Subject: RE: regrep Security

yep. good idea. We do not want to immerse ourselves into a sea of roles and
as you pointed out make it simple.

I would like to push for extensibility so that one can extend the model - I
have some specific scenarios for complex schemes (of, course ;-)) but that
should not be the norm.

I think access control should work out relatively smoothly - after Tokyo -
provided that our granularity doesn't get too fine.  We have a notion of
ownership with respect to who should have control over what registry
objects.  In my mind we get:

   The Registration Authority (RA) is the superowner and has system
   The Submitting Organization (SO) owns everything they submitted
   The SO can Modify anything they submitted provided it doesn't adversely
affect an object submitted by someone else - this can be controlled by how
we define the effect of Registry Services.
   The General Public can't modify anything.
   Other RA's may not be able to modify anything but they may be able to
see things that SO's and the General Public are not generally able to see,
e.g. administrative information.

We have at least the following roles to consider:

   General Public - e.g. Web Browsers
   RA's from other RegRep installations
   RO's (Responsible organizations) Named as such by SO's when submitting

I'd be very cautious about defining too many other roles, since it could
get very complex very quickly.
