@Andy
It seems to me that, before the dats can be imported, we'll need to add
several new Wikidata properties. Was that your intention? Run multiple times my mapping script from Freebase to Wikidata is easy so I think I'll run it again as soon as the mapping is really improved and add the added statements to Primary Source. So, yes, feel free to start the property creation process. I'm still at Google for 8 weeks so we have time to go throw the property creation process.
Depends -what is the overlap between the two sets of items described by
those triples? As Thad said most of the ISBN 13 set in book/book_edition/ISBN have been moved into media_common/cataloged_instance/isbn13 so I believe only import media_common/cataloged_instance/isbn13 is a first good step even if we miss some data. I believe that there are so many more triple that are more important to import than these missed ISBNs. But if someone propose a good way to import them too I am ready to implement it.
@Marco Thank you very much for the links to these discussions. I was not aware of them.
- Are these mappings [1, 2] coming from earlier discussions [3] already
validated/integrated? Not yet, but I plan to integrate [1] into the mapping with a human validation. For [2] I currently don't do anything related to types but it may be something interested to do if I have time.
- As the maintainer of the DBpedia mapper bot, the procedure to add
schema mappings to Wikidata classes and properties has already been discussed [4].
The bot code can be easily adapted for Freebase, let me know and I can
volunteer to open a request for the new bot. Thank you very much! It would be very nice to do so. Yes, please, open a such request.
About these mapping I have made a property proposals for a "subproperty" [4] and a "subproperty of" [5] properties in order to have something less strict than "equivalent property" for mappings.

Yeah, I noted that too. I think this should be discussed in the Wikichemistry project, and we should also look at what Marco sent around...
