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

Hi Søren,
(I renamed the topic and replaced DBpedia developers list with discussion)

in general, we would like to improve nothing in DBpedia, whcih should be 
fixed in Wikipedia. So population numbers should be fixed there (or 
WikiData soon hopefully). 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?

On the other hand, it might make sense to create additional structures 
over DBpedia identifiers. Yago, umbel and schema.org already does this 
and provides their hierarchy for DBpedia to include. 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.

Another idea: When linking DBPedia administrative regions to NUTS codes I sometimes see population numbers in the DBPedia resources, but they are of low quality. I can provide the newest Eurostat numbers for them. And again; what should the predicate be?

Best regards,
Søren Roug

||
|| I'll contribute some links to a vocabulary of NUTS codes. The Nomenclature of
|| Territorial Units for Statistics [1] is a hierarchial organisation of
|| administrative regions in Europe. It is heavily used by Eurostat, and LOD2 has
|| converted the Eurostat datasets to RDF.
||
|| The word hierarchial lead me to my question. Would it be useful to contribute
|| links to DBPedia that link two DBPedia resources together in a hierarchy, and
|| what should the predicate be? SKOS broader/narrower seems to me to have
|| too
|| little semantic information about what kind of relationship it is. I.e. that
|| it is a spatial form of broader/narrower.
