Thanks! I assumed it was open but wanted to ask first (I've not participated in the Wikimedia community for a couple of years).
Well spotted! Yes, this is broadly connected to POSI. Though this isn't the first time we've thought of Wikibase. I and other Crossref people, have been at WikiCites past.
Thanks very much for the stats and links. Those Wikidata numbers uncannily mirror ours.
Cheers
Joe
