You are correct. I was talking about category namespace in Wikidata
Query Service. It is documented here:

Hoi,
No. There is no such thing as "category namespace" in Wikidata. There are
items for categories. They are related to other categories through the
interwiki links but they are not linked in any other way to other queries.
The data from categories is harvested but not consistently so. When you
define what to expect in a category you will find that when you query
Wikidata, Wikidata has different items because it has more relevant items
and, there are items in the query that have not been categorised in the
category.

No, there is nothing special about categories. If anything, through queries
we can maintain the categories as well. That would be a boon for our
readers.
Thanks,

Okey,
Just checking so let's say for:
https://www.wikidata.org/wiki/Q2201
Narrative location (NY City) is from English Wikipedia, then it's CC BY SA?
Thanks!

No, it's CC0 since it's Wikidata data. Facts as such are not
copyrightable, so the fact that the particular movie is set in NYC is
not subject to any license. Specific arrangement (collection) of facts
can be copyrighted and licensed though and this specific one is
Wikidata, which is licensed under CC0.

Data in the main namespace, without the use of federation - yes.
Federated data - https://query.wikidata.org/copyright.html, federated
endpoints can have different licenses, either CC0-like or CC-BY-SA like
(I don't think we accepted any that have anything stricter than that)
Category namespace - since it comes from Wikipedias, it's CC-BY-SA I
assume.

All namespaces except Item and Property are CC-BY-SA.

So yes, all data that can be fetched throught SPARQL is CC0.
