@nasser @jleedev @darius right; I'm actually kinda curious about the difference between "all the stuff JSON-LD is capable of as a standard" vs "the way JSON-LD gets used by ActivityPub and its implementations"

I get the feeling that the latter is a lot more just "a document with hyperlinks" and the ontology stuff doesn't really come into play in a serious way, but maybe I've just been looking in the wrong places
