Provide return link for integration

[lkiesow]

Similar to Studio, it would be nice if a system integrating the Editor could provide a return link to the editor via URL parameter which would then be shown to users when they are finished editing and when they would currently be stuck in a dead end (e.g. after starting the processing):

Which systems are allowed should be a configuration option in the editor configuration file so that you cannot generate an editor link which at the end will lead you to a malicious site. But this can be a very simple list of URL prefixes like ["https://opencast.org/", "https://university.edu/"].

I am not really sure whether the callback url should be an option in the config file. I think this should not be a problem, since URL parameters have a higher priority and the option in the file could be seen as a default value.

On the other hand, the list of allowed domains/prefixes should be configurable only in the file. Otherwise, this mechanism would not provide any protection.

I think Back to LMS is too specific as we don't know if the return link refers to a LMS. I would suggest to name it more generic, e.g. Back to previous system.

This is also an important feature for our institution, as users sometimes need to edit several videos in a row and want to go back to where they started. Or they may simply want to pick up where they left off before they started the editor.

I agree with that. It would be even better to make the button name configurable. You could specify a name in the config file for each permitted URL or prefix. This name then would be displayed as button text:

"Tobira": "https://tobira.opencast.org" --> Button text = "Back to Tobira"
"ILIAS": "https://ilias.university.edu" --> "Back to ILIAS"

The „Back to LMS“ in my example is really just an example. It's not only too specific, but we also should avoid using cryptic abbreviations like LMS. I would suggest that users who pass on a return URL should also pass on a system name to go back to.

Meaning the label is “Back to {{ system }}” with system = 'previous system as a sane default, but users cann pass on the system name and you end with “Back to Moodle”, “back to Stud.IP”, “Back to Tobira”, …

I wouldn't put the whole label in the configuration. That makes internationalization annoying.

@Arnei, I think this can be closed since #1100 was merged.
