Noticing the very good improvement Martin did in the CVS for the Resource Module (thanks also to Gustav for the idea), I tried a test to restore course created in 1.4 dev, (where two instances type of resource are no more available) into previous version of Moodle:
- created a course with some resources (uploaded file and web link) in Moodle 1.4 dev, latest CVS
- made a backup
- downloaded the backup from 1.4 dev and uploaded to 1.3.3 stable
- re-created the course from scratch
The course is correctly restored, but the two types of resource no more available in 1.3 won't work Althought I'm aware that backward compatibility cannot be guaranteed, I just wonder if a workaround may exist: I'm thinking to the release of Moodle 1.4, and the possibility of a course restore from a 1.4 'stable' to a Moodle installation that for any reason wish to stick to 1.3.x.
