Thanks Tim, good questions. Sorry the questions were necessary. For example, if you go to http://nsf.rkbexplorer.com/ You will find the Browse and Query buttons on the top right, and in the text. So put in Berners in the browse box. You get some matches. The top one is http://nsf.rkbexplorer.com/id/person-6092a2a72319fc9437583fb2d04733ea Which (I hope) 303s in the browser to an html page that has two instances of you that have been identified as the same (we are doing the co-referent analysis ourselves, as the existing resources cannot in general be trusted, and then pollute things). Seems the RDF target is broken at the moment - see below. It shows two projects you were involved with (again, hope they are right). If you want the full RDF that the triple came from (on their way to the triplestore), the Source column on the right has a link (>>) to the file. These can be quite large files, of course. Browsing for "Semantic Web" will get all sorts of things in cordis and citeseer (which includes ACM), although it takes a while on dblp for the rendering of the results. Here are some more randomish URIs: http://dblp.rkbexplorer.com/description/books/sp/GeroimenkoC02 http://southampton.rkbexplorer.com/id/eprints-13347 http://newcastle.rkbexplorer.com/description/person-4 There isn't really a starting point on any of the stores. Basically they are resolvable URIs and SPARQL, on top of which browsing can be built (as with the explorer we are developing). Hope that helps.
