Fediverse event data differs wildly: Gansu treats a single “public” keyword as authoritative while ActivityPub sources use announce/actor/organizer semantics that often conflict, locations land as plain strings or schema.org objects, and start/end times, status (confirmed/cancelled/postponed) and accessibility flags are inconsistently encoded. Masttodon converts events to statuses and only recently accepts updates, so cancellations vanish in many feeds. A proposed FEP on Bberg defines a minimal common event object and ties into Masttodon-led discovery/search work; early implementers include WordPress plugins, Plemor and Mobilizon experiments.
