  1. SPG Process & Endorsed RFCs Richard Ullman, Chair SPG October 21, 2009 ESDSWG Meeting Wilmington, Delaware

  2. Standards Role for Decadal Survey Data Systems Needs SPG Process Discussion - October 21, 2009 Selection and management will emphasize flexibility and accountability over centralization. More distributed geographically, functionally and managerially. Ability to add new data system components, independently developed and independently managed without unduly perturbing existing systems Responsiveness to defined communities: Innovation to serve new community needs encouraged. Diversity in implementation will be encouraged - with coordination at the interfaces

  3. Process Basics SPG Process Discussion - October 21, 2009 • 3 types of reviews and all reviews can be done simultaneously – some reviewers perform multiple reviews. • Technical specification review • Usefulness for purpose review • Operational readiness • If the proposed standard has been adopted by an another standards organization, then do not need a technical specification review • For a mature defacto standard, we will perform a subset of the three types of reviews. May not need an operational readiness review or usefulness for purpose review • The SPG will determine which reviews will be conducted for each proposed candidate standard. Can be a subset. • Encourage strong community leader – essential to the process

  4. TWG • Review Questions: • Technical Specification • Operational Readiness • Suitability for Use SPG • Initial Screening • Initial review of the RFC • Provide RFC submission support • Form TWG; set schedule RFC Proposed Standard Technical Note Reject Community Review Stakeholders Evaluate Proposed Standard TWG Evaluate Proposed Standard Implementations and Community Response SPG Recommendation Reject Technical Note Recommended Standard SPG Process Discussion - October 21, 2009

  5. Responsibilities SPG Process Discussion - October 21, 2009 • Community Leader • Identify someone in their community who will document standard according to SPG guidelines. • Work with the community to get an extended review of the proposed standard. • SPG • Assign “RFC editor” to advise on RFC document. • Publish and publicize RFC • Assign “TWG”, technical working group to organize community review and evaluate responses. • Recommend action to NASA HQ.

  6. Endorsed Standards SPG Process Discussion - October 21, 2009 Data Access Protocol (DAP) V2.0 OGC Web Map Service V 1.1.1 HDF 5 HDF EOS 5 NetCDF Classic GCMD DIF

  7. Endorsed Technical Notes SPG Process Discussion - October 21, 2009 OGC Web Map Service V1.3 AURA Guidelines Backtrack Orbit Search Algorithm Interoperability Between OGC CS/W and WCS Protocols Lessons Learned Regarding WCS Server Deisgn and Implementation Creating File Format Guidelines: The Aura Experience

  8. RFCs Under Review SPG Process Discussion - October 21, 2009 Mapping HDF5 to DAP2 – Technical Note ICARTT RFC – Standards Track ECHO Metadata Model RFC CF Metadata Conventions RFC

  9. Technical Areas for Future RFCs SPG Process Discussion - October 21, 2009 Web Services (e.g. REST, SOAP, ..) Catalog services (e.g. OGC CSW,…) Metadata standards (e.g. ISO 19115,…) Visualization standards (e.g. KML,..) File Formats (e.g. NetCDF4,..) Interface standards (e.g. DAP v4, …) Data modeling Data Fusion

  10. Decadal Survey Mission Perspective SPG Process Discussion - October 21, 2009 Identify technical areas where (additional) standards are needed Identify technical areas of interest for future RFCs Discussion : What are the barriers to using the endorsed standards by the DS teams Identify how the DS mission data system teams can work with the SPG to submit future RFCs SPG participation by the DS teams

  11. Next Steps SPG Process Discussion - October 21, 2009 Recommend a process on producing a reference architecture for the DS mission data systems Identify the core standards for the DS mission data systems Identify the standards gaps where standards are needed What are the SPG actions needed to support the DS mission data systems

  12. SPG Standards http://www.esdswg.org/spg Recommended for Endorsement SPG Process Discussion - October 21, 2009
