[Building Sakai] Content "read" permission and Assignment uploads

[Jim Mezzanotte]

I'm trying to figure out how content access is handled for student
uploads in Assignments.

>From testing (2.9 and Sakai 10), I've confirmed that a student user
cannot upload a submission attachment in Assignments if the site's
resources "content.read" permission is not enabled for that role.
Instead of uploading, the system displays "operation could not be
completed at this time."

Submission attachments are stored in the Admin Workspace resources.
The "read" permission controls access to a site's Resources--without
this permission, users don't see the tool. But I'm assuming the
permission is also tied to access for the Admin WS resources, and that
the "content.new" (upload) permission is being handled automatically
(since each attachment file gets its own folder).

There might be use cases where content "read" access is not required
in a site where assignments are being submitted (for example you might
use Drop Box instead). So ideally, there should be no dependency
between the "read" permission and upload ability in Assignments. But
I'm not sure if this dependency is necessary, given the structure for
storage of attachment files.

Thanks in advance to whoever can shed some light on this!
