Thanks Stas, So, hmm...we'd have to build our own parser or something is what your saying ? Because Wikidata doesn't have those kinds of connections in its graph and also doesn't have a SPARQL service yet against the Wikipedia API:Categorymembers https://www.mediawiki.org/wiki/API:Categorymembers to deduce those subcategories, right ?
How difficult is it for someone to create a service like the LabelService , but instead using the WP Categorymembers API ? Or do you have some other ideas ?
