JSCalendar:
- https://datatracker.ietf.org/doc/draft-ietf-calext-jscalendar/
- https://datatracker.ietf.org/doc/draft-ietf-calext-jscalendar-icalendar/
- Last call finished May 25th
- Didn’t get feedback on the mailing list
- Feedback at CalConnect
    - timeZone on isAllDay events
    - datetime string not include time component for all day events (it’s already not fixed size)
- DISCUSSION
    - An alternative is to add an `isAllDay` flag to events that have a `DATETIME` range as a way to indicate to clients that they should be presented as all day events.
    - This matches what Microsoft do.
    - We will take this to the list.
Scheduling Controls:
- https://datatracker.ietf.org/doc/draft-ietf-calext-caldav-scheduling-controls/
- how do we advertise server support?
- Bron to write up -01
Eventpub:
- https://datatracker.ietf.org/doc/draft-ietf-calext-eventpub-extensions/
- Discussion about the SOURCE property (drop it)
- Need to define “social calendaring”.
Vpoll:
- https://datatracker.ietf.org/doc/draft-calext-vpoll/
- Having re-read it, looks like it needs some restructuring.
Subscription upgrade
- Mike is working on a reformatted version
Scheduling for JSCalendar:
- iMIP add another part?
    - { { text/plain, text/html, text/calendar, application/jscalendar+json }, application/ics }
- Scheduling Upgrade: per-event URI rather than per-calendar URI allowing CalDAV / REST / JMAP access to individual events with individual URI
Future Work:
- ischedule redux
- calendar sharing informational drafts
- valarm extensions
- caldav sync / proxy


Push:
- Marten
- There’s a draft already → split into two documents
    - The push protocol
    - Specific DAV implementation of the model
- Hoping to finish first document quite soon - translating into metanorma.
- Probably also should go to dispatch - at least generic part is not calendar specific.


NEXT STEPS:
- Sharing and Push to DISPATCH
    - Probably only 5 people.
    - Might be good to have a chat with AD (Barry) first.
    - Bron to have a chat with Barry.
- Call for adoption
    - valarm extensions
- Plan for another interim at next CalConnect in October.
