Re: User contributed data to DBpedia, was: [ANN] Add your links to DBpedia workflow version

Sebastian, I am so glad you said that!
I already think (as I have said on the list before) that links and stuff should not be part of "dbpedia" - when I access dbpedia I am expecting stuff that came out of wikipedia - no more than that.
It therefore comes with all the trust (!) and provenance of that source.
Adding even links that are not clearly marked as a different source is very suspect.
Adding extra "correcting" information would be a Bad Thing.
Correcting the information in wikipedia is the usual way to go.
Or, it might be sensible to extend your excellent idea of the github resource to provide information such as dbpediaURI-linked RDF.
But I'm not sure why that would be useful, as the data is presumably already somewhere else.
So it is more an index of where dpbepdiaURIs are used (and Sindice does a lot of that).

When it comes to hierarchy (and instance/class descriptions, although I don't think they are useful), I think the same thing applies.
Can Wikipedia be enhanced to include the information? If not, then any such enhancements over dbpediaURIs should be clearly separated from the main source.

Best
Hugh

We really do not want to become something like Freebase, as DBpedia should stay a Semantic Web mirror of Wikipedia. By the way, wouldn't it be sufficient to link to EuroStats?

This should, however, not overlap with the DBpedia ontology. There are also plans to extend the Mappings Wiki, so everybody can customize mappings for personal use cases. This is not an easy topic however.
