Re: What next for SDO Java? - Externalise Store

[Susan Paice <SU...@uk.ibm.com>]

Please externalise the concept of a Store backed DataObject so that it is 
possible to write a lazy-parsing Data Access Service without resorting to 
accessing impl classes.

The DynamicStoreDataObjectImpl & StoreDataObjectImpl classes looks as if 
they may well provide the functional ability, but there doesn't appear to 
be anyway to get them primed with an EStore other than by calling the impl 
classes directly. 

Thanks,
Sue.

Re: What next for SDO Java? - Externalise Store

Hi Sue,
   providing a solution to lazy instantiation of data graphs is a subject
that's on the SDO spec group's agenda.  Currently the SDO spec JIRA that's
tracking this issue proposes a "DataObjectResolver" which looks not too
dissimilar to the current Store stuff that's in SDO1/EMF, and resolving this
is slated for the SDO 3 spec.  To that extent it's a bit hard to know how to
approach this.  If there's interest in the community we could bring the
current implementation up to scratch, with no guarantees that when the spec
group closes the issue off that there wouldn't be work to do for a DAS
implementer to come into line with the spec.  I'd like to hear from anyone
else whether they have an inteest in this concept,  since the more noise
from the community the higher priority this becomes.

Best Regards, Kelvin.
