If such doesn't exist then 406 will do. I want to get at the RDF data without exercising my eyeballs :-) At a higher level (i.e. RDF aware User Agent) here are the results of your current URIs: 1. http://demo.openlinksw.com/rdfbrowser/?uri=http%3A%2F%2Fbudapest.rkbexplorer.com 2. http://demo.openlinksw.com/rdfbrowser/?uri=http%3A%2F%2Fnsf.rkbexplorer.com%2Fid%2Faward-0211606 Kingsley > [rover:~] hg% curl http://nsf.rkbexplorer.com/data/award-0211606 > <?xml version="1.0" encoding="UTF-8"?> > <!DOCTYPE rdf:RDF [ > <!ENTITY rdf 'http://www.w3.org/1999/02/22-rdf-syntax-ns#'> > <!ENTITY rdfs 'http://www.w3.org/2000/01/rdf-schema#'> > <!ENTITY owl 'http://www.w3.org/2002/07/owl#'> > <!ENTITY akt 'http://www.aktors.org/ontology/portal#'> > <!ENTITY akts 'http://www.aktors.org/ontology/support#'> > <!ENTITY extn 'http://www.aktors.org/ontology/extension#'> > <!ENTITY wiki 'http://resist.ecs.soton.ac.uk/wiki/'> > <!ENTITY resist 'http://resist.ecs.soton.ac.uk/ontologies/resist#'> > <!ENTITY resex > 'http://resist.ecs.soton.ac.uk/ontologies/resilience-mechanisms#'> > <!ENTITY courseware 'http://www.resist-noe.org/ontology/courseware#'> > <!ENTITY dc 'http://purl.org/dc/elements/1.1/'> > <!ENTITY dct 'http://purl.org/dc/terms/'> > ]> > <rdf:RDF > xmlns:rdf="&rdf;" > xmlns:rdfs="&rdfs;" > xmlns:owl="&owl;" > xmlns:akt="&akt;" > xmlns:akts="&akts;" > xmlns:extn="&extn;" > xmlns:wiki="&wiki;" > xmlns:resist="&resist;" > xmlns:resex="&resex;" > xmlns:courseware="&courseware;" > xmlns:dc="&dc;" > xmlns:dct="&dct;" > > > <owl:Ontology rdf:about=""> > <dc:description rdf:datatype="&xsd;string"></dc:description> > <dc:title rdf:datatype="&xsd;string"></dc:title> > <dc:created>ReSIST Project</dc:created> > <dct:created rdf:datatype="&xsd;dateTime">2007-11-06 > 19:48</dct:created> > <rdfs:label rdf:datatype="&xsd;string"></rdfs:label> > <dc:source > rdf:resource="<http://nsf.rkbexplorer.com/id/award-0211606>"/> > </owl:Ontology> > <rdf:Description > rdf:about="http://nsf.rkbexplorer.com/id/award-0211606"> > <rdf:type rdf:resource="akts:Temporal-Thing"/> > <rdf:type rdf:resource="akt:Project"/> > > <akt:has-web-address>"http://nsf.gov/awardsearch/showAward.do?AwardNumber=02 > 11606"</akt:has-web-address> > <akt:has-title>"WORKSHOP:Database and Information Systems Research > for Semantic Web and Enterprises"</akt:has-title> > <akts:has-time-interval>_:b1</akts:has-time-interval> > <akt:has-project-leader > rdf:resource="http://nsf.rkbexplorer.com/id/person-0782e218c1a2c8d808c2040f3 > 315e8e1"/> > <akt:has-leading-organization > rdf:resource="http://nsf.rkbexplorer.com/id/organization-d9591936c073da7ee9b > d45da9e8cec1e"/> > <akt:has-funding > rdf:resource="http://nsf.rkbexplorer.com/id/grant-0211606"/> > </rdf:Description> > </rdf:RDF> > > > -- Regards, Kingsley Idehen Weblog: http://www.openlinksw.com/blog/~kidehen President & CEO OpenLink Software Web: http://www.openlinksw.com
