Submissions Library

Project goal

Make activity module developers (not only Assignment developers) able to use submission types: both standard and community-developed.

Project scope

A library providing API for activity module submission types support implementation. Actual proposition is to make assignsubmission plugins system-level.

The existing modules requiring submissions (Assignment, Workshop) should use this library.

Relevant tracker issues

1. MDL-47344 - Allow usage of submission methods in other plugins

Use cases

1. Assignment: no comment.
2. Workshop: uses submissions but it's another code doing the same.
3. Lesson: as well as questions the submissions could be used at lessons for a small tasks. For example, a task at the end of lesson about MS Paint: draw an your dream house, save it and upload.
4. Community module: for example, Assignment with individual tasks could not re-implement all existing submission types.
5. Non-mod usage? Is there is no such cases this library should only work with activity modules.
