This meeting came about because of planned changes to the roles the 3g database introduces and will be propagated once the prometheus 3g database feed is introduced. It was widened into a general 3g feed/role management/new accounts discussion.

Prometheus 3g feed

The prometheus 3g database feed is ready to be switched on. Once running, it will work with the current 2g feed in the following way:

  • 2g and 3g infdb conduits will both run
  • any user seen by the 3g conduit will then be ignored by the 2g conduit

We hope to enable this feed by the end of August at the very latest. For this to happen, we need to make sure that (1) any implications of 3g roles changes are considered, and (2) there is enough disk space for new student accounts.

3g role changes

The rat-unit will produce a wiki page which summarises role changes which the 3g feed will introduce: actually as below -

  • All "class-*" roles will disappear for all students.
  • All "year-*" roles will disappear except for "year-ug[12345] and year-msc" which will be generated per-student as before.
  • While other changes are planned they will not be implemented before a formal review of roles and management has taken place.
  • All "old-degree-*" roles will disappear for all students pre-dating 2011 intake.
  • All other student related roles ("[[old|new]-]degree-*", "module-*") are retained as-is for now.
  • The 3g feed has no effect on staff and staff related roles - these remain sourced from 2g.

There was some discussion on how roles/entitlements should be managed, with an acceptance that there is perhaps no right way to do this. It is expected that, in the longer term, Devproj #197 will help.

In the short term, it will be up to the individual units to check/modify the roles/entitlements provision for the services which they provide. There is a risk that some things may fall through the cracks, so we may look at the best ways of detecting such issues.

Disk space

Switching on the 3g feed would mean the creation of approximately 350 new accounts (mostly new students). The services-unit will make the appropriate amount of disk space available and advise inf-unit accordingly.
