I could not identify the license (or origin) of some external libraries you added to the admin UI. The license to these need to be clarified or they need to be removed.
The problematic files I found:
Based on the Bower and NPM informations, it seems that the library is also available under the MIT license.
After some research, it seems that the library named angular-sortable is not the really "angular-sortable" (#1) from this address but "ui-sortable" (#2). The good news is that the second one is licensed under MIT.
That is great news!
I will add the it to the NOTICE file as required.
Just to avoid further confusion, I will ask the author if he would be willing to add a proper license header.
If he does, let us update the file in the long run
Notes are updated in https://bitbucket.org/opencast-community/matterhorn/pull-request/515
I have also asked the author to add a proper header:
That means, this is resolved, yay!
Missed that the pull request for the other libs that will be removed is still open.
