Not aware of any widely used AP implementations that use locations, events, etc. but I think Nextcloud@mastodon.xyz is heading in that direction.
Also I think objects can be (or contain) multiple types so an event could also be a note which Mastodon could munch on making for interesting ideas to spread announcements? My AP knowledge is limited though.
@cwebber is a busy person but a good person to bounce ideas off...
@mhall119@cwebber@msh@ted I'd like to participate as well but Telegram is a bit of a non-starter (requires an app to get started). Is there a log of conversations somewhere that can be followed (or an IRC bridge?).
@mhall119@msh@cwebber@ted That's quite alright. I already moved out of my comfort zone in running the app to log in. Asking for a photo confirmed that Telegram wasn't going to be a pleasant experience for me.
