[Fediverse BackUp]

Could an ActivityPub / ActivityStreams file be a "good" format for backing up a post?

(I.e., what I call an "Activity File". I.e., the file that has a media-type of "application/activity+json".)

[Fediverse BackUp]

I think one challenge, in practice, with using an Activity File as a BackUp Format is that — a lot of Fediverse software does NOT embed (non-text) media (such images, audio, video, etc) in the Activity File.

But, instead references them using URLs.

(And, by "URL" I mean "URI", "IRI", etc.)

Usually this is probably a good thing, but —
