RE: [ogsa-d-wg] [acs-wg] Data Use Case Scenarios document
by Stephen Davey 15 Aug '05

15 Aug '05

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(a)ggf.org; acs-wg(a)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!

Data Use Case Scenarios document
by Stephen Davey 10 Aug '05

10 Aug '05

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. ------------------------------------------------------------------- Stephen Davey, NextGrid Software Architect, National e-Science Centre, 15 South College St., Edinburgh, EH8 9AA, UK Tel: +44 131 6 509820

FW: ogsa data scenarios v0.3
by Dave Berry 26 Jul '05

26 Jul '05

All, Here is Stephen's revision of the OGSA Data Scenarios document. I would like to allocate some time in a future telcon to discuss this and how it fits with the architecture document. (E.g. the names of services and interfaces in the two documents should be chosen to agree with each other). Some of tomorrow's discussion on data transfer may affect the replication scenario, as that requires data transfer functionality. Best wishes, Dave. _____ From: Stephen Davey Sent: 26 July 2005 15:03 To: Dave Berry Subject: ogsa data scenarios v0.3 Hi Dave, Attached is my latest data architecture scenarios doc with the final additions to the data replication use case. In the intro section I have also tried to divide up the data scenarios into simplified architectural patterns which hopefully capture the characteristics of the different use cases. Please forward it to everyone if you are happy with it. Cheers, Stephen. ------------------------------------------------------------------------ ----- Stephen Davey, NextGrid Software Architect, National e-Science Centre, 15 South College St., Edinburgh, EH8 9AA, UK Tel: +44 131 6 509820
