Hi André,
I just made a small counting program with Wikidata Toolkit to count unique references. Running it on the most recent dump took about 30min. I uploaded the results:
http://tools.wmflabs.org/wikidata-exports/statistics/20150831/reference-coun...
The file lists all references that are used at least 50 times, ordered by number of use. There were 593778 unique references for 35485364 referenced statements (out of 69942556 statements in total).
416480 of the references are used only once. If you want to see all references used at least twice, this is a slightly longer file:
http://tools.wmflabs.org/wikidata-exports/statistics/20150831/reference-coun...
Best regards,
Markus

Hi all!
I'm wondering if there is a way (SQL, api, tool or otherwise) for finding out how often a particular source is used on Wikidata.
The background is a collaboration with two GLAMs where we have used ther open (and CC0) datasets to add and/or source statements on Wikidata for items on which they can be considered an authority. Now I figured it would be nice to give them back a number for just how big the impact was.
While I can find out how many items should be affected I couldn't find an easy way, short of analysing each of these, for how many statements were affected.
Any suggestions would be welcome.
Some details: Each reference is a P248 claim + P577 claim (where the latter may change)
