Working on a NIP proposal for conference session events (for use in nostr:npub1c0nfstrlj0jy8kvl953v84hudwnpgad0zx709z0ey7nmjp0llegslzg243 ) and I realized this design could potentially be generalized further for any kind of calendar event with some intersection with what nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z suggested. A conference could just be a calendar (list of sessions modeled as calendar events) with some extra bits of metadata on top. I’ll try to put out a pull request soon. nostr:note125c69p7p8fj0jsfyqejpksd8e7edpludjl7yer2lywauq9gvfunslq6ftt
