Hoi,
With the recent introduction of federation for DBpedia, it is possible to
have queries for the DBpedias for a specific language and Wikidata. I have
blogged how we can make use for this [1].

It makes it much easier to compare Wikidata and DBpedia and when we take
this serious and apply some effort we can make a tool like the one by
Pasleim [2] for Wikipedias that do not have a category for people who died
in a given year.
Thanks,
GerardM

Hi, a few clarifications from my side
A more up-to-date link for the data is here: https://gist.github.com/
jimkont/01f6add8527939c39192bcb3f840eca0
and this dump was not generated with federated queries, as this was not
possible at the time of creation but with a simple script

it is meant only as a proof-of-concept project that showcases differences
in birthdates between Wikidata, Dutch Wikipedia and Greek Wikipedia as
extracted in the DBpedia 2016-04 release, (which also means that it is
based on ~1y old data)

Best,
Dimitris
