All items submitted to ATLAS include the date of submission, date of creation and the last updated date. This is by default a live view of the current state of the work. However, faculty may also view snapshots of all work submitted at any that point in time following submission. Anyone viewing the workspace can switch between snapshots in time and live views to see how work has progressed. The snapshots are a copy of the work at a point in time, which means the student can continue to develop the work without affecting the view the tutor has of the work.
