Summary

These documents contain This section contains a series of recommendations made by NASA's Earth Science Data System Working Groups (ESDSWG) Dataset Interoperability Working Group (DIWG) that are meant intended to increase and enhance the interoperability of Earth Science data product files. The DIWG recommendations herein embody best practices to reduce and bridge gaps between geoscience dataset formats widely used at NASA and elsewhere and to help ensure that Earth science datasets smoothly interoperate with each other regardless of their origin.

The first document, Dataset Interoperability Recommendations for Earth Science, was published in July 2016 and contains 12 recommendations. The second, Dataset Interoperability Recommendations for Earth Science: Part 2, was published in April 2019. These are a continuation of the 2016 recommendations with the same goal of improving the interoperability of Earth Science dataset files. Most cover new areas of interoperability while some expand on the 2016 recommendations.

(RFC-036)

• Character set for user-defined group, dataset, and attribute names
• Consistent units attribute value for variables across one data collection
• Use the units attribute only for variables with physical units
• Include time coordinate in swath structured data
• Keep coordinate values in coordinate variables
• Include Georeference Information with Geospatial Coordinates
• Not-a-Number (NaN) Value
• Standardize file extensions for HDF5/netCDF files
• Ensure Granule's Filename Uniqueness Across Different Dataset Releases
• Adopt Semantically Rich Dataset Release Identifiers
• Date-Time Information in Granule Filenames
