ownCloud

Enable users to directly upload files from their private ownCloud/Nextcloud storage into Moodle.

Prerequisites	Moodle 3.3.2 ownCloud 10.0.1 (or newer) OAuth 2 App from Marketplace HTTPS-secured connection	Moodle 3.3.2 Nextcloud 14.0.4 (or newer) HTTPS-secured connection

Features:
The repository is available anywhere where users deal with uploading files. Users can choose whether they want to UPLOAD a file or LINK to it:

• UPLOAD works as usual, i.e. it uploads a copy, except that you don't need to download it first! Avoid the hassle of having to download files onto your computer first before you can re-upload them into Moodle – particularly useful on mobile devices, but also sweet on the desktop!
  
• LINK let's you select a particular file, but doesn't create a copy. That means that, if you change the file in ownCloud/Nextcloud later, it will magically change in Moodle, too. In the background this feature automatically creates a public link in ownCloud/Nextcloud and uses that link in Moodle – no further manual interaction required.
• ACCESS CONTROLLED LINKS means that the files reside at ownCloud/Nextcloud instead of being copied to Moodle. Nevertheless, you can be sure that, once uploaded, a file cannot be changed by students, i.e., even if they were the owner, their write permissions are revoked. Files are owned by a special ownCloud/Nextcloud account for Moodle that is responsible for granting correct access rights.

Your institution has multiple ownCloud and/or Nextcloud instances? As an administrator you can add as many instances as you require!

This plugin does not store any user's private passwords in order to authenticate against ownCloud/Nextcloud. Instead, it leverages the passwordless workflow of OAuth 2!

File linking: Nextcloud once had a technical limitation that prohibited creating shares automatically. The issue has been fixed in early 2018 and is part of Nextcloud 13.0.1.

Access controlled links: Prior to Nextcloud 14.0.1, whenever you authorised Moodle to access your Nextcloud, you logged out at the browser at the same time. This made using access controlled links a little tedious: To access an access controlled link file you first have to authorise Moodle, then re-login in to Nextcloud in the browser. This issue has been resolved in Nextcloud 14.0.1.

Additional issues were resolved in Nextcloud 14.0.4.
