AB: The purpose of NASA's Standards Process Group (SPG) is to provide recommendations to NASA management on ways to evolve and improve Earth Data Systems through the endorsement of Earth science data systems standards. SPG's goal is to facilitate broader use of standards that have proven implementation and operational benefit to NASA Earth science by facilitating the approval of proposed standards and directing the evolution of standards. We have found that the candidate standards that self defined communities are proposing for endorsement to the SPG are one of 4 types: (1) A NASA community developed standard used within at least one self defined community where the proposed standard has not been approved or adopted by an external standards organization and where new implementations are expected to be developed from scratch, using the proposed standard as the implementation specification; (2) A NASA community developed standard used within at least one self defined community where the proposed standard has not been approved or adopted by an external standards organization and where new implementations are not expected to be developed from scratch but use existing software libraries or code;. (3) A standard already approved by an external standards organization but is being proposed for use for the NASA Earth science community; (4) A defacto standard already widely used. SPG's standards process has been revised to provide a comprehensive but not a redundant review of the proposed standard. We will discuss real examples of the different types of candidate standards that have been proposed and endorsed (i.e. OPeNDAP's Data Access Protocol, Open Geospatial Consortium's Web Map Server, and the Hierarchical Data Format). We will discuss the potential defacto standards (Google's KML, Global Change Master Directory (GCMD) Directory Interchange Format (DIF), GeoTIFF file format) that could be identified and endorsed through our revised Standards Process in the future. We will discuss the issues with the original Standards Process that arose, and the modifications to the Standards Process that we are envisioning as a result of our experience.
