Element Description
Spatial Extent-Track is a recently added element that will be assigned at the granule level only. The first campaign that will use this element will be the Surface Water and Ocean Topography, or SWOT, mission managed by PO.DAAC. However, it will eventually be expanded to other future projects.
Best Practices
In an effort to make searching for data easier, granules will eventually have the ability to be searched by their orbit information using the following terms: cycle, pass, and tiles. A cycle will encompass data from a days worth of orbits while a pass will only be a half-orbit.
Examples:

Metadata Validation and QA/QC
All metadata entering the CMR goes through the below process to ensure metadata quality requirements are met. All records undergo CMR validation before entering the system. The process of QA/QC is slightly different for NASA and non-NASA data providers. Non-NASA providers include interagency and international data providers and are referred to as the International Directory Network (IDN).
