Hi Jennifer, > First, I want to thank you very much for answering all of my questions > on the NetCDF-4 standard and helping me prepare a package to submit > this as a standard in the Department of Defense Information Technology > Standards Registry (DISR).

I am hoping one of you might be able to help > (see attached email). It all boils down to: > > 1. What standards body developed and now maintains this standard? We (UCAR) develop and maintain the software, but several organizations and standards bodies have endorsed its use, including NASA, OGC, and FGDC. For more information on these endorsements, see: http://www.unidata.ucar.edu/netcdf/docs/standards.html OGC maintains their versions of netCDF standards, which were adapted from the NASA standards. In addition, these Library of Congress descriptions, which they maintain, include official information about the standards status of three netCDF format variants: NetCDF-3, Network Common Data Form, version 3 http://www.digitalpreservation.gov/formats/fdd/fdd000330.shtml NetCDF-4, Network Common Data Form, Version 4 http://www.digitalpreservation.gov/formats/fdd/fdd000332.shtml NetCDF-4C, Network Common Data Form, Version 4, Classic Model http://www.digitalpreservation.gov/formats/fdd/fdd000339.shtml > 2. Is it an international, national, or military standard? FGDC's endorsement is as a national standard. The NASA and OGC standards are used internationally. > 3. Is an open process used to develop and maintain this standard? The OGC and NASA processes are open. I don't know what FGDC's process was. The Library of Congress openly solicited comments on their descriptions of the formats. > They don't believe that UCAR is a standards development organization > (maybe they are correct) and they say "You need to convince us". Is > there any documentation that supports UCAR being a standards body? No, UCAR is a nonprofit consortium of research universities that serves as a hub for research, education, and public outreach for the atmospheric and related Earth sciences community. Among its many activities is the development of software and infrastructure that may be adopted for use by other organizations and that may be endorsed as standards for more general use. That's how netCDF became a standard. --Russ > Frank, > > Do you know if someone at Navy is currently participating in the > development and/or maintenance process?
