Pre Jan 10th meeting phone conference
Date: Monday, December 03, 2001 4 PM

Present: Shazhad, Chip, Torre, Doug, Andy, Mike, Ruth, Reagan

GDMP and PPDG: Shazhad: project is having a code review. Message passing system is being recoded to
include replies to each request. Scheduled for release
over the next 2 or 3 weeks. GDMP release 2.2. which will be in a month or
two. Planning to use a Host certificate instead of a gdmp service
certificate. Shazhad is working on this.  Start work on the GSUI user
interface - point and click. 
Andy: discussing open framework for introducing new protocols as part of the new
architecture. Protocols for catalogs explicitly. Would be open to
negotiation with Globus. PPDG work with WP2.  

Put PPDG contributions to WP2 on the agenda for January 10th.

Replication Requirements document:  Mike will check if there is the effort/expectation to update  this document  before Jan 10th.

End to End Error reporting/handling:  Noone is doing the errors in a systematic way. We can discuss whether it is possible to do this in a systematic way. Can't do this at this stage.

Reliable File transfer component in Globus: will be a complete standalone
file transfer layer below replication. Replication will be built on top of
this layer. Reliable queued requests  even without the catalog.  Would then
have another queuing mechanism above this. Regarded as PPDG work. Protyping
stage.  Queuing requests that are persistent across dissapearance of client
and/or server. Requirements and/or design document available for Jan 10th.
Effort in LBL on this too. Coordinate the work between them. No schedule to
date. Atlas would be happy to try this out. Would also apply as MOP
production would be able to transfer arbitrary data between sites.

Is this on the GDMP work plan - answer from PeterK. later in the week is "yes".

SRB: still providing additional capabilities beyond GridFTP. Another
possibility to have a parallel protocol to GridFTP to handle the extensions. 
Building GridFTP protocol on top of a SRB collection. Some later email exchange on 
this. WSDL interface on top of SRB. Standard SOAP protocol and WSDL
infrastructure. standard protocol of highest level - is this of interest to
the community. or at the bottom.  What capabilities need to be provided by a
Replication Service.

HRM interface document would be ready for posting on 25th Dec.  Proposal to
accept this as a PPDG white paper. Joint PPDG/SRM/EDG - Ruth will check.
