Replication - Draft available.  Good enough for the moment?
Federation - unchanged.  Good enough for the moment?

Allen to paste material together into the document this week so that people can have a look at it before the F2F.

- ByteIO (2 hours)

- Short presentations about each section, identifying questions for relating to other sections.  (1 hour)

- Data transfer (1 hour)

- Data access (1 hour)

- How to identify data and how to get the bits into and out of storage (1 hour)

- Overview section (1 hour)

- Cross-cutting themes (1 hour)

- Wrap-up and futures (30 minutes)

Dave to mail round this draft.

Allen asked how to address security, policy management, naming?  Dave suggested that he presents them to the OGSA WG at Tuesday's F2F.  Allen clarified his question: each part of the data architecture may have particular concerns.
E.g. Replication: do security tokens get replicated?
     Storage: security for backup?
     Access: in some environments a query may be forbidden depending on earlier queries (e.g. finding too much aggregate information).


6) Wrap up

Dave to forward final meeting info.
Allen requested people to put F2F presentations on web site.
Minutes would also be desirable.

DONM:   F2F Next week.  Telcon week after.
