Can you please clarify what's missing?

Thanks for adding me in the loop! @RazShuty, do you mean any of this?

• migrate the existing reconciliation service (https://tools.wmflabs.org/openrefine-wikidata/) to work on any Wikibase install
• create a Wikibase extension that already provides a reconciliation API natively, without having to create a wrapper like I did

*anything else?

I think this ticket can be closed given that we cannot figure out what it is supposed to be about.

For reference, https://github.com/wetneb/openrefine-wikibase works for arbitrary Wikibase instances now (the first bullet point in my reply above).
