[ogsa-d-wg] [acs-wg] Data Use Case Scenarios document

[pete at ziu.net]

Hi Keisuke and Mike,

I read the current architecture draft ogsa-d-wg has up on their site, and
there appears to be no conflicts.  They do mention non-master replication
in the context of "peer-to-peer". I refered to these a little differently
in terms of "push", "pull", and "bi-directional".  Mike, did you find the
use cases up on ogsa-d or just through communications with Steven?  I am
working to continue to add detail to the replication presentation.  I am
attempting to define a "ReplicaElement" structure which will have
properties of a unique instance id, replica id, the actual value of the
data, modification and author history, and security constraint data.  This
one structure should be able to be used to represent a piece of data, a
collection, a graph (tree), and a database, for a collection of replicas.
Hopefully I can get this out before ogsa face2face to help stimulate the
replication topics.

Hi Mike

# I removed ogsa-d-wg from recipients since non-subscriber post will
# be rejected:-)


Thanks for a heads up! So they include a data replication use case
in their scope. Did you find any conflicts in their doc, especially
between their requirements and our current specification?
