2. We learned a lot! Whether or not we have produced anything of value to the rest of the group, we each have a much better understanding for ourselves of how the components of the DOE2000 program fit together and how they have many common needs.

3. Recurring Theme in Discussions To collaborate (or interoperate) we need information. Our biggest barrier is the difficulty of finding all the relevant information we need in order to use a tool or to work together ourselves.

4. Integration, Integration, Integration Integration is going to require that we make metadata generated by the various tools generally available in a common manner outside of / between tools.

5. Use Cases zValidate large data sets using information on software tools and signed test datasets in libraries zAlert users of a dataset of a new “limitation” based on new discoveries about software used in processing it zGraphically link several tools to create/analyze/visualize/record data zRoute data for signatures, validation, and automatically route from notebook to library

6. Similar needs exist for component software development zWhat are capabilities of a component in terms of platform, expected error, scaling, memory, performance characteristics zWhat are effects of code modifications on above capabilities zThis is much more than just a version control system

7. Information Workflow (metadata categories) zData Workflow w CCA, CPSEs zSoftware Workflow wSoftware development wData Validation zRecords/Legal Workflow wNotebooks wDigital Libraries zCollaboration Workflow wsession setup wbusiness workflow zScientific Workflow wprocessing history wCPSEs

8. Metadata Middleware zMetadata definition wattributes wrelationships (e.g. collections) wnotifications zMetadata extraction zMetadata translation zMetadata discovery (e.g. agents) zMetadata Engine/Repository zMetadata driven tools w(new tools, integration of existing tools) z(Graphical) Workflow definition tools

9. Recommended actions zFormalize development of metadata middleware in a new group/metagroup zMetadata definition projects for data, software, records, … zVerify that groups are working together

10. Support zNot everything should be deployed and supported, but zResearch ->Prototype zReview Prototype zIf yes, fund pilot deployment zReview pilot zIf yes, fund deployment/support zAssumed - feedback to researchers at each stage of development

11. Other needs we identified, some current, some new zCommon Component Architecture zAutomatic differentiation tools wtools for computing derivatives, sensitivity, … zVisualization framework wneed data descriptors zAlgorithm development zPreconditioning interfaces zEquation solver interface

12. Collaboration Issues from Point of View of a Potential User zCollaborative visualization zKeeping track of data sets wlater annotations to data sets as people use them for research zUnencumbered software zVideoconferencing deployment should be integrated into tools zTool deployment zIndexing/directory service to locate metadata/data zpersistence of data -> how to handle?

13. Important topics for impact on user community zFacilitate deployment winstall, support, licensing, platforms winterfaces to other tools zSecurity wenable access wlegal aspects (notebooks) wneed something stable and supportable wsingle security context

14. The tools needed for DOE2000 are useful for SSI but need to be enhanced to provide: zdevelopment / hardening zdeployment / support zhigher performance versions wprocessing speed wlarge scale data sets MICS SSI/CSET Research Hardened Tools Q: What can support SSI? A: Lots of things!

15. DOE 2000 can supply to SSI: Tools for zbuilding more sophisticated applications wcomponents, not monolithic zdata management, information handling wabstractions wsecurity infrastructure wwhere does data live zVisualization framework

16. Interaction with other agencies zSee last two slides from Group M-2! zQuote from Group A-1: w“Interagency cooperation works best from the bottom up rather than the top down.”
