Osada will be spun off (separated from Zap) and officially abandoned. If you want to take over the project, go for it. The implementation of Zot6 there is now frozen because future Zot6 work (and Zot8 – more on that in a moment) will not be compatible with ActivityPub. At all. As far as I know Osada is the only viable ActivityPub server for events and groups, but Friendica and Hubzilla aren’t very far off.Mike Macgirvin, lead developer
For those of you who don’t remember, Osada was a new platform with a UI reminiscent of Hubzilla that was specifically developed to support both Zot6 and ActivityPub-based networks. Macgirvin seems to indicate, in hindsight, that this was a mistake.
Zot6 uses Activitystreams (not ActivityPub) as a serialisation format. The actor/object model may be elegant for expressing content, but it falls on its face when relayed between two actors with different permission expectations. ActivityPub folks haven’t encountered this issue because they have no working permissions system.
