Element Description

The Granule UR element provides the universal reference identifier of the granule, which is assigned by the data provider. The Id should be unique per data provider. 


Best Practices

Typically, the Granule UR will match the granule's file name. However, other identifying information may be included. The UR must be completely unique when compared to all other data from the same provider (i.e. datasets with the same provider Id in CMR).  

Examples:

Granule UR: AIRS2CCF_NRT.006:AIRS.2018.10.18.189.L2.CC_IR.v6.0.31.0.R18291162512.hdf

Granule UR: MA_AMSUA_NOAA17_OMF.001:merra.mon_stdv3d_amsua_noaa17_omf.200212_06z.nc

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).

Please see the expandable sections below for flowchart details.

ARC Priority Matrix

Priority CategorizationJustification

Red = High Priority Finding

This element is categorized as highest priority when:

  • No Granule UR is provided.
  • The Granule UR is incorrect for the granule.

Yellow = Medium Priority Finding

Not Applicable

Blue = Low Priority Finding

Not Applicable

Green = No Findings/Issues

The element is provided and follows all applicable criteria specified in the best practices section above.

ARC Automated Checks

ARC uses the pyQuARC library for automated metadata checks. Please see the pyQuARC GitHub for more information.

String

Provide the GranuleUR in the gmd:code field.

Provide the string"gov.nasa.esdis.umm.granuleur" in the gmd:codeSpace field. The CMR will use this string to parse out the appropriate GranuleUR value.

Also provide the string "GranuleUR" in the gmd:description field. The CMR will use this string to parse out the appropriate GranuleUR value.
