Data Architecture document updated
by Allen Luniewski 30 Mar '07

30 Mar '07

New version stored on GridForge: http://forge.ogf.org/sf/docman/do/viewDocument/projects.ogsa-d-wg/docman.ro… This update addresses a number of trackers: Artifact artf5828 : Create a "VO" Section Artifact artf5827 : VO Role in Security Added new section to chapter 2 on VOs. Reviewed Security and Storage sections - no changes made. Artifact artf5831 : Turn section 11.5 (Federation: Updates to Policy)... Moved text from the Federation policy section to the Policy section in chapter 2. Updated the Federation policy section in the context of what was moved to chapter 2. Artifact artf5829 : Check Interaction of 8.7 (Storage & Transfer) and Transfer 8.7 still seems valid to me. I added a paragraph to tie it back to Transfer. Artifact artf5820 : 2.2: Data Access vs. Data Transfer Added a few sentences to try and add to the clarification that was already there. I thought that this section was pretty well written frankly. Artifact artf5821 : 2.2: Definition of "dataset" Tweaked definition of dataset in 2.2 and the glossary in the light of the Dublin Core definition by changing "syntax" to "defined syntax".
