SIENA requested a brief statement on adoption use cases and the design of the OCCI specification set for their roadmapping effort. As this is applicable to the current NIST cloud standards roadmap document development, I have written one and attach it here as a submission also to the NIST document. Please feel free to offer any feedback or requests for changes for incorporation into the above efforts. Thanks, Alan Alan Sill, Ph.D Senior Scientist, High Performance Computing Center Adjunct Professor of Physics, TTU Vice President of Standards, Open Grid Forum ==================================================================== : Alan Sill, Texas Tech University Office: Drane 162, MS 4-1167 : : e-mail: Alan.Sill@ttu.edu ph. 806-742-4350 fax 806-742-4358 : ====================================================================
