• Enable Sabre\CalDAV\Schedule\Plugin. This is pretty easy.
• Make sure that the CalDAV backend also implements Sabre\CalDAV\Backend\SchedulingSupport.

Currently there seems to be more activity in the calendar-rework (branch). I hope this will lead to a working new calendar app soon, as this is in the work for a long time already. Anyway, maybe it is a good idea to take a little bit more time to focus on implementing a unified Web/Cal/CardDAV endpoint in core and use this in the calendar rework here, see owncloud/core#5939. As far as I know this is a (fartime) goal in core already, with first steps to be found in the private repository of @DeepDiver1975: https://github.com/DeepDiver1975/dav. As it looks like CalDAV still has to be implemented here, this might be the chance to do it right at the first place, instead of doing the same work twice and changing the underlying CalDAV implementation later on.

Any opinions on how the calendar-rework should be handled? @georgehrke @jancborchardt @raghunayyar @DeepDiver1975 @karlitschek

AFAIK there is no ETA for the dav app yet. The current plan is to release rework with 9.0. If the dav app is ready by then and enough time is left, we should definitely remove our own caldav implementation and make use of the dav app. Until then, we need our own one, to be sure, that we can provide a well-tested caldav implementation when releasing rework with ownCloud 9.

@DeepDiver1975 I'm afraid I missed your lightning talk at conf. Is the dav app only supposed to provide a unified interface for web-/card-/caldav or will it also take care of actually managing the calendars and it's corresponding events/journals/todos?

@georgehrke There seems to be an ETA now which says OC9: owncloud/core#20371 As this app will hopefully make it into OC9 too, is it planned to use the CalDAV endpoint in core?
@DeepDiver1975 ?

With 9.0 core will ship webdav, carddav and caldav.
we will have a contacts app purely running on CardDAV - would be great to have the same for CalDAV.

@georgehrke scheduling support is part of 9.0 in core - please have a look at owncloud/core#20371 - THX

scheduling support is part of 9.0 in core

Great! will test asap.
Will we use traditional owncloud like sharing or are we going to rely on caldav sharing?

[georgehrke]

The dav lib found by @Henni looks really straight forward, so that's definitely the way to go!
Though we should check how difficult it will be to implement subscriptions and sharing.

Moving to the dav lib should actually not be too hard, because we already parse the ical in javascript, so it's almost just a matter of replacing the api.

[georgehrke]

caldav will be provided by the dav app.
Will create a dedicated ticket for implementing a caldav client in javascript.
