Lady, EVOLVED 
@Lady "It is very unclear why some·one would ever want to make their personal finances a part of the Semantic Web, [...]" I agree, and yet Venmo seems to keep trying to make it happen.
Anyway, a neat collection that I should probably consult for some projects. Thanks for sharing!
@aschmitz i have beef with ActivityStreams, which is otherwise quite popular, is probably the biggest thing to be aware of; disregarding the rest of the model, its Collection classes are quite heavily used and i’m still undecided whether i personally want to draw on them or lean on more oldfashioned approaches
@Lady Fair. I'm more thinking of metadata to tie to mostly-discrete things, like physical objects, though in some cases probably podcasts and possibly music.
@Lady Yeah, without profiles I'm mostly thinking of it as a place to go check for the "most[ly] reasonable" source for a given piece of information, rather than trying to fumble through whether DC has it, and then whether it's specified well or if I have to go looking elsewhere, etc. (Though I guess I don't know the extent to which you've chosen less popular systems for some things because you've decided the popular ones are insufficient in some cases - that could be a bit tricky to balance.)
