3. Task DA-09-01b Data, Metadata and Products Harmonization GEO ADC Meeting Sept. 15-16, 2009 Melbourne, Australia Ken McDonald NOAA/NESDIS kenneth.mcdonald@noaa.gov

4. Task Overview Task Description –Facilitate the development, availability and harmonization of data, metadata, and products commonly required across diverse societal benefit areas… Approach –Assess current capabilities Review and characterize contents of GEO registries Generate initial report –Analyze results Look at level of community adoption of various approaches Identify barriers to integration/interoperability/interuse Deliverable –Develop set of GEO recommendations Goal is convergence to harmonized set of standards Based on best practices and community directions

5. Task Team Formation GEO Call for Participation to GEO 2009-11 Work Plan –Eight responses received –Monthly telecons held since May –Participation off to slow start but improving CEOS team formed to coordinate space agency contributions to GEO task –Volunteers from Working Group on Information Systems and Services (WGISS) and Working Group on Calibration/Validation (WGCV) –Project kicked off at WGISS meeting in May –Effort broadened to include contributions to other GEO DA and AR tasks –Progress through regular telecons and email exchanges

7. Current Status Initial assessment of current GCI registries completed –Supported by Doug Nebert’s work with the GMU CSR team –Reviewed and discussed by both GEO and WGISS teams –GCI architecture is good but issues with contents Consistent and coherent discovery, search and access results Challenges of aggregation within components WGISS undertaking additional steps –Development of a domain model consistent with GCI ConOps –Relevant standards/guidelines and metadata requirements for discovery, search and access –Exploring clearinghouse requirements for remote sensing data products with distributed search capabilities

8. Next Steps Dedicated session at WGISS meeting in two weeks –Discussion of findings and future plans –Develop recommendations for GEO task(s) WGISS results/plans will be discussed at next GEO task telecon –Goal is to broaden recommendations and plans to address needs of non-satellite data and service providers Joint workshop being planned with GEO Task on Data Integration and Analysis Systems (DA-09-02a) in Washington on Nov. 11-12

9. Considerations Resources –Task activities will require a substantial effort from its contributors Team Balance –Assessments and recommendations have large potential impact –Team must have strong representation from all sectors of GEO community Relationship to Other GEO Activities –This task should complement and not compete with other tasks –It should leverage experience and results of the GCI Task Force and the SIF

10. From “Data Way Forward”, George Percivall Fusion is only possible with a harmonized information architecture GEOSS 10 Year Plan RD anticipates GEOSS will enable new value-added products resulting from fusion of diverse Earth Observation and socio- economic data. Harmonized information architecture allows sharing across different disciplines. DA-09-01b (data harmonization task) and AIP-3 can be a starting point for such information architecture. Multiple topics in an information architecture that must accommodate dataset lifecycle
