Hi everyone, Attached is my latest scenarios document - version 0.7 which includes Allen's comments on v0.6. It also has a Storage scenario from Peter and I have made a start at a Personal Data Service scenario, and a bit of a Data Discovery scenario. A copy is also on GridForge - https://forge.gridforum.org/docman2/ViewCategory.php?group_id=150&catego ry_id=1033 . I wonder if we should try to ensure that there is a least one scenario that is focussed on each of the main sections in the Data Architecture document? The architecture sections and related scenarios are currently as follows: Data Description - ??? Data Transfer - data transfer scenario, data staging scenario. Data Access - personal data service scenario?? Storage Resource Management - storage scenario. Cache Services - ??? Data Replication - data replication scenario. Data Federation - data integration scenario, personal data service scenario. Metadata Catalogue & Registries - data discovery scenario? Personal Data Service - personal data service scenario. Transformational Services - ??? Data Streams - ??? Also mentioned in the Data Architecture document are: Naming - personal data service scenario?? Metadata - data discovery scenario?? Security Transactions Sessions Execution Management Services (EMS) Hope people get time to read it before the telcon tomorrow, cheers, Stephen. ---------------------------------------------------------------------- Stephen Davey, NextGrid Software Architect, National e-Science Centre, 15 South College St., Edinburgh, EH8 9AA, UK Tel: +44 131 6 509820
