The only backpack implementing OBv1.0 was Mozilla Backpack. It closed
in 2019 and their badges were moved to https://backpack.openbadges.org/
by Badgr.
However, as Badgr is supporting OBv2.0 too, it makes no sense keep OBv1.0
implementation in Moodle: it has caused some issues and over-complicates
current code.
The logic to create the issuer has been moved to the backpack form
in order to improve the workflow and update the apiBase with the
proper value comming from the badgeconnect.json manifest file.
So, as part of this change in the workflow, the following changes
has been also implemented (to make the UI easier for users):
- The "Open Badges" oAuth issuer button has been removed from the
"OAuth Services" admin page. As they are created/updated when a backpack
is saved, this button is not required anymore.
- The "OAuth2 services" and "Backpack API URL" parameters have been
removed from the Manage backpacks form, because they are created on
the fly each time the backpack is saved.
Backpack URLs (web and API) can have up to 255. However, the form
for creating/editing them, doesn't allow URLs with more than 50
characters. This patch align limitation to DB value (255).
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.
