Hi Ian, IMH, newbie O, this is good and useful stuff. I really appreciate the human-friendly URIs. You asked for feedback, so here are some issues I ran into: 1) The web service response does not have a URI (e.g. the CC:SuccessfulReply in http://www.pipian.com/rdf/places/country/Asia), so it's not straightforward to find statements about it. <CC:SuccessfulReply> <CC:inReplyTo> <CC:Request> <dc:subject> <wail:Place> <wail:name>Asia</wail:name> <dc:type>continent</dc:type> </wail:Place> </dc:subject> </CC:Request> </CC:inReplyTo> <rdfs:seeAlso rdf:resource="#Asia" /> </CC:SuccessfulReply> 2) When I dereference a continent, region or planet URI in one of the pipian namespaces, I get a number of statements about that URI, and my (forward-traversing) app is happy. However, when I dereference a country or subdiv (for instance, <http://www.pipian.com/rdf/places/country/AZ#AZ>) I get statements about a different URI with an owl:sameAs edge to the original URI: <urn:iso:3166-1:AZ> owl:sameAs <http://www.pipian.com/rdf/places/country/AZ#AZ> <http://www.pipian.com/rdf/places/country/AZ#AZ> rdf:type rdfs:Resource The point is that most of the information I get back is about <urn:iso:3166-1:AZ> instead of the handy HTTP URI. Why not turn the owl:sameAs around and make statements about <http://www.pipian.com/rdf/places/country/AZ#AZ> instead? 3) The graphs you return contain a lot of what seem to me to be unnecessary, redundant statements (for instance, statements about Asia in the graph about Azerbaijan). If I want information about Asia, I can just dereference Asia's URI. 4) I noticed a circular owl:sameAs statement in each country and region graph, dunno about other types. I also don't know whether it matters. <http://www.pipian.com/rdf/places/continent/Asia#Asia> owl:sameAs <http://www.pipian.com/rdf/places/continent/Asia#Asia> 5) The namespace declaration for the SWEET Space ontology is missing a '#', which breaks a few URIs: xmlns:sweet = "http://sweet.jpl.nasa.gov/ontology/space.owl" Josh
