Hello,

[think this come up before, but can't find a recent thread that directly relates to this]


Are there any plans directly relate entities in Wikidata with categories in Wikidata – and avoid the duplication between all the different page languages?


For example this book:
http://www.wikidata.org/wiki/Q3235393
http://en.wikipedia.org/wiki/Half_of_a_Yellow_Sun

And the English Wikipedia page is a member of this category:
http://en.wikipedia.org/wiki/Category:War_novels

Which has this Wikidata ID associated with it:
http://www.wikidata.org/wiki/Q8170055


Currently we could resolve it using the following, slightly convoluted workflow:
  1. Get Wikidata ID and resolve to 1 (or more) Wikipedia language pages
  2. For each Wikipedia page, lookup a list of categories and gather together
  3. From each category lookup a Wikidata ID for that category page
  4. Remove duplicate Wikidata IDs
  5. Lookup each of the Wikidata IDs in Wikidata to get title/description
Going from a Wikidata Category to a list of Wikidata entities could be done in a similar way.

Is there a better way of doing this now or the near future?
