But isn't one of the key ideas behind RDF that we *give* these things (network non-addressable resources: NNARs) URIs and can then start to describe them. The idea of DBpedia.org is that it automatically gives us a URI for the concept behind every page at Wikipedia. That is, while <http:// en.wikipedia.org/wiki/The_Waste_Land> is a URI for a web page discussing a poem by T S Eliot, <http://dbpedia.org/resource/ The_Waste_Land> is intended to be a URI for the poem itself - the NNAR. (See <http://wiki.dbpedia.org/Datasets#h18-4>.) For any (English edition) Wikipedia article X, the following triples hold (or such is the aim of DBpedia.org). @prefix res: <http://dbpedia.org/resource/> . @prefix data: <http://dbpedia.org/data/> . @prefix page: <http://dbpedia.org/page/> . @prefix wiki: <http://en.wikipedia.org/wiki/> . @prefix foaf: <http://xmlns.com/foaf/0.1/> . @prefix dc: <http://purl.org/dc/terms/> . data:X foaf:primaryTopic res:X ; dc:source wiki:X . page:X foaf:primaryTopic res:X ; dc:source wiki:X . wiki:X foaf:primaryTopic res:X . res:X foaf:page wiki:X . That is, DBpedia.org assigns URIs for every concept that has an article on Wikipedia, which is a separate URI from the article itself. MySpace or its ilk could easily do something similar by creating a subdomain res.myspace.com such that for any user X at MySpace, then: @prefix myspace: <http://www.myspace.com/> . @prefix myres: <http://res.myspace.com/> . myspace:X foaf:primaryTopic myres:X . myres:X foaf:page myspace:X . Then someone could easily make statements like the one mentioned earlier: myres:joe foaf:knows myres:some_band . The solution is not to find easier ways to make statements about things without URIs, but rather we should have more URIs for NNARs. -- Toby A Inkster <mailto:mail@tobyinkster.co.uk> <http://tobyinkster.co.uk>
