I've uploaded a new version of the architecture document - https://forge.gridforum.org/sf/docman/do/downloadDocument/projects.ogsa- d-wg/docman.root.working_drafts/doc13621/2. Changes: - I've moved some generic description out of the data access section into the introductory sections. - I've tidied the data access section. At least, I think it's tidier; please could the authors take a look and tell me what I've messed up? - I've made the discussion of policies and agreements more consistent throughout the document. This includes moving a list of example policies from the federation section into section 2. - I've tidied the glossary, removing unused items and ensuring that certain other terms are used consistently in the text. Note: where I've copied chunks of text from one place to another, I switched off change tracking because such large deletions and additions don't tell you much. Instead, I've highlighted the text in yellow where it now appears. Still to do (at least): - Add a discussion of interfaces to the data caching section. - Ditto for the replication section. - Revise the metadata catalog section. - Tidy the appendix list of standards. I'm about to go on holiday for a week, so these tasks won't get done for a while.
