And for me personally the coolest is that it integrates quite seamlessly with my Nextcloud as it also supports Webdav for files and CalDav for calendars. It also uses a standard LAMP server, so setup is very similar to Nextcloud.
I recommend you have a look at it and maybe someone could think of a way to link these two PHP apps even better?
HubZilla has a really advanced SSO solution build in (see: https://macgirvin.com/wiki/mike/OpenWebAuth/Home ) so if Nextcloud had support for that, it would probably allow interesting direct interaction with various HubZilla instances.
There is also build in ActivityPub support (to allow federation with Mastodon etc.)… so indeed federated file sharing might work.
Edit: Got an reply from the HubZilla creator:
You should be able to interact just fine with their most recent releases if you install the ‘pubcrawl’ addon (the Hubzilla ActivityPub plugin).
Try it and let us know. Bonus points for writing a detailed bug report if you encounter difficulty.
Our applications use completely different and incompatible mechanisms for access control so sharing files with privacy controls may have problems. Public files should work fine.
I’m not sure. I know that Hubzilla supports both ActivityPub and WebDAV. You are welcome to join testing it here. Just register a free account and hop on Matrix/Hubzilla as detailed on the post and website.
Correct, it was very simple to share the photo. Happy to say it displayed perfectly in Hubzilla. Huge amounts of potential there!
Hubzilla sees many other federated protocols and supports XMPP chat… so would it be possible to federate with Nextcloud Talk over XMPP? I haven’t used that app yet. I’m happy to file a feature request, etc.
Nextcloud Talk doesn’t support XMPP yet
Neither does Hubzilla really… it is not geared towards real-time chat. But there is plugin for Hubzilla based on ConverseJS that gives you a nice XMPP chat on your Hubzilla instance.
I was originally under the impression that this was just a type of ActivityPub which is supported by HubZilla, but apparently this isn’t quite true. I started a thread over at their developers forum ( https://project.hubzilla.org/channel/hubzilla ) though to see if they are interested to implement OCM on top of their existing federated and webdav capable file sharing system.
No it does not. You can easily install Hubzilla on a sub-domain. If you are taking about sub-directories… yes that might not work. But that is a huge hassle to configure properly and a potential security risk anyway. If you are still putting your websites in sub-directories instead of subdomains you should change your approach
