  1. SPG Report Summary, Findings, and Recommendations R. Ullman ES-DSWG 13 November 2012 Annapolis, Maryland

  2. SPG History • SPG Charter established in 2004 • Need seen for independent, stakeholder community inputs into standards being used for the development and evolution of the NASA EO Data systems • Initial focus was on developing a Charter, a Standards Process, and an Instruction to Authors • First RFC submitted for SPG review was the DAP 2.0 – from James Gallagher and the OpenDAP Group • The Standards Process revised to shorten the process for international standards, for tech notes that are near standards, ….. SPG / ES-DSWG / 13 November 2012 / Annapolis

  3. SPG Process Changes • Level 1 requirement to use SPG standards is a game changer both for projects and for SPG • SMAP, Ice Bridge, CLAREO sought advice • Revived interest in standards (GeoTIFF, MENDS, etc) • ESDIS will use general SPG documentation and process flow (RFC, review, recommendation). • SPG “Standing Process Group” is replaced by ESDIS direct action. • TWG’s to be individually chartered by ESDIS as necessary • May perform functions other than coordination of RFC review – studies, documentation, develop recommendations, etc. SPG / ES-DSWG / 13 November 2012 / Annapolis

  4. SPG Standards • Reviewed and endorsed a wide array of community standards and technical notes including: • OGC WMS 1.3 & 1.1.1 • HDF5 & HDF EOS5 • AURA Guidelines • NetCDFClassic & NETCDF4 • GCMD DIF • ECHO Metadata • ICARTT SPG / ES-DSWG / 13 November 2012 / Annapolis

  5. SPG Findings • Level 1 requirements to use endorsed standards leverages NASA Earth science mission formulation activity • Innovation in HDF5/ netCDF, ISO • May facilitate distributed development and evolution of EO data systems, and reduction of mission stovepipes. • Mandated participation by ROSES awardees leverages NASA Earth data innovation and can build community buy-in • DAP, ICARTT, AQUA standards • Voluntary community participation is difficult to sustain • GeoTIFF, ISO metadata, Science content standards SPG / ES-DSWG / 13 November 2012 / Annapolis

  6. SPG Go-forward Recommendations • Standards Development Process (SDP) recommendations for success: • An ESDIS sponsored SDP must be managed with funded participants. • Otherwise, result is the same as current SPG – reactive, outcome and schedule uncertain. • Output of the SDP must be documented with an RFC and provided for community review (i.e. Standards Process) • Otherwise result is same as before SPG, newDIS – directive, subject to disconnect with community needs. SPG / ES-DSWG / 13 November 2012 / Annapolis

  7. Work in Progress • Continuing website communication improvements • Standards Process Review (Charter) • GeoTIFF • KML • Datacasting • Mobile Computing for NASA Earth Science  • Conventions for HDF5   • Conventions for ISO 19115 Metadata • Preservation Information Architecture • OpenSearch SPG / ES-DSWG / 13 November 2012 / Annapolis
