The OBv2.0 specification includes a field "Criteria" for
BadgeClass. Until now, this field was filled using the
URL of the badge assertion, but that is causing some issues
in Badgr because it linked to the badge assertion of the
first user sending this badge to the Badgr backpack (so then,
the following users linked to the first user assertion page
too).
This patch adds a new page, badgeclass.php which will be
used from now to display any badge information which is
not related to any assertion (like happens with the criteria
in BadgeClass).
High-resolution image for a badge (f3) should be sent to external
backpacks through JSON and WS methods.
Besides, when a badge is cloned, the high-resolution image should be
used to avoid the copied looks blurry.
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.
