Investigation: specifying unique IDs

[timhodson]

Investigate: Can we not rely on Moodle to assign IDs for use by resource_link_id.

There are two tables which track resource_link_ids depending on which path is used to create the LTI link.

• mdl_lti used when using core LTI.
• mdl_aspirelists defined and used by our plugin

In certain scenarios where courses are restored into a fresh moodle the resource_link_id cannot be guarunteed to be the same. If we could mint our own, and store it we could have it imported into the new moodle database without loss or change.

Moodle is using an auto incremented value for the aspirelists table. The order in which courses are restored will affect the ID that is given to the restored LTI entries.
