Hi, I still have reservations about the resource, service, site etc entities. The share expresses the relationship between resource and service. I don't think we need "element" any more.
From the point of view of service discovery we need to find a service which has a share with a policy expressing that a particular VO has some resources. Is all VO specific policy in the share?
If we get rid of element both services and resources might need a relationship to a site - in which case we should try to define precisely what that relationship means. It may be different for a resource and a service Should I presume that a Computing service is a service (inheritance). If this is the case we need to think at some stage just how this will be realised. Steve
