Hi Andy,
Yes. GraphOracleSem and DatasetGraphOracleSem allow addition/deletion of
triples and quads, respectively.
Users can choose to commit or rollback transactions at any time. Without
committing, one session can of course
see its own changes. But other sessions won't.
We will use http://jena.apache.org in our document, if we haven't already done
so :)
Cheers,
Zhe

Hi Andy,
FYI, Oracle has recently moved to Apache Jena 2.7.2 to align with Top
Quadrant's tools and

Thanks,

Zhe,
Thanks for the information. It's beginning to look like transaction boundaries
are a significant factor, for example, deleting and adding triples as a signal
ACID action. How's that handled? Via
oracle.spatial.rdf.client.jena.GraphOracleSem?

PS Hopefully the docuemnt will change http://jena.sourceforge.net/ to
http://jena.apache.org/ as well :-) Your lawyers can advise on the legal side.

The Jena project works in public. The history of the discussions for
BulkUpdateHandler and SDB are in various public archives.
I would like to see acknowledgement of prior discussions and the
intentions behind the changes.
We made the graph-level bulk update handler change at 2.10.0 and we've
had 2.10.1 since then.
There was a message on the users list Nov 2012

Oracle are aware of the changes:
http://mail-archives.apache.org/mod_mbox/jena-users/201211.mbox/%3C50B688D8.9040600%40oracle.com%3E
Oracle do not track Jena versions.
Oracle (at least 11g) is for Jena 2.6.2 (2009-10-16)

I do know that the complexities arising in Jena lead to costs for
storage implementers. I want to reduce those costs in the long term.
