Long-term Data Management
It is understandable that group PIs want to have continued ownership of work produced in their lab as researchers and team members come and go over time, and want to continue to have access to, and control over, work produced in the past once the people who created it have gone.
In RSpace, LabGroup members displayed in the group management page for your LabGroup are the current members of that group. When someone leaves the Lab (and therefore the LabGroup), they can be removed from the group list by clicking the Remove button next to their entry. However, their work continues to be stored on the system, and remains accessible to the LabGroup PI.
