1. ICEO Standards Working GroupSteven F. Browdy, Co-Chair ADC WorkshopWashington, D.C.September, 2007 ADC Meeting 2007-09-12

2. Summary of ISWG Achievements • GEOSS Standards and Interoperability Registry made public. • Contributed by IEEE (http://seabass.ieee-earth.org/group/geoss) • Initial round of enhancements completed. • Demo planned for November at GEO Summit. • Earth Observation Portal Study almost complete. • 175 portals identified, over 100 portals reviewed. • First draft complete (final report to be submitted to AIP Web Portal Group). • EO Standards Survey publicly available. • Gathered some standards information for the standards register. • Found new ways to attract responders, but still have low response rate. • http://www.dbscale.com/ISWGSurvey/ ADC Meeting 2007-09-12

3. Summary of ISWG Achievements • Standards Development Organization (SDO) Table • It is an accessible record of organizations responsible for standards relevant to GEOSS. • Consolidation and cleanup has taken place. • Link between SDO table and Standards Survey to be established. • Standards Taxonomy prepared for feedback • Sent to MMI (Marine Metadata Initiative) for hosting and feedback. • Being updated for more detail. • Updated no more than once per quarter. ADC Meeting 2007-09-12

4. Standards Taxonomy(Current State) • 17 categories identified. • Broadly designed. • Can be found for review at: • http://www.grss-ieee.org/files/ISWG_Standards_Taxonomy.pdf • http://marinemetadata.org/examples/external/iswgstandards • Each category is defined and given examples. ADC Meeting 2007-09-12

5. Standards Taxonomy(Current State) • The current categories are: • Metadata; Data Format; Catalog/Registry Service; • Data Access; Streaming Protocols; Semantics; • Portrayal and Display Service; • Data Transformation Services; QA/QC; Schema; • Modeling, Simulation, or Analytic Processing Service; • Archival; Communications & Telecommunications; • Data Acquisition; Engineering Process; • Development Environments & Software Languages; • Technical Documentation. • To provide feedback, go to the Taxonomy Forum at http://seabass.ieee.org/groups/geoss ADC Meeting 2007-09-12

6. Standards Taxonomy(Example Page) ADC Meeting 2007-09-12

7. Standards Taxonomy(Near-Term Goals) • Add dimension ??? • Break out broad categories into parent-child relationships • Not necessarily required for each category • e.g. data format  graphics, numerical data, etc. • e.g. metadata  sensor, service, etc. • Add more categories based upon SME feedback. • Feature it on the standards registry. • Make it accessible via XML. • Store it in a database table for easy access by registries. • Modify and reissue Standards Survey based on new taxonomy. ADC Meeting 2007-09-12

8. Standards Registry (Current State) • Backend register populated with > 80 records. • Input of proposed additions requires self-registration and manual data entry. • Entries to be reviewed by SIF? • Current entry form is not optimal. ADC Meeting 2007-09-12

9. Standards Registry (Current State) ADC Meeting 2007-09-12

10. Standards Registry (Near-Term Goals) • Interoperability Goals • To have this registry work seamlessly with the services registry. • To have this registry participate in a workflow situation to support operation of the SIF. • Usability Goals • To make the UI to the register more user friendly. • To facilitate better searching. ADC Meeting 2007-09-12

11. Standards Registry (Interoperability Goals) • Methods to get special arrangements for registered component services (if opted for registration)? • Web service to accept special arrangements from the service registry… • Web service to request special arrangements from the service registry… • Or do it manually until the two registries are synchronized. Thereafter, proper functionality will maintain synchronization. • Service registry needs to interoperate, as designed, with the standards registry. • Currently Z39.50 protocol is functional, SOAP to be implemented. • Need to update pick lists at the service registry dynamically. • Need to implement link from the service registry to the standards registry to pre-fill standards entry form, when necessary. • Need to validate, at the service registry, that the special arrangement has been entered successfully at the standards registry. ADC Meeting 2007-09-12

12. Standards Registry (Usability Goals) • Implement FAQ, general help, context-sensitive help, and required field notification. • Make some content changes for clarity. • Add fields for URL / URN of the service that the standard or special arrangement is associated with, when applicable. • Add user authentication levels. • Needed to support SIF operation. • Needed to control access to editing capabilities of register entries. • Implement workflow to support SIF goals. • Used with the SIF ops procedures for processing and evaluating submitted standards and special arrangements. ADC Meeting 2007-09-12

13. Standards Registry Test-Bed? • “The Architecture and Data Committee will provide guidelines for test procedures for test and verification.” • Quoted from 10-year IP Ref Doc in Tactical Guidance draft document. • Is a testing infrastructure to validate and accept interoperability arrangements too close to “certification?” • Does GEOSS go down this road? Recent SIF discussions shy away from this. • A testing infrastructure can support the SIF, but its applicability is questionable, due to the scope of requirements and resources. • GEOSS-controlled vs. private industry??? • External testing authority??? • Some requirements: • Automated testing (primarily). • Regression testing for modifications. • Policy linking results to SIF decisions. • … and a whole host of other requirements. • A completely non-trivial task  ADC Meeting 2007-09-12

14. Summary of ISWG Near-Term Goals • Achieve interoperability between registries. • Enhance Standards Registry. • Revise taxonomy and update Standards Survey. • Complete EO Portal study and deliver final report. • Finish revising SDO table. To Be Achieved ASAP ADC Meeting 2007-09-12
