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.
1. 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.
2. 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...
