Re: ANN: Nature Publishing Group Linked Data Platform
Hi Hugh: Many thanks for your comments. And to be sure, CC0 means exactly that - public domain - have at it. But I am wondering whether the use of owl:sameAs to a non-http URI is best practice in something that says it is Linked Data? We take a very pragmatic view on this. We completely support the Linked Data principles in using HTTP URIs to identify resources and also to provide descriptions. And we have done so in all our assignments. All our own named objects are dereferenceable. However, it is also true that there are a number of HTTP URIs which are non-dereferenceable and also non-HTTP URIs (non-derefenceable from an HTTP application context) which are used within certain domains of discourse and as such offer RDF link points. In our view there is much to be gained from adopting an open inclusive approach. It may be that some HTTP URIs later become derefenceable (and here I'm specifically thinking of the id.crossref.org domain URIs). Some other non-HTTP URIs (info:doi/ and doi:) have also been used historically and are still very well represented on the web (cf. Wikipedia articles, for example). In time these may be superseded by HTTP forms but for now the use of owl:sameAs affords a valuable bridging between different datasets. From an RDF perspective, dereference is a bonus, not a necessity. As for dumps of our datasets this is something that we are actively discussing and we are certainly very aware of the value of local hosting.

Can you perhaps advise? - I am after the owl:sameAs data. I'm really excited about being able to use the data.

While we don't have any problems in principle I would just note that this may not be the most efficient way to get the data and that we would end up paying for all the queries. Yes! That's my eternal concern about SPARQL endpoints. I know how expensive crawls are, across many dimensions. This is also why at the onset of the LOD project there was an agreed best practice re. publishing SPARQL endpoints and RDF dumps. In a sense, the cost of not having an RDF dump is a SPARQL crawl :-( I think that this certainly provides us with more impetus to take forward our discussions on making dumps available for each dataset. Am hoping you might be able to hold back awhiles till we can get a decision on that. Of course, you would have known by now if we crawled your endpoint wholesale. For now, I simply add your endpoint to SPARQL-FED demos, which works fine :-) Kingsley Cheers, Tony On 14/05/2012 11:55, Kingsley Idehenkide...@openlinksw.com wrote: On 5/14/12 3:53 AM, Hammond, Tony wrote: As for dumps of our datasets this is something that we are actively discussing and we are certainly very aware of the value of local hosting.
