3) Planning for OGSA-WG F2F

Aims:
Get OGSA to review our documents
Review our docs
Highlight interactions between Data & rest of OGSA (e.g. make provisioning, scheduling, reservation generic; naming, generic properties)
Suggest some common scenarios
Highlight gaps (File description, session management, URIs for describing query languages, etc)

OGSA WG responds better to assertions rather than questions

- Dave to mail OGSA WG list to look at our docs for Monday.
- Dave to prepare some draft slides and send to list for review.


4) Review of architecture document

Dave outlined his recent changes, primarily moving generic material out of the data access section.

Alan noted that there is some confusion in the text about what is a policy and what is a property.  Both can be used to describe and configure the behaviour of services and resources.

Mario noted that the notes from a recent ByteIO telcon mentioned that factory operations are out of scope in OGSA.  We should check what was meant by this.
- Mario to talk to Neil about OGSA support for factory ops.

5) Wrap up
