FW: enclosed replica management architecture doc

Arie sent us this reference following the discussion last week. Dave. -----Original Message----- From: Arie Shoshani [mailto:shoshani@lbl.gov] Sent: 30 March 2006 03:13 To: shoshani(a)lbl.gov Cc: Dave Berry; Ann Chervenak; pkunszt(a)cscs.ch; Allen Luniewski; Kurt Stockinger; David Smith; Malcolm Atkinson; martinde(a)us.ibm.com; Patrick Dantressangle; Simon Laws; Yin Chen; Srm-Devel (E-mail) Subject: enclosed replica management architecture doc Dave, Enclosed is the pointer to a paper I mentioned during the conference call today that was published recently which describes a Replica Registration Service (RRS). I want to draw your attention to section 4 that briefly describes how this service fits as one of three services that can be used by a Replica Management Service (RMS). I think this fits your concept of "composable services". *RRS: Replica Registration Service for Data Grids*, /Arie Shoshani, Alex Sim, Kurt Stockinger, /Proceedings of VLDB Workshop on Data Management in Grids (VLDB-Grids'05), September 2005. http://sdm.lbl.gov/~arie/papers/RRS.VLDB-Grid.2005.pdf Also, I want to mention some desired functionality when using storage services as parts of other services (I mentioned that briefly during the call). These include: 1) there needs to be a way to requesting to reserve storage space, and passing that information to the transfer service. 2) there needs to be a way of passing to the storage service the desire to keep files in the storage space for some lifetime, and releasing the lifetime commitment when done. This does not necessarily imply removing the files. Arie

Estimated date for public comment?
by Dave Berry 26 Mar '06

26 Mar '06

All, The OGSA-D WG has missed its rather optimistic schedule for getting the Version 1 documents into public comment. Allen & I propose changing this date to August, with publication 4 months later. If I don't hear any objections by Wednesday, I will update the "living charter" document on GridForge. Best wishes, Dave Berry Deputy Director, Research & E-infrastructure Development National e-Science Centre, 15 South College Street Edinburgh, EH8 9AA Tel: +44 131 651 4039
