The Metadata Specification element requires the user to add in schema information into every collection record. It includes the schema's name, version, and URL location.
The information provided in this element is controlled through enumerations.
There are three sub-elements that comprise the Metadata Specification element:
Example:
"MetadataSpecification": [ { "URL": "https://cdn.earthdata.nasa.gov/umm/collection/v1.17.0",
"Name": "UMM-C",
"Version": "1.17.0"
}
],
Metadata Specification is required in the UMM-C (Cardinality: 1).
Model | Element | Type | Constraints | Required? | Cardinality |
---|---|---|---|---|---|
UMM-C | MetadataSpecification/URL | Constant | Yes | 1 | |
UMM-C | MetadataSpecification/Name | Constant | UMM-C | Yes | 1 |
UMM-C | MetadataSpecification/Version | Constant | 1.17.0 | Yes | 1 |
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).
Please see the expandable sections below for flowchart details.
