@angus @how Can you maybe also activate it for @wordpress and maybe add me as admin? So that I can run some tests?
thanks to work by @pfefferle Wordpress should now federate properly with Discourse
@how would you be willing to try and follow my WordPress account (@laurenshof@fediversereport.com) from the Fediverse Report Category on the Social Hub? This way only my weekly article should pop up in the category, which I think fits well, and would be a nice benefit!
Thanks all!

Just a note that Iâve been testing wordpress-activitypub 2.3.1 with discourse-activity-pub locally and it works!
The Wordpress plugin is not yet ingesting Notes/Articles inReplyTo as comments yet though. @pfefferle This is what an object inReplyTo might look like

Perhaps the issue is that you donât support the ingestion of Announcements of an Actor (e.g. a Category Group actor) of an Activity (e.g. a Create Note of a Person inReplyTo the Wordpress Note)?

Thanks for debugging! This is a wild implementation! They do not send the reply directly, but instead an Announce of it!
Have to see how I can implement that properly!
Thanks! Lmk if I can help in any way.
Yeah, itâs an implementation of FEP-1b12
In short this lets people follow a taxonomy (e.g. a category or tag). The announcements come from the category (or tag) actor which is a Group.
We may add Person (user) following down the track in the Discourse plugin, however in a forum environment, following a taxonomy tends to make more sense than following a user. e.g. you probably want to know whatâs happening in Threadiverse Working Group as a category rather than just which topics I post there

Thanks @angus !
You are directly working on that plugin?
I understand the point and advantage of Announcing Activities (we do that also for WordPress. The blog-user Announces the posts of every blog user, and we also want to add support for Tags/Categories), but I havenât seen it for replies until now.

Yes, I built (am still building) the Discourse ActivityPub Plugin on contract for CDCK, the company that makes Discourse. I also maintain the WP Discourse plugin for CDCK, so I have some experience with Wordpress if that becomes relevant at any point.
Actually, testing your plugin this morning I was trying to remember why we Announce replies as well as the OP. I think it might have been a âstrictâ implementation of FEP-1b12, however Iâm wondering whether itâs necessary.

I will run some more tests and release a new version with comment support then!

Very exciting! Thanks for adding announce support.

@pfefferle I also had a look at federation between Lemmy and Wordpress. There is a minor fix I have to get in to make comparison of response content-type headers case insensitive (because you send charset=UTF-8 while eg Mastodon has charset=utf-8.
With that change I can already fetch Wordpress groups and users. But there is one more problem, Lemmy expects to find the Group that a post belongs to in cc or audience field. Is there any chance you could add that?

@nutomic I am more than happy to add anything that helps with interoperability!
The main issue with that is time! Itâs hard to have a local version of every platform, to be able to debug things.
So long story short: If you tell me what to do, I will do
Is there a preferred way to add the group? cc or audience?

Thanks for your help btw!!!

audience is preferable as its also where nodebb and discourse send it. Plus its easier to parse a single value than extracting from an array.

Yes, the Discourse plugin will resolve object URIs

Interesting look at how #activertypub uses social means to build interop rather than ridged specifications, kinda inspiring. Be human on the openweb
