I have difficulty in interpreting what you say - we are looking at the same "linked data browser" page?: http://ec2.monrai.com:8890/facets/ All I can see is a page that says: "Lookup things named "" " So the only possibility of linked data browsing is to put in something with a name. So I put something topical in (from this list). Since I see ... <Station rdf:about="http://ontologi.es/rail/stations/gb/MAN";> <foaf:name xml:lang="en">Manchester Piccadilly</foaf:name> ... I try "Manchester Piccadilly" and get some response, but nothing leads me to http://ontologi.es/rail/stations/gb/MAN.rdf or any of the data I find there. Similarly topical from this list, I find no way of browsing http://foaf.qdos.com/lastfm/people/keithalexander#me or getting to that page by searching for "Keith Alexander".
I also see no way of doing "3. Raw URI Lookup" of this URI. I assert that if this is a "linked data browser", then since http://ontologi.es/rail/stations/gb/MAN.rdf conforms (I think) to "How to Publish Linked Data on the Web", then I should be able to browse it using the browser. If I can't, then it is not a "linked data browser". Of course, this browser is very capable of browsing your excellent single site, but that is not the same thing, I am sorry to say. Best Hugh PS Thank you for pointing out this is not in EC2. I have difficulty working out what is in the cloud and what is not, as it appears to be opaque, which I think is the idea.

For starters, this isn't an EC2 hosted instance. Its a huge Quad Store with 4.5 Billion+ (and counting) triples. You find entities and their descriptions via: 1. Full Text Search Patterns 2. Entity URI Lookup by Label 3. Raw URI Lookup There is a Tab for each. When you find an entity and open up its description, you can click on "Statistics" to explore other relationships and/or how we've handle owl:sameAs, IFPs etc.. If the above, don't get you where you want to be, then you can also start from the VoiD graph at: http://lod.openlinksw.com/void/Dataset. And of course, if all fails, you can simply use the SPARQL endpoint at: http://lod.openlinksw.com/sparql . If data is missing simply give me an example of a query that works in your data space and we'll look into why its missing in ours.
