FW: Data Provenance Scenario
by Stephen Davey 07 Jun '06

07 Jun '06

The current Provenance scenario is included in the attached doc - still work in progress though. Cheers, Stephen. -------------------------- Stephen Davey, National e-Science Centre, Edinburgh, UK. -----Original Message----- From: Luc Moreau [mailto:L.Moreau@ecs.soton.ac.uk] Sent: 25 May 2006 12:35 To: Stephen Davey Subject: Re: Data Provenance Scenario Stephen, I reads nicely. I added a section to introduce the notion of provenance store, which can be implemented by 1 or more provenance services. I also suggested a scenario for the multiple store configuration. Is this suitable? It may have to be reformatted according to the style of the rest of the document. Do you have enough material to complete the example of interfaces? Currently, there is no discussion of security? Do you want me to write a paragraph of the security issues we're facing in the second scenario?

First rough draft of GFS scenario
by Christopher Jordan 07 Jun '06

07 Jun '06

My apologies for the last-minute delivery - for reasons I can't fully explain, I ended up having to rewrite the whole thing pretty much from scratch yesterday. And I actually think I was happier with it the first time I wrote it. Also, I realized after writing the scenarios section that I put most of the stuff that should really be in the functional design section in the scenario section, so I'll need to reorganize the material significantly, but I hope this is enough to generate some constructive criticism. Thanks. ---------------------------------------------------- Chris Jordan HPC Systems Engineer High End Computing Systems Group San Diego Supercomputer Center ctjordan(a)sdsc.edu 858.534.8347
