Many of these projects are for people organising events, with features like attendee signup.
Is anyone working on projects for discovering events that other people organise and then directing people back to the original home of the event online?
(I know that may seem like a subtle distinction, but I think that brings up some important points on how the app works - and I back this up with 7 years running a popular events listing site with user feedback on this.)
I am, and even thought it’s very early days for my project I wanted to introduce it: https://www.theoccasionoctopus.net/
This is an event discovery app where everyone can have their own account and list things that interest them. You can then follow other people and discover other interesting events they list. There is no RSVP features; instead we try to direct people back to the original home of this event, wherever that is.
It’s intended not to only rely on people adding events by hand, but to encourage other people to publish event open data it can reuse. It can import from iCal, and it has a full write API and some existing bots that scrape information from other websites (with backlinks).
There is basic federation, but, er, not with ActivityPub yet - that’s something I want to support in the future. Expect more questions like this one.
Anyway, it’s early days and there are many rough edges, but I’m just going to keep working on it slowly. I’m interested to chat with others working on event discovery, and interested in anything to encourage more open data on events!
