hi, i was wondering what the most simple way to query multiple categories and intersections. the most simple application for e.g. GLAM is: search museums of modern art in the city of zürich. if i do not find enough i want to see all museums in the city of zürich. how and where i would query that information? another example would be barack obama: https://en.wikipedia.org/wiki/Barack_Obama, which has the categories: politicians from chicago, politicians from hawei, afro american politicians, afro american christians, afro american non fiction writers, and so on. basically all of them include: * location * profession * race * religion * awards in some combination. l was wondering how these categories can be matched with what is stored in wikidata: www.wikidata.org/wiki/Q76, or, e.g. query wikidata for afro-american politicians from hawei. happy new year btw :) rupert
