WebCal calendars cannot be seen (selected) by DAVDROID on mobile system about calendar HOT 25 CLOSED

Webcal calendars are subscriptions that don't seem to be supported by DAVdroid. Use ICSdroid instead : https://davdroid.bitfire.at/faq/entry/subscribe-ics-file/

Webcal calendars are subscriptions that don't seem to be supported by DAVdroid.

These calendars should be reported as read-only CalDAV calendars by Nextclound, and then be detected by DAVdroid.

Do you know whether Nextcloud reports these subscriptions as calendars?

No, it does not. It's not a calendar collection, but a subscription.

from calendar.

These calendars are also not cached on the server, only in the users browser.

No, it does not. It's not a calendar collection, but a subscription.

Ah ok, so CalDAV clients can't see it of course.

from calendar.

They do, this calendar app is also only a caldav client.
The iOS and OS X calendar app will also display it properly.

As fas as I know the CalDAV RFC, CalDAV clients can see only calendar collections. Have I missed something?

from calendar.

The subscribed collection is not an official part of the CalDAV standard. It's some extension by apple

from calendar.

I see, Nextcloud reports:

<d:response>
    <d:href>/nextcloud/remote.php/dav/calendars/test/my-subscription/</d:href>
    <d:propstat>
        <d:prop>
        <d:resourcetype>
            <d:collection/>
            <cs:subscribed/>
        </d:resourcetype>
[…]

So it's not a calendar collection and thus can't be listed (and synchronized) by DAVdroid.

Thanks for your help.

from calendar.

Is there any reason why only Apple's non-standard extension is used? Couldn't the resource be described like this:

<d:resourcetype>
    <d:collection/>
    <cs:subscribed/>
    <cs:calendar/>
</d:resourcetype>

from calendar.

Because there is no official standard for it and Apples private standard is the most widely used one

from calendar.

What is wrong with describing it as calendar?

from calendar.

The calendar will be empty. The entries are not stored on the server, but the browser loads them directly.

from calendar.

Also contact birthdays are exposed as calendar but WebCAL subscriptions aren't. Both are described as subscriptions in the Calendar UI.

It wasn't clear to me that the calendar UI is not a pure CalDAV client.

from calendar.

Subscriptions are just read-only calendars. if you share a calendar with someone read-only it will also show up as subscription.

from calendar.

I'm arguing that it is counter-intuitive to label two things as subscription when they have entirely different semantics in CalDAV.

from calendar.

Well, but the semantic here is calendars = read-write, subscriptions = readonly. I'm very open for a discussion to rename subscription to something else.

when they have entirely different semantics in CalDAV.

Sorry, but ordinary users frankly don't give a shit about what CalDAV is and how it handles calendars.

from calendar.

Sorry, but ordinary users frankly don't give a shit about CalDAV.

Users do give a shit as soon as they use that protocol to sync ownCloud with DAVDroid or any other non-Apple client. They have to give even more of a shit as soon as they notice that only parts of their subscriptions are discovered by standards-conformant CalDAV clients.

We are considering making them available as ordinary caldav calendars, but this requires changes to the server-part. It's nothing we can do in a simple calendar release. Something like this would come in a bigger Nextcloud release.

from calendar.

That's totally understandable.

from calendar.

@georgehrke @untitaker so for making them available as ordinary CalDAV calendars, should there maybe be a separate planning issue opened? :)

from calendar.

Any news on this? I would like my subscribed calendar feeds to show up on my mobile device.

from calendar.

For starters, see nextcloud/server#1497

from calendar.

Are there any news about this? Vdirsyncer still can not sync Nextcloud's WebCal subscriptions, and the workaround on the client side is janky at best.

from calendar.

@leopoldfajtak please open a new issue with details, as things have changed since then
