SPG Mission

The mission of the NASA Earth Science Data Systems (ESDS) Standards Process Group (SPG) is to foster the use of proven data system standards for both producers and users of NASA data products and services, thereby facilitating the efficient exploration, discovery, and prudent preservation of NASA Earth science data.

Through a community-based review and vetting process, the SPG provides the means for NASA stakeholders to designate preferred standards and other practices that will advance NASA’s Earth science mission through improved utilization of its resources. The SPG also seeks to identify areas of data production and management where standardization would increase the ability of the science community to use NASA Earth science data and to promote development of valuable new standards.

DAP-2 Implementation Review Summary

Spec reviews:

Organization: JPL, server developer, points out some info that is lacking in spec, and some potential limitations. More...
Organization: GMU 2 recs for spec (1) add query method for DAP client to identify datasets server is holding, and (2) clarify how ints & bytes are encoded (this encoding clarification is something James Gallagher noted needs to be done). More...
Organization: GMU - installed several servers & one DAP client, ingested metadata from DAP servers for supporting metadata search and DAP URL generation. Has several recs for improving the spec her suggestions need to be discussed with James. More...
Organization: IRI has general operational experience as well as several detailed comments about protocol. Identifies some weaknesses. Overall positive. More...
Organization: SCCWRP - spec & some operational experience. Group installed servers and developed own DAP client. Identifies one weakness (no way to handle time values). Overall positive. More...
Organization: UAH/ITSC server development experience & some operational experience. Extended current servers to use ESML to support heterogeneous data formats. Overall positive. More...
Organization: SDSC implemented driver that allows a DAP server to use the SRB (Storage Resource Broker) as a data storage system. With this driver, DAP Servers uses the files stored in SRB as if they were stored on local disk. Overall positive. More...

Operational experience reviews:

Organization: SEACOS/SC SEACOOS OPeNDAP dialog multiple people in the SEACOOS group wrote about their operational experience. More...
Organization: USGS - servers worked okay but had trouble building own client. More...
Organization: DLESA Data Access Working Group for Digital Library for Earth Systems Education has recommended that OPeNDAP be supported in future efforts to supply earth science data to education. More...
Organization: US JGOFS DMO - US Joint Global Ocean Flux Study Data Management Office The US JGOFS LAS is here: http://usjgofs.whoi.edu/las -- positive experience. More...
Organization: IOUSP - oceanography professor at Oceanographic Inst of the Univ of Sao Paulo(IOUSP) and helping Paulo Nobre from the National Institute for Space Research (INPE) in Brazil. More...
Organization: CLS/ARGOS - Direction Oceanographie Spatiale/Departement Produits et Servcices , France. Overall positive experience. More...
Organization: IAC - Institute for Atmospheric and Climate Science (IAC), Swiss Federal Institute of Technology, Switzerland. Used servers to share data among a group of atmospheric chemistry modelers. Tried to implement own IDL client but was unsuccessful. Tried to reuse much existing software & libraries for client development but had problems. Overall positive experience with servers. More...
Organization: NCDC/NOMADS - modeling portal. Overall positive experience installing and running servers. More...
Organization: SSEC - Unidata User committees Technical Advisor, University of Wisconsin-Madison, Space Science and Engineering Center, Cooperative Institute for Meteorological Satellite Studies. Overall positive. Makes some points on the benefits of adopting one standard for accessing data. More...
