Hi,
I’m one of the developers of https://lauti.org, an Open Source Community Calendar. We are currently investigating on how best to integrate LAUTI into the fediverse. Our friends from https://bonfirenetworks.org/ suggested we should implement the C2S Protocol instead of the S2S Protocol. This would allow a single group or place to connect to an existing ap actor and publish the event there (we would propably also allow for the instance admin to publish all events to a single actor). Our benefit would be, that the implementation would be way easier and for users it’s nice, that they have to follow only one actor instead of multiple ones. As we understand it this would be the opposite direction as other federated event software like https://mobilizon.org/ is doing it.
We would love some feedback on this from people better understanding activitypub and the fediverse.
