The topic the Chadwick currently is working on is federal organisation management in OpenStack to allow users from a wide number of IDPs to all take on the same roles and to get access to the same set of resources.
On top of that, David Chadwick has a PhD student who is looking into all sorts of management in OpenStack, and - in fact - in federated Cloud, because the team is interested in two questions. From the administrative perspective the question is: which virtual organisation role do I need to give to this user in order for him to be able to access these services? From the user's perspective the question is: I have got this particular virtual organisation role, what can I do with it?
The team is performing the work through the creation of policy administration points which the user can read in the policies from the various Clouds, or he can analyze the policies or store them in a relational database and then try to answer these questions about what roles you need to actually access resources and what resources you can access with a particular role.
