Class mappings are almost complete Kingsley. We were trying to get Wikidata
to the point where it is easy for folks to do trivial queries right inside
WDQS as part of WD Goals for 2016.

Hello team :)
So while I'm helping with the Wikidata -
Schema.org mappings, a request
came in to expose subcategories of an existing Wikipedia category.
For example, say I start with this topic:
https://www.wikidata.org/wiki/Q27119725 Parking facilities
The topic's main category is shown as "Category:Parking facilities" and
that has links to Wikipedia, specifically a Wikipedia category link, and
where the WP category page has subcategories that I would like to expose
somehow in whichever way is *easiest* currently with our tools, apis, etc.
Can it all be done in SPARQL against some services that already expose WP
subcategories given a specific category ? Or is there an API that does
this already ? other tools that might expose WP categories ?
The IDEAL GOAL is to query 'equivalent class' =
schema.org/ParkingFacility
and get back the WP categories *in one shot or query or api call.*
http://schema.org/ParkingFacility
-
Parking facilities in India
<https://en.wikipedia.org/wiki/Category:Parking_facilities_in_India>
- Parking facilities in the United States
<https://en.wikipedia.org/wiki/Category:Parking_facilities_in_the_United_States>
- Aircraft hangars
<https://en.wikipedia.org/wiki/Category:Aircraft_hangars>
- Garages (parking)
<https://en.wikipedia.org/wiki/Category:Garages_%28parking%29>
- Railway depots
<https://en.wikipedia.org/wiki/Category:Railway_depots>
Any gurus ?
Hi Thad,
If there are owl:equivalentClass mappings in some Linked Data Space, and
the SPARQL service associated with said Data Space supports
owl:equivalentClass reasoning, then the answer to your question is yes.
What unknown right now is the class mappings between Wikidata and
Schema.org. If a dump of those exist, the rest is trivial :)
