[mailto:glue-wg-bounces@ogf.org] On Behalf Of Maarten Litmaath said: Can we collapse the tape with the cache into a single Datastore that has both an Online and a Nearline component?
I would say not, the basic idea of a Datastore is to make it homogeneous. Is there a real problem with having a many-to-many relation between Share and Datastore? In LDAP I think it's OK, you just put pointers in the objects as appropriate, i.e. a Share has ForeignKeys pointing to all of its related Datastores (and you could have pointers the other way as well, Datastore to Share, but I'm not sure it's necessary). Does that give a significant problem in the other technologies? For relational implementations you'd need an intermediate table but it's not that bad (we have that for all multivalued attributes anyway). For XML I don't know how it works. Stephen
