Thomas,
I agree and think that is the right mapping for ISBN13.

Thank you everyone for your answers!
About ISBN there are in the Freebase dump:
- 698735 triples with media_common/cataloged_instance/isbn13
- 692557 triples with book/book_edition/isbn
So, I think we may just ignore book/book_edition/isbn and map media_common/cataloged_instance/isbn13 to P212. What do you think about it?
I have only added the most used 1000 properties in order to don't hide important properties with less important ones. But feel free to add properties that are not listed there. I've just added to the page properties for chemistry: https://www.wikidata.org/wiki/Wikidata:WikiProject_Freebase/Mapping#Chemistr...
Cheers,
Thomas

Egon,
Chemistry has some very good bits of data in regards to SMILES property in Freebase, btw I did some of that editing work in Freebase myself long ago ! :)
Also the Chemical Classifications are pretty useful as well, I would say, but would need careful review work upon importing into Wikidata. Here's a nice view of the Chemical Classifications https://www.freebase.com/chemistry/chemical_classification?instances=

Dear Thomas,
I am personally interested in the chemistry bits, and checked the list, but did not see the "chemistry" domain from Freebase:
https://www.freebase.com/chemistry/chemical_compound?schema=
Is that just a matter of timing, or is it left out because WP/WD already has a good coverage?

Hey everyone,
As you may already know, I am currently working on the importation of Freebase content into Wikidata [1] using the primary source tool [2].
One of the big challenges of the migration is to build a good mapping
of the
properties of Freebase to Wikidata ones.There are a few thousand of properties so it is a task too big to be done alone. Your help is far
more
than welcome for this task on this page: https://www.wikidata.org/wiki/Wikidata:WikiProject_Freebase/Mapping
Cheers,
Thomas
