Wikidata and Wikibase, the software it runs on, are expanding it into a "federated" network of knowledge stores. You can, for example, link from wikidata to some other instances of the software and query them transparently. It's used by a few museums that want to keep control over the description of the art, but link to wikidata for, say, the artists' place of birth. Then, you can use their query interface (SPARQL etc.) to get all the art they have from "artists born in a city that had a commercial port in 1960" without the museum ever having to enter more information than "this is a van Gogh".

EDIT: Here's an example from the EU, which has their complete budget in a triple store: https://query.linkedopendata.eu/#SELECT%20%3Fproject%20%3Fpr...

(you have to click the blue "play" button to run the query.)

I'm not sure if they are federating with wikidata or just importing the data, but the result is similar either way.

(For budgets, always go for the treemap: https://query.linkedopendata.eu/#%23defaultView%3ATreeMap%0A...)
