Hi Michael, Thanks for the email. The Data Use Case Scenarios document is just an early draft at this stage and so is not yet on the OGSA Data WG site (I don't think). But we are hoping to add more scenarios to it over the next few weeks and months. However, since the document might well be a "work in progress" for quite a while, it would probably be a good idea if a version is put on GridForge fairly shortly. I intend to do a bit more work on it over the next couple of weeks, so will try to put a version on GridForge at the beginning of September. Cheers, Stephen. -----Original Message----- From: Michael Behrens [mailto:behrens@r2ad.com] Sent: 10 August 2005 01:39 To: Stephen Davey Cc: ogsa-d-wg@ggf.org; acs-wg@ggf.org Subject: Re: [ogsa-d-wg] [acs-wg] Data Use Case Scenarios document Albiet a bit late, I just read the use-case document - looks good. With regard to replication, it seems that the ACS-WG might need to consider that portion so I'm also CC'ing this to the ACS team. I presume the use-case is available from the OGSA-D-WG site. Thanks!

Hi everyone, Attached is the beginnings of a list of Data Use Case Scenarios, which also includes the template sub-sections for each use case described.

I have basically taken the original OGSA use case template and merged the "Use Case Situation Analysis" section into the "Summary" section 2.1 and renamed section 2.4 slightly. I have also deleted sections 2.5 & 2.6 since security and performance considerations will be part of the Data Architecture document and would probably have just led to repetition. This then leaves the sections: 2.1 Summary 2.2 Scenarios 2.3 Involved Resources 2.4 Functional Design 2.5 References

Hopefully these sections will be all that is needed for the Data (infrastructure) Use Cases that we have. Any comments can be discussed on Wednesday 15th June.

Cheers, Stephen.
