On further investigation of the Storage Schema an unmet use case has
Use Case: Consider two VOs who use two different paths to access the
same StorageShare or alternatively one VO who can access the same
StorageShare via two different paths. Where there could be an asymmetry
with the ACLs for the SRM v2.2 space and the Path.
The latest schema would require a StorageShare to be instantiated for
each combination of path and SRM v2.2 space ACL, leading to n*m storage
shares duplicating a great deal of information.
The suggested solution is to split the StorageShare into the
StorageShare and StorageEnvironment where there is a one to many
relationship between the Environment and the Share. Both entities
inherit the ACLs from the AccessPolicy
At the same time this allows the AggregationID to be removed.
