Secondly, we'd like to contribute (or enable the Wikidata community to contribute) the data that we've already extracted from WP infoboxes back to WikiData. I'm not quite sure what the best way to do that is (pull by the community is probably better than push by Google) but having the linkages between equivalent concepts is an important first step to sharing more data.

Hi Shawn,
I have a couple of questions:
1) How do you store the provenance of the data? Which method do you use for sourcing your statements?
2) If the licenses for the data are mixed, how is it possible to know which data is CC0 and which CC-BY?

Cheers,
