Hi Gerard and all,

Hoi,
Congratulations on the new version of DBpedia :) .. This makes it an auspicious occasion to talk about future collaboration.
At this time several Wikimedians are busy harvesting data from Wikipedia and loading it into Wikidata.
Yes, we did see this and of course all these Wikimedians are more than welcome to reuse parts of our code for building their harvesters (the DBpedia extraction framework does a lot of little things around data cleaning and recognizing different variations of values as well as normalizing units of measurements that I guess would also be useful for the other harvesters.)
You are harvesting data from Wikipedia and loading it into DBpedia. As we are including data into Wikidata, it goes into DBpedia as well... We might as well work together on this.
One of the best parts (as far as I am concerned) is your knowledge of fields used in infoboxes and knowing how they are the same / related to fields in other infoboxes. This expertise should be easy to absorb into Wikidata
Yes, all the information about the infobox to ontology mappings are maintained by the DBpedia community in the mappings wiki (http://mappings.dbpedia.org/index.php/Main_Page) and of course Wikidata is more than welcome to use them.
As far as I know the mappings wiki also already contains mappings from DBpedia classes/properties to the corresponding Wikidata classes/properties for about 1/3 of all classes/properties (Sebastian Hellmann cc’ed knows more about this). So it would be very simple for you to use the mappings to fill your repository.
In Wikidata we use qualifiers, will you adopt qualifiers in DBpedia? At this time qualifiers are not handled by the harvesting software I am familiar with.
What kind of qualifiers? Do you mean provenance information?
To me these are the two issues that determine how easy it will be to effectively collaborate on great content for Wikidata. To me the most important aspect of Wikidata is that it is actually used. Information added becomes available in many places. Consequently more data for Wikidata, data that fits in well and is closely related to the 100+ wikipedias you are harvesting will ensure a rich experience in so many places.
Yes.
Cheers,
Chris
Thanks,
GerardM

I do know how much the DBpedia people want to reach out and connect in any positive way with both Wikipedia and Wikidata.
I have no knowledge (on the DBpedia side) of any resistance to collaborate with Wikidata. We've always seen this effort (like other structured data efforts of this kind e.g., Freebase, YAGO etc..) as being mutually beneficial.
