I think that for example the search feature has nothing to do with activity pub but it’s a feature of each of those software that are using activity pub (Lemmy, mastodon etc). I would guess it operates on those internal structures each of those implementations are using.

yea my bad, it looks open source :D

Then maybe I got confused sorry. Somebody mentioned it and then the post was saying it’s a service I thought it wasn’t open. Will check it properly later. Shouldn’t have spoke so quickly I guess

However it does not look like it is open source.

Isn’t that a (implementation) detail beyond the point of uselessness though? The big point for me is there. To keep it with the metaphor, that tree is also quite a complex structure, yet still useless.

Could this be of any help ? https://www.firsttimersonly.com/

Personally I was wondering the same too, so I thought to focus on libraries/projects that I already like or find the codebase exciting in some way. Haven’t done any major contribution though, with the little time I have available. So… i dont know if that is good advice or not, just something that makes sense to me.

However let me just bring into mind that we recently defederated from some Lemmy instances and for which reasons we did that (as beehaw I mean).

Friendica, I believe, federates their groups. You can see them from mastodon as a user. I guess in AP vocabulary they are an actor. You can post to the group from mastodon too.
