Hi!
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
Some of these look a bit challenging due to different semantics. I.e. https://www.freebase.com/award/ranking/year probably matches point in time (P585) but the former is for specific awards, while the latter is a generic property that would be applied to the award claim. So it's not 1-1 transition. Would it still be useful to match P585 to https://www.freebase.com/award/ranking/year and do the same in similar cases? I.e. pretty much all /year ones would be P585, but in different context.
