Role Based Restrictions

At the moment I can restrict view and edit of pages based on users and groups. I would prefere a role based model.

This model would alow to define roles on the space similar to project roles in JIRA. You could then add user and groups to the roles (again just like in JIRA).
Giving the roles meaningfull names would allow for more crear restrictions like:

• Restrict view to "technical writer", "developer" and "customer"
• Restrict edit to "technical writer"

It would make setting restrictions more easy for normal user as they could use are meaning full role name to restrict there pages instead of figuring out witch group would be the right choice. (You could also use good names for groups to support this.)

This would also make changes in the restrictions more easy, as you could change youst witch user and groups have witch role instead of changeing alle ristrictions in the space.
