No objections were raised to the minutes.  

The agenda was augmented with "GGF preparation", "OGSA WG report" and "LSG Research Group".


2) Action report
 
- Dave to reconfigure tracker mail [Done, in that no mail is sent when an artefact is created.  We need the GridForge maintainers to correctly configure the tracker to allow messages to the list.]

- Dave to reply to Torsten of the TM-RG, inviting him to our session [Done.  We are also invited to the TM-RG session.]

4) Data Scenarios

Stephen talked us through his draft document.  We discussed some details of the template and the replication use case.

In particular we suggested that the "consumer" in the diagram might be a data service that abstracts the underlying mechanism.  This would raise questions about data transfer.

Stephen to update replication use case to match the interfaces described in the architecture document.  ALso delete the sections on performance and security, replacing them with a sentence in the summary to mention those issues if appropriate.


5) Security requirements for data grids

The Life Sciences Grid Research Group mailed the security area asking them to collaborate on security issues that affect life sciences Grids.  This has obvious overlaps with our activity on security requirements.

Dave to invite the LSG RG to our community meeting at GGF.  We should establish a dialog with them to capture and extend our requirements.

For next week's agenda:  attending the LSG workshop at GGF.


6) Wrap up 

DONM  - Next week. GGF preparations; data transfer.
