Element Description

The Metadata Specification element requires the user to add in schema information into every granule record. It includes the schema's name, version, and URL location. 

Best Practices

The information provided in this element is controlled through enumerations.

There are three sub-elements that comprise the Metadata Specification element:

• URL: This element provides the URL where the schema lives or where the schema can be downloaded.
• Name: This element provides the name of the schema.
• Version: This element provides the version of the schema.

Example:

   "MetadataSpecification": [
           {
               "URL": "https://cdn.earthdata.nasa.gov/umm/granule/v1.6.5",
               "Name": "UMM-G",
               "Version": "1.6.5"
           }
   ],

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).
