The Datastore would have fairly few attributes:
UniqueID (as usual)
Name (human-readable name, maybe indicating the technology, e.g. StorageTek)
Type (disk, tape, ... - open enumeration)
Capacity (NB this is in the schema as a separate object for technical reasons but is really just an attribute)
would this be 1-to-1 between DataStore and Capacity? - Sergio
The relation to StorageEnvironment and/or StorageShare remains open for discussion as there are other issues there (e.g. whether we want the Environment at all), but conceptually you would want a relation between the Share and whichever DataStore(s) store the data for that Share. That can be one to many, e.g. if Custodial/Online uses disk+tape, as in WLCG.
