SDcat
Module to check whether local short description matches that on Wikidata

local p = {}

--[[
setCat has the qid of a Wikidata entity passed as |qid=
(it defaults to the associated qid of the current article if omitted)
and the local short description passed as |sd=
It returns a category if there is an associated Wikidata entity.
It returns one of the following tracking categories, as appropriate:
* Category:Short description matches Wikidata (ideally case-insensitive)
* Category:Short description is different from Wikidata
* Category:Short description with empty Wikidata description
For testing purposes, a link prefix |lp= may be set to ":" to make the categories visible.
