Reagan Moore has given us a list of all the SRB access commands. These will be a useful check as to whether our architecture provides all the necessary functionality. (Although I expect these commands to map to various different parts of our architecture, not just our data access section).

Mario: I added to the document the set of data access commands (74 in total) used by the Storage Resource Broker data grid to manage distributed shared collections. These commands go beyond simple data access, and include commands needed to minimize network latencies, manage distributed data, and federate independent data grids. The desire is to broaden the goals of the proposed data access mechanisms to make them relevant to a large number of established international data grids. A standard interface that is not able to support the operations provided by existing data grids will artificially restrict itself. Note that the functionality of the commands that are listed is required to support a diverse set of applications ranging from data grids to digital libraries to preservation environments.

Hi, Please find enclosed an updated (but not yet finished) version of a

Data Access setion that is being prepared as a contribution to the OGSA Data Archtecture document. The document is still a bit rough so my apologies for that. I would like people who might want to help write this section (and contribute to the OGSA Data document in general). In particular:

- I need someone to put some proper content in the ByteIO section. - Folks to review and put forward their requirements/comments. - DAIS folks to read the DAIS part and make sure it makes sense.

This is a work in progress. Thanks in advance for any input you may have or any bits that you may wish to contribute.

Mario
