Ways of representing our event object schema - lessons from open standards (there are many!)

[evolve2k]

As we consider ways to implement #ActivityPub into our FOSS Community Calendar Ecosystem platform Koalagator, I've been looking over the differing specs for how to specify the event object schema.

Have any other folk wrestled with this?Asking before I get arms deep in this stuff.

For those playing at home...

W3C Activity Vocabulary - Event

This specification describes the Activity vocabulary. It is intended to be used in the context of the ActivityStreams 2.0 format and provides a foundational vocabulary for activity structures, and specific activity types.

Fediverse Enhancement Proposal
FEP-8a8e: A common approach to using the Event object type

ActivityStreams defines the Object Type Event. In real-world applications, the event object immediately showed the need for extension. Applications featuring Event objects have often chosen to add additional attributes and clarifications (i.e., interpretations) in order to implement their particular use case. This proposal clarifies and extends the ActivityPub standard to address the needs that have arisen in real-world implementations.

iCalendar Standard (RFC 5545)

iCalendar was first defined as a standard as RFC 2445 in 1998 by the Internet Engineering Task Force (IETF). Today, iCalendar is used to import and synchronize events on various platforms, including smart phones, computer and web applications.

FYI I just responded to your mastodon post: https://social.coop/@smallcircles/114606294483551845

I think both #Gancio and #Mobilizon are projects to check out.

There is also recent discussion on the #ActivityPub #SocialHub forum around events #interoperability:
