OGSA Data Scenarios document v0.5
by Stephen Davey 08 Nov '05

08 Nov '05

Hi everyone, Attached is my latest version of the OGSA Data Scenarios document v0.5. I have added several more possible scenarios to the initial list (on page 2), although I imagine that they may not all end up listed in the final version of the doc. I have made some small changes to the Data Integration scenario by adding a version in which the data discovery and schema mapping are done largely manually, and a version in which the data integration service (magically!!!) does it for you. I have also added a first pass at a Data Staging scenario - still work in progress this one. Cheers, Stephen. ---------------------------------------------------------------------- Stephen Davey, NextGrid Software Architect, National e-Science Centre, 15 South College St., Edinburgh, EH8 9AA, UK Tel: +44 131 6 509820
