I have uploaded the latest version of the architecture document to GridForge for GGF-15.  It can be found at:

        https://forge.gridforum.org/projects/ogsa-d-wg/document/Strawman-Architecture_V.5.1/en/1

I will retain the write lock for now on the document.  If you need to make updates, either send them to me or ask me for the lock and I will give you the write lock.

Thanks.
