Not viewing dbpedia:France resouce #5

Closed gatemezing closed 12 years ago

gatemezing commented 12 years ago

Hi, First of all this is a cool stuff for visualization. I was playing a bit today, but at some point it was not possible to load this page: http://dbpedia.org/resource/France; althought I can retrieve the .ttl file. Is it a matter of encoding?

Again, great job!

Best, Ghislain

Ghislain, thanks for reporting this. I can see the problem here (on a demo instance): http://semanticreports.com/?uri=http%3A%2F%2Fdbpedia.org%2Fresource%2FFrance I will look into this.

Ghislain, it's seems to be a problem with DBpedia - RDF/XML serialization of http://dbpedia.org/resource/France contains no real metadata about the resource, only owl:sameAs and some redirection properties.

In other words, statements with http://dbpedia.org/resource/France as the subject are missing, only "backlinks" are present where it's the object. Take a look at http://dbpedia.org/data/France.rdf and compare it with http://dbpedia.org/data/Denmark.rdf, for example.

Hello.. I don't really understand this issue.. So when I run this query "select ?p ?o where { http://dbpedia.org/resource/France ?p ?o} " here dbpedia, the result is not meaningful for Graphity? Would it be better to use dbpedia fr instead?

Best, Ghislain

Yes you can use the DBpedia SPARQL endpoint via Graphity: http://semanticreports.com/sparql?endpoint-uri=http%3A%2F%2Fdbpedia.org%2Fsparql&query=SELECT+DISTINCT+*%0D%0A{+%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FFrance%3E+%3Fp+%3Fo}

However if you directly access Linked Data resource about France, it will not show anything, because for some reason, DBpedia's RDF/XML description is missing the main metadata (as explained before): http://semanticreports.com/?uri=http%3A%2F%2Fdbpedia.org%2Fresource%2FFrance

Compare it with Denmark, for example -- all the metadata is there: http://semanticreports.com/?uri=http%3A%2F%2Fdbpedia.org%2Fresource%2FDenmark

OK. Please could you forward this issue in the dbpedia mailing list? Or you prefer that I do it ?

namedgraph commented 12 years ago

Yes, please do that :) I'm not in touch with the DBpedia guys.
