Cross-posting within ActivityPub

submitted by edited

Just wrapped up a session at FediForum where snarfed.org@fed.brid.gy and quillmatiq@mastodon.social discussed FEP-fffd: Proxy Objects as a way to link disparate cross-network objects together.

I piped up that rimu@piefed.social and I were working on similar problems with cross-posting, though we were discussing this well within the confines of ActivityPub — cross-posting between threadiverse communities

We hadn’t come up with any path forward yet, but the FEP notes some properties that we could use.

  • alsoKnownAs to refer to a canonical post?
  • An url array to show cross-posts?

I wouldn’t use alsoKnownAs since that’s typically for Actors and “people”, however you may want to look at the RDF sameAs property or something from a similar RDF space.

@julian @snarfed.org @quillmatiq @rimu This was above my pay grade. LOL but always fun listening to them and trying to figue out what the heck they are talking about!

@julian @snarfed.org @quillmatiq @rimu this is at the forefront of exciting fedi dev and I can't wait to see where this leads!
