Element Description
The Identifier element holds different types of granule identifiers.
Best Practices
There are three sub-elements that comprise the Data Granule Identifiers:
- Identifier Type: The value for this field must be selected from a list of known identifier types. If the identifier is not included in the list, the enumeration value of "Other" may be selected, and the provider must specify the identifier's name. Available identifiers include:
- ProducerGranuleId
- LocalVersionId
- FeatureId
- CRID
- Other - select "Other" to provide an identifier not included in the list
- Identifier: The identifier value, e.g. the CRID value, FeatureId value, etc.
- Identifier Name: The name of the identifier. This field should only be populated if 'Other' is selected as the identifier type.
Examples:
Identifier Type: "ProducerGranuleId"
Identifier: "MERRA300.prod.assim.tavgU_3d_udt_Cp.200909.hdf"
Identifier Type: "CRID"
Identifier: "R16010"
Identifier Type: "Other"
Identifier: "2013_GR_NASA"
IdentifierName: "ThemeId"
Element Specification
Providing an Identifier is optional. More than 1 different type of identifier may be provided, but each type may only be used once (e.g. only one FeatureId may be provided, only one CRID may be provided, etc.) (Cardinality: 0..1).
Model | Element | Type | Usable Valid Values | Constraints | Required? | Cardinality | Notes |
---|---|---|---|---|---|---|---|
UMM-G | DataGranule/Identifiers/IdentifierType | Enumeration | ProducerGranuleId LocalVersionId FeatureId CRID Other | n/a | Yes, if applicable | 1 | Multiple Identifier Types may be provided, but each enumeration can only be used once in a granule record. |
UMM-G | DataGranule/Identifiers/Identifier | String | n/a | 1 - 1024 characters | Yes, if applicable | 1 | The actual value of the Identifier (e.g. the CRID value, FeatureId value, etc.) |
UMM-G | DataGranule/Identifiers/IdentifierName | String | n/a | 1 - 1024 characters | Only required if "Other" is selected as the IdentifierType | 0..1 | If "Other" is selected as the IdentifierType, then this field must be used to provide a name for the identifier. |
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 inter-agency and international data providers and are referred to as the International Directory Network (IDN).

ECHO 10Providing a Producer Granule Id or Local Version Id is optional in ECHO 10. There are not special fields in ECHO 10 for CRID, FeatureId, or "Other" IDs. It is recommended that other types of granule identifiers be provided in the Additional Attributes metadata element in ECHO 10.
