Re: Logical relations between TLT and courses

Ok, that's better.

Is it latest available TLT version, or latest published TLT version? IIRC, we can only subscribe to published TLT version.
Depends on what kind of listing we are making :)
For teachers, to create a class on existing course - latest published.
For admins, listing courses they have access to - latest available.

       Here is another take for course relations to outside world.
       Course is connected to UMO base. That raises few problems:

       1) When we are talking about the courses, such as available
       courses - what version of the TLT is used to show the course
       information? The course title, languages, etc - it's all
       stored in TLT (that is a UMO).
       2) When a class is connected to the course, we need to grant,
       for instance, STUDY permission to the TLT. Again, we need to
       to know a particular version of TLT to work with.

       My current understanding is - we use latest published version
       of the TLT. If I'm correct, then it would be nice to have a
       field in UMO base, *ub_latest_published_version*, pointing to
       the latest published version of the UMO. Implementation
       includes simple modifications in umo_publish() and umo_delete().

   When we are doing course listings, we use info from latest TLT
