I’ve been disconcerted lately to find that the Discourse team appears to be putting the activityhub plugin on the backburner.

There are quite a few issues and rough edges. It would be good to know more about future plans, if there are any. There may be people interested to work on furthering federation of Discourse in some form or other. See below. I created this thread on SocialHub, so it federates out to Discourse Meta and the broader fediverse.

The current maintainer seems to be @pmusaraj

I have tried contacting Angus (the maintainer of the official plugin) on the Discourse meta forum

I can CC @angus here, as he is also a SocialHub member (and this will also carry over to Discourse Meta as another mention, I think).

Very nice! Are the changes intended to be PR'ed to the Discourse AP plugin, or will this be an independent project?

- It makes each federated category/tag behave much more like a real Lemmy community (Group actor), including its moderators, featured posts, follower rules, and shared inbox.
- A Discourse topic can be sent as a Lemmy-compatible Page (with replies as Notes), rather than only the formats upstream offers.
- Votes federate: remote upvotes/downvotes become Discourse likes, and the federated score is shown on posts.
- Moderation federates in both directions: removals, bans, locks, moderator changes, reports, and featured/pinned posts can be communicated to compatible remote communities.
- Discourse users become proper, followable ActivityPub people. Mentions are also resolved for federation.
- It can follow a remote community—for example on Lemmy or NodeBB—and present it inside Discourse as a local “shadow category.” Local users can then read and participate from Discourse.
- It adds an instance-level actor and optional “authorized fetch,” which can require signed ActivityPub requests when other servers retrieve content.
- Administrators get extra tools: community/federation health view, remote-community management, per-community ban management, URL/content resolution, and bulk republishing/backfill.

Have you discovered any interoperability issues?

Perhaps there is a better way to express it.

In my experience, group federation works well in Discourse. Most of the bugs that we identified during the test drive at SocialHub have been fixed.

I can name only one major issue that still remains, incorrect timestamps in old threads: https://meta.discourse.org/t/activitypub-plugin/266794/487

Too much going on irl atm, hope to find the time (and mostly concentration!) to test and publish it.
