clearly >ontologies to import.
