[ Apologies for multiple copies ] The Resource Usage Service working group has been developing a service interface for the recording (and retrieval) of information pertaining to the use of resources on the Grid. Information is passed back and forth using the Usage Record XML schema developed by this group. An implementation has also been created and tested at the University of Manchester. The service is likely to be deployed on the UK National Grid Service, and may also become part of future releases of the OMII software. At past meetings, the turn out has been fairly poor. We are keen to finish this work in some way, and want to push things forward at GGF13. The revised specification will be presented, and the recent implementation work discussed. Accountancy-related work is clearly not as glamourous as some activities, but it is a fundamental part of the Grid. I am writing to encourage you to turn up to our meeting in Seoul. The meeting is on Tuesday, March 15 from 3pm-4:30pm in the Sapphire Ballroom 1. It would be really great if some members of the UR-WG could attend - after all, this is closely related work. The up-to-date specification, currently based on WS-I, can be found in the RUS-WG mailing list archives at: http://www-unix.gridforum.org/mail_archive/rus-wg/2005/02/msg00001.html Thanks for your time, Jon MacLaren.
