ESO Developing and Emerging Standards, Practices, and Technologies Yonsook Enloe, Helen Conover, Allan Doyle ESDIS Standards Office 7/14/ Summer ESIP1

What is the ESO? The ESDIS Standards Office (ESO) assists the ESDIS Project in formulating standards policy for NASA Earth Science Data Systems (ESDS) and coordinates and provides assistance with standards activities within ESDIS. ESO endorsed data format standards are Level 1 requirements for new NASA missions – ESO will maintain and update that list Incorporated into ESDIS for closer ties to NASA Earth Science Data System goals and support for developing standards. Part of the ESDIS Common Metadata Repository (CMR) project team which is integrating ECHO, GCMD, and EMS. 2

ESO Standards Process ESO reviews an existing convention or standard to evaluate the technical value of the specification, determine its fitness for the purpose, confirm that working implementations exist.  Funded mission data systems can use the ESDS recommended standards with high confidence that the specification is accurate and works with NASA data in NASA environments. ESDIS project also needs to support developing and emerging standards to fulfill current and future needs of the NASA Earth science data systems. 3

Simplified Standards Review Process Phase 1 Document Submission Phase 2 Document Editing Phase 3 Community Review Develop idea for standard Contact ESO for initial consultation Write the document (with handy template) Gather names of people/groups who are using the spec Submit to ESO ESO reviews document, helps submitters with formatting, etc. ESO forms a TWG (Technical Working Group) to review the document TWG reviews the document for completeness, provides feedback, helps submitters complete any final edits TWG decides on review strategy (depends on kind of document) TWG develops review questions TWG sends questions to as many reviewers as possible TWG collects & analyzes results TWG makes a recommendation to ESDIS whether to adopt the document as a standard, convention, etc. or not.

Developing/Emerging Standards For developing standards, different kinds of reviews are needed: Provide constructive feedback to the authors of the new specification in interim points in order to improve the quality of the developing standard Evaluate developing standards (even before complete documentation is written) through evaluating a prototype of its capabilities – can provide constructive feedback to the authors and also provide some visibility to the broader Earth science systems community. 5

ESO’s Focus for ESIP What are promising standards and practices being developed by the ESIP community? What data systems technologies and practices are being explored by the ESIP community that could benefit NASA’s EO data systems? Can these practices be documented as A Community Standard or Practice A Technical Note Recommendations 6
