This is the officially endorsed set of EOSDIS approved standards.
Each document that is submitted to the SPG for processing is called a "Request For Comment" document or RFC. The RFC number remains constant throughout the process and thus serves as a convenient shorthand for the standard.
This table lists all RFC's, either in-process or final.
- Each RFC receives a number. Once approved as "Final", the RFC text is never changed in a substantive way. Editorial changes are collected in an errata document until the RFC Editor and the Standards Process Group decide to update the document. Technical changes would require that a new RFC number be issued and the new RFC would need to be submitted as a new RFC.
- Clicking on the title will lead you directly to the RFC document or to a folder containing the document.
- Revision numbers beginning with "0." are for in-process RFCs. Revision 1 is for Final RFCs. Other revision numbers will be assigned if the document is changed.
- Technical Notes are informational notes. Standards Track documents are in-process to become standards. Standards are final standards.
- Draft means the document is being reviewed. Pending means the document is awaiting final approval. Final means the document has passed through the entire process successfully.
- If "yes", clicking on the link leads to the errata document for the RFC.
These interfaces and data formats were in use by NASA Earth Science Data Systems prior to the start of the ES Data Systems SPG. Some of these have also been submitted to the SPG as an RFC and are included in both this list and the RFC list above. The "Heritage Standards Process" provides a good starting point to learn about these standards.
- Responses to Standards Question - To start the Standards Process, the SPG invited the Earth Science Data community to identify interfaces that would benefit from standardization. This document lists the responses gathered. Contents are taken directly from the original responses.
