Hi,
We are dealing with a similar issue where we want to be able to author
rights at the collection level. To do this we have created a
redirected POLICY datastream in the child object to point to a
datastream in the Parent object which contains the XACML. So the
collection object would look like:
Collection Object
-----------------------
DC datastream
RDF datastream
CHILD_POLICY datastream
Child
-------
DC datastream
RDF datastream
POLICY datastream (of type External pointing to parent CHILD_POLICY
datastream).
We are using fedora 2.2.3.
Thanks

Hello,
I have been trying to determine the best way to set XACML security
policies for objects which belong to a particular collection, as
defined in their RELS-EXT datastreams. Unless I am missing
something, there doesn't seem to be a way to directly determine the
collection an object belongs to via XACML. The best idea I have
come up with is to assign a special Content Model to all objects
that I want to be access-restricted, and target this specific
content model in an XACML policy that denies access to non-
authenticated users.
Has anyone dealt with a similar issue? Any insight would be
appreciated.
I should mention we are currently using Fedora 2.2.1, but will
likely upgrade to 3.0 in the future (And if there is a better
solution in 3.0, I can try to make the "future" happen very quickly!)
Thanks for the help,
