I think it is important to stress for casual readers of this mailing list that we have entered into an academic discussion that is of unclear importance for actually building the Semantic Web. Intellectually, I really enjoy the thread, but 1. there is no class for "paddle surfboats" in the Vehicle Sales Ontology (just vso:Watercraft) 2. as stressed, the relevance of recreational watercrafts for Semantic- Web-based e-commerce is limited. At least they are not likely to be more important than car sales and rentals. Google reports more than 3.7 Million Web documents for "Semantic Web", of that more than 230,000 in PDF (likely papers, technical reports, theses,...). In contrast, there are less than 50 ontology namespaces used in more than 1,000 RDF documents (according to PTSW). If ontologies, however lightweight or heavy-weight, are agreed to be essential for the Semantic Web to become a reality, then we will need way more efforts to produce and maintain those. Best Martin PS: Funny thing: The original GoodRelations paper was rejected for ESWC 2008; the main argument was that "building an ontology is not really a relevant contribution". I guess I will post the paper and the reviews one day ;-) On 09.09.2010, at 17:02, Barry Norton wrote: > On 09/09/10 16:58, Frank Manola wrote: >> For completeness, don't leave out "boats propelled by arm muscles >> holding a pole", as in punts (which you can find for sale) or the >> old-time keelboats (not likely to be a major article in commerce >> today). > > Propelled by a manual device? :) > > Re-reading Martin's descriptions I see another problem with paddle > surfboards - the paddle is one-sided, so (if modelled) would these > be a subclasses of canoes... therefore boats (unlike kayaks)?! > > Barry >
