What I am looking for is an openly and collectively maintained DB a la wikipedia from which interface you could download all search hits as well-formatted, parsable lines in a text file without having to "click next", copy and paste, and all that kind of nonsense.
I could imagine someone in the corpora research community has taken the time to compile a database which IMO should include: ...
That sounds like a description of Wikidata; that is the kind of thing it was created to achieve, at least.
You can construct your own queries in SPARQL, which I've found quite hard, though I've not done much with it the past couple of years, so it may have got better.
The query builder will make it a bit easier: https://query.wikidata.org/querybuilder/?uselang=en It will still be a bit of work, finding out the property numbers for all the fields you want included.
(If you go down this route, and it works, maybe you can post back the SPARQL query you end up with.)
