Hi list,
I'm starting to learn Fedora Commons and have a couple of questions about
the access control mechanism.
Suppose in my repository I have a conceptual hierarchy for objects. At the
top level is projects, under which are experiments, under which are
measurement values, under which are different kinds of digital objects
(Excel/Word/pdf/text files, etc.). The above types of objects have a
"contains" relationship. Moreover, a lower-level object may belong to
multiple higher level objects, e.g., an experiment may belong to multiple
projects. Access control to the objects are based on the project
ownership/membership. Roughly speaking, a project owner has all access
rights to the objects within the project. a project member has read access
to all objects within the project. Project owner may choose to grant/rescind
project membership.
I understand that objects can have object-level security policies. Let's
assume for the moment that Tomcat is the servlet container and is used for
managing security. Here are my questions:
1. Can the above access rights-related operations be done through a web
interface?
2. What is the best practice for doing that?
I'd appreciate it very much if someone could sketch an outline or point me
to some further reading. I've gone through the online documentation and it
doesn't seem to have the specific information I'm after, though I may be
wrong.
Thanks in advance!
Best regards
Yuan-Fang
