@NEETzsche @lain @Moon my instinct tells me that "object" here means object on the network, and URL is just a way to identify an object, since there is no universal way to refer to an object apart from an URL, and it's most likely expected that URL is something instances can "recognize", i.e. "instance.fedi/posts/1" is a post on that server and that server can respond with its data.

>hey instance.fedi can you tell me about instance.fedi/posts/1
<sure fam, here's a json

>hey funkwhale.fedi can you tell me about funkwhale.fedi/audio/rickroll.mp3
<sure fam here's a json

>hey legit.mp3forfree.ru can you tell me about legit.mp3forfree.ru/downloads/sandman.mp3
<what :what:

I might be wrong but I think that's the intention here.
