Server: Federated calendar and contacts sharing [$210.00]

[georgehrke]

There already is a federated file sharing, that allows you to share files among different Nextcloud instances.
We need something similar for calendars and address books.

There is an open bounty on this issue. Add to the bounty at Bountysource

[mimi89999]

Any workaround to get that?

[georgehrke]

well, you can use public calendar sharing and webcal feeds for read-only "federated" shares, but that's only Nextcloud11+ and will only work in the web interface

[georgehrke]

@schiessle Let's tackle this at the next hackweek, deal?

[schiessle]

@georgehrke deal! 😃

[MorrisJobke]

Seem to not have happened :/

[georgehrke]

@MorrisJobke we discussed it, but it was too complex for one week.

@schiessle Do you mind posting the notes we took? :)

[MorrisJobke]

Looks like it is included in #9345 ;) cc @schiessle

[schiessle]

yes, I wrote you a mail with some details @georgehrke
As this can be implemented now without any changes to the server, we could work on this together after the Nextcloud 14 release

[MorrisJobke]

@schiessle What is the status of this? Doesn't seem to get into 14 anymore, right? move to 15?

[rugk]

Any news here?

[dev4223]

Hi there, would love to have this feature. Any status news? Thanks a lot.

[wargreen]

Hi, same here.
Thanks for who achieve it functionality !

[georgehrke]

Please use the Github Reactions feature instead of commenting +1, 👍 etc. These kinds of comments just unnecessarily notify everyone subscribed to this issue. Thx! :)

[rugk]

@georgehrke That's true. However, after half a year of inactivity in an issue, it is very appropriate to ask whether there are any news, i.e. whether someone worked on it, or the issue has been forgotten.

Especially, as this was planned for Nextcloud 14 and right now v15 has already been released already.

Sadly it's not an exception. What the people at Nextcloud Groupware are doing is non-transparent. It's not the only issue where they refuse to answer.
It's sad, because they've done and they are still doing tremendous work.

There is nothing hidden here. As you can see in the right sidebar it's not assigned to any milestone.
For each version there is a feature planning, usually at the community hackweek. If we decide to implement this in the upcoming version, it will be assigned to the respecting milestone.

(And yes, obviously i could assign this to the 16 milestone, but i can already guarantee you that i won't have enough time to implement it and that people will complain if we assign it to a milestone and postpone it. 😉)

You good Sir have my wallet!

[rugk]

Wow $150.00 USD for this now. Nice.

Would possibly be good if Nextcloud could add BugBounty integration here, so the money is displayed in the title etc.

There should be one in place already ...

Well… it is not displayed :thinking:

I'm wondering if the federated calendar features envisioned for NextCloud will only federate between NC instances, or whether there will be interop with other events calendar sites running software that implements ActivityPub? Friendica events federate over AP already, there is at least one instance of Gath.io that federates events over AP, and Mobilizon has a beta test site up now (will eventually federate over AP). It would be great to have interop between all these services and any others that support AP (GetTogether, Gancio etc), and there's been an ongoing discussion about how to achieve this here:

Is it possible to implement sharing/federation with a group on another nextcloud?

[chaptergy]

Officially federating calendars is implemented via the Circles App using federated circles, however in practice it has never worked for me. I'm trying it periodically, however it has not been fixed yet. (See issue https://github.com/nextcloud/circles/issues/254)

[genofire]

My fault found the group settings in the global settings of the nextcloud:

• Allow users on this server to receive group shares from other servers
• Allow users on this server to send shares to groups on other servers

[daraelmin]

Maybe this pull request will solve this issue: #9345

It should allow the implementation of federated calendar and contact sharing.

[georgehrke]

Not really. What will actually bring this forward is https://github.com/nextcloud/server/pull/20214

[daraelmin]

Ok but in the description of the pull request it is said "allow the implementation of federated calendar and contact sharing."

I don't want to see Bounty source take the money I've put on this issue for the nextcloud dev.
Read this thread for more info (https://help.nextcloud.com/t/dont-use-bountysource-anymore/84943/55)

If there's no solution to federate calendar, I'd really prefer that my money goes to someone whos working on the project I want to support.

[georgehrke]

9345 moved this forward a lot, by allowing other apps to reuse the existing federation logic.

However, we still need #20214, to actually allow writing calendar / contacts without a user account, just by knowing a token.

[daraelmin]

I might be wrong, but wouldn't it be easier to add a caldav and carddav client function (module?) on the server side of nextcloud?

Especially since reading #20096, I'm wondering if, in the end, federated sharing isn't just going to be too limiting for the end user. Indeed, this type of design will not allow you to synchronize calendars hosted on other dns without administrator intervention (the externe calendar must be listed in trusted cloud and must accept federation).

Going through the federation plugin may not be the right solution, at least for my needs.

Is there a way or an existing module to connect via caldav er carddav from the server to another?

[georgehrke]

That is the plan. Public calendar endpoints are nothing else but CalDAV endpoints for that matter.
