Instead of running the site backpack validation every time badges/backpacks.php
page is loaded, an action button has been added to the backpacks with OB set
to 2.0 to let admins running manually this verification when needed.
When OBv2.0 support was added, the issuername and issuercontact
fields were changed to static.
In order to avoid confusion for the user, these fields shouldn't
be displayed for OBv2.0 or higher.
In MDL-67971, issuer_json.php was created, to display issuer JSON content.
However, some files were still using action=0 to display this information.
It has been replaced by issuer_json.php.
The action=0 support won't be removed (at least for now), because several
public badges URLs are using it.
Use the "expand" parameter so the backpack returns nested public
information about each badge in a public collection. This saves 2 requests per badge and
fixes the problem where we don't have permission to see some public badge details.
This commit combines several changes:
* Show authentication errors.
* Show more detailed authentication errors
* When the site backpack is different to the user backpack, show a warning
* Do not duplicate the apiversion and backpackurls in each user backpack.
* Do not support different issuer information for each badge with Open Badges v2.
* Add obversion to assertion url
* Combine separate badges upgrade steps and bump the version number.
* Don't show private collections.
* Push the larger image size to backpacks (512x512).
* BADGE_BACKPACKURL is deprecated
* Don't use property alignments, only alignment
Upgrade the support for Open Badges 2 to support a real open badges 2 backpack.
Moodle can only talk to one backpack at a time, so after switching backpacks, users
will have to manually disconnect and then reconnect their backpack to the new one.
This commit combines several changes:
* Split classes into badges namespace
* Publish expiry data with a badge
* Publish badge alignments in badges exported to the backpack.
* Export the criteria for a badge to the backpack.
Properly integration badges with competencies provided in Moodle.
Automatically grant the badge when the defined competencies are marked as proficient.
