I'm just uploading another new version, in which I've rewritten the section on (meta)data catalogs / registries in the new approved style. I'll stop working on this document now.

I've made an attempt at rewriting the Cache section. I've put a table of operations at the start, clarified that there are potentially many cache services (one per set of interfaces), expanded the description of the create operation, added a list of properties, and added sub-headings to improve the structure. I've borrowed a lot from the replication section. Mario, if you let me know when you have a suitable version, I'll copy these changes into it. I can also update some of the glossary entries. At some point I need to work on the Catalog section. I'll try to do this soon. Other thoughts: In my view, section 2 should give an overview of the components of our toolkit, the capabilities they provide, some high-level patterns for their use, and some cross-cutting concerns. For example, it should state that we describe storage management, explain the interaction of access and transfer, state that replication can be used to control these, and that composite services can be created using federation and caching. It should explain how these services may be hidden behind client libraries (e.g. for legacy support). Finally, it should describe how policy issues are handled across the various components. Section 3.7 should be discussing the support for policies provided by OGSA, e.g. WS-Policy, WS-Agreement, etc. It's not our job to define general mechanisms such as these. Currently this section does talk about data-specific issues as well. I wonder whether we should say something in section 2 about service creation. Throughout our document we have tended to assume the existence of factory services, each with an appropriate createXXX operation. I think this is a useful way to structure our document; the createXXX operations let us describe the issues that need to be taken into account when creating a particular service (such as policies, location, etc.). But in the larger OGSA context, might services be created as part of the provisioning capabilities of the architecture rather than a specific factory service? Section 10.3 still discusses a DestroyReplica operation. I think we agreed to remove this (it's not in the table at the start of section 10).

OGSA Data: Teleconference, Friday, 8 June
by Allen Luniewski 05 Jun '07

05 Jun '07

We will have our next teleconference this Friday, 8 June, at the usual time. The call-in #s for this call are as follows: US: 877-421-0030. or 770-615-1247 UK: 0808-234-1969, or 207-026-0533 Passcode: 357276 NOTE that this are different numbers than in past meetings! Agenda for this meeting: 1. Early discussion: Roll call Note taker Minutes approval 2. Action Report: [Allen] Review the policy subsection in the light of the discussion. [Dave] Make sure that the architecture document explains that we can handle sets of files. [Allen] Check the relation between RNS and storage-specific directory management. [Dave] mail Simon to clarify the "classify" operation on metadata catalogues. [Chris] send out second draft of GFS scenario. [Dave] to create or reuse scenario slides for main OGSA slide set. * To be added to the trackers [Mike] Section 12 - Metadata Catalogue and Replication - needs to be worked on [Mario] Describe the semantics of destruction of services/data in the early section. The service has to define it's semantics. [Mario] Include a paragraph in the Appendix setting the context and scope of each of the specs. [Mario] Use the data access patterns to motivate the data access section. [Mario] In the data access section, the create operation needs to be scoped down. Maybe break it down into separate operations. [?] The glossary needs to be updated. [?] The cache section needs to be completed. [?] Appendix 1 listing specs ? already done? [?] Appendix 2 summary of general interfaces ? to be completed in final draft? [?] Appendix 3 mappings to specs ? to be completed in final draft? [Dave] to revise the EMS/Data scenarios [?] Add Data Caching scenario [?] Add Data Warehousing scenario [Dave] Add Metadata Catalogue scenario [?] Incorporate Avaki and Oracle scenarios as motivation. [Dave] What about asynchronous operations and aborting requests? (Suspend/Resume/Abort Request) 3. Discussion: minimum set of tasks to complete the Architecture document. 4.
