Patrick, So, perhaps one day it will be a standard, but not today. Good catch! Did you join the Pedantic Web [1] group, yet? We need more people like you. Hope you are nearing a great weekend! Yes, indeed, I plan to go to DERI FAWM now and allow my brain to be off-line till 15:00 U

It was the the claim that /.well-known/void is "a standard" that I was surprised by. It's the sort of thing that could easily be on a Rec track somewhere, I just wasn't aware of it. Sorry if I somehow gave the impression that VoID is a W3C Recommendation. I would consider it as a de-facto

Probably VoID metadata/dataset URIs will be easier to discover once the /.well-known/void trick (described in paragraph 7.2 of the W3C VoID document) is widely adopted. greed. But it's not a 'trick'. It's called a standard. Is it? Yes, I think that RFC5785 [1] can be considered a standard

Welcome. Hopefully not muddying the water… We use (like many, I think) a voiD URI to identify our datasets, for example http://oai.rkbexplorer.com/id/void This does the standard content negotiation, try: curl -i -L -H "Accept: application/rdf+xml" http://oai.rkbexplorer.com/id/void (The -i will s

So, does this mean that the URI of the dataset (DBPedia) is http://lod-cloud.net/dbpedia? ? It is one URI identifying the DBpedia dataset, yes. It is likely not the authoritative one as it is not int the dbpedia.org namespace, so there may be others ... Cheers, Michael -- Dr. Mi
