The Unified Metadata Model Variable Profile (UMM-Variable) is a NASA recommendation for describing Variable Metadata in NASA's Common Metadata Repository (CMR). This profile includes the concepts that NASA considers important for describing dataset variables.
UMM-Variable Required
| Concept | Description | Dialect (Fit) Paths |
|---|---|---|
| Name | The name of a variable. | ISO /gmi:MI_Metadata/gmd:contentInfo/*/gmd:dimension/gmd:MD_Band/gmd:sequenceIdentifier/gco:MemberName/gco:aName/gco:CharacterString ISO-1 /mdb:MD_Metadata/mdb:contentInfo/*/mrc:attributeGroup/mrc:MD_AttributeGroup/mrc:attribute/mrc:MD_SampleDimension/mrc:sequenceIdentifier/gco:MemberName/gco:aName/gco:CharacterString ECHO /echo:Granule/MeasuredParameters/echo:MeasuredParameter/echo:ParameterName |

| DataType | The data type of a variable. These types can be either: uint8, uint16, etc. | ISO /gmi:MI_Metadata/gmd:contentInfo/*/gmd:dimension/gmd:MD_Band/gmd:sequenceIdentifier/gco:MemberName/gco:attributeType/gco:TypeName/gco:aName/gco:CharacterString ISO-1 /mdb:MD_Metadata/mdb:contentInfo/*/mrc:attributeGroup/mrc:MD_AttributeGroup/mrc:attribute/mrc:MD_SampleDimension/mrc:sequenceIdentifier/gco:MemberName/gco:attributeType/gco:TypeName/gco:aName/gco:CharacterString ECHO /*/echo:AdditionalAttributes/echo:AdditionalAttribute/DataType |
| DimensionsName | The names of the dimensions of the variable represented in the data field. For example: 1200, 1200. This is sourced from the granule header. See the dimensions section. | ISO /gmi:MI_Metadata/gmd:contentInfo/*/gmd:dimension/gmd:MD_Band/gmd:sequenceIdentifier/gco:MemberName/gco:aName/gco:CharacterString ISO-1 /mdb:MD_Metadata/mdb:contentInfo/*/mrc:attributeGroup/mrc:MD_AttributeGroup/mrc:attribute/mrc:MD_SampleDimension/mrc:sequenceIdentifier/gco:MemberName/gco:aName/gco:CharacterString ECHO /*/echo:AdditionalAttributes/echo:AdditionalAttribute/Name |
| Dimensions | The values of the dimensions of the variable represented in the data field. For example: 1200, 1200. This is sourced from the granule header. See the dimensions section. | ISO /gmi:MI_Metadata/gmd:contentInfo/gmd:MD_CoverageDescription/gmd:dimension/gmd:MD_Band/gmd:otherProperty/gco:Record/eos:AdditionalAttributes/eos:AdditionalAttribute[eos:reference/eos:EOS_AdditionalAttributeDescription/eos:name/gco:CharacterString='Dimensions']/eos:value/gco:CharacterString ISO-1 /mdb:MD_Metadata/mdb:contentInfo/*/mrc:attributeGroup/mrc:MD_AttributeGroup/mrc:attribute/mrc:MD_SampleDimension/mrc:otherProperty/gco:Record/mrc:AdditionalAttributes/mrc:AdditionalAttribute[mrc:reference/mrc:EOS_AdditionalAttributeDescription/mrc:name/gco:CharacterString='Dimensions']/mrc:value/gco:CharacterString ECHO /*/echo:AdditionalAttributes/echo:AdditionalAttribute/echo:Value |
| ValidRange | Valid range data value of a variable: minimum and maximum values. For example: 7500, -1, or 0, 377 | ISO /gmi:MI_Metadata/gmd:contentInfo/*/gmd:dimension/gmd:MD_Band/gmd:minValue/gco:Real ISO /gmi:MI_Metadata/gmd:contentInfo/*/gmd:dimension/gmd:MD_Band/gmd:maxValue/gco:Real ISO-1 /mdb:MD_Metadata/mdb:contentInfo/*/mrc:attributeGroup/mrc:MD_AttributeGroup/mrc:attribute/mrc:MD_SampleDimension/mrc:minValue ISO-1 /mdb:MD_Metadata/mdb:contentInfo/*/mrc:attributeGroup/mrc:MD_AttributeGroup/mrc:attribute/mrc:MD_SampleDimension/mrc:maxValue ECHO /*/echo:AdditionalAttributes/echo:AdditionalAttribute/echo:ParameterRangeBegin ECHO /*/echo:AdditionalAttributes/echo:AdditionalAttribute/echo:ParameterRangeEnd |
| Scale | Scale factor which has been applied to the cell value. For example: 0.002 | ISO /gmi:MI_Metadata/gmd:contentInfo/*/gmd:dimension/gmd:MD_Band/gmd:scaleFactor ISO-1 /mdb:MD_Metadata/mdb:contentInfo/*/mrc:attributeGroup/mrc:MD_AttributeGroup/mrc:attribute/mrc:MD_SampleDimension/mrc:scaleFactor ECHO |
| Offset | The physical value corresponding to a cell value of zero. For example: 0.49 | ISO /gmi:MI_Metadata/gmd:contentInfo/*/gmd:dimension/gmd:MD_Band/gmd:offset ISO-1 /mdb:MD_Metadata/mdb:contentInfo/*/mrc:attributeGroup/mrc:MD_AttributeGroup/mrc:attribute/mrc:MD_SampleDimension/mrc:offset ECHO |
| FillValue | The fill value of the variable in the data file. It is generally a value which falls outside the valid range. For example, if the valid range is 0, 360, the fill value may be 377 | ISO /gmi:MI_Metadata/gmd:contentInfo/gmd:MD_CoverageDescription/gmd:dimension/gmd:MD_Band/gmd:otherProperty/gco:Record/eos:AdditionalAttributes/eos:AdditionalAttribute[eos:reference/eos:EOS_AdditionalAttributeDescription/eos:name/gco:CharacterString='FillValue']/eos:value/gco:CharacterString ISO-1 /mdb:MD_Metadata/mdb:contentInfo/*/mrc:attributeGroup/mrc:MD_AttributeGroup/mrc:attribute/mrc:MD_SampleDimension/mrc:otherProperty/gco:Record/mrc:AdditionalAttributes/mrc:AdditionalAttribute[mrc:reference/mrc:EOS_AdditionalAttributeDescription/mrc:name/gco:CharacterString='FillValue=']/mrc:value/gco:CharacterString ECHO |
| VariableType | This element is used to identify the variable as a Science Variable or as a Quality Variable or as an Ancillary Variable. If a variable does not contain this field, it will be assumed to be a science variable. | ISO /gmi:MI_Metadata/gmd:contentInfo/*/gmd:contentType/gmd:MD_CoverageContentTypeCode ISO-1 /mdb:MD_Metadata/mdb:contentInfo/*/mrc:attributeGroup/mrc:MD_AttributeGroup/mrc:contentType/mrc:MD_CoverageContentTypeCode ECHO |
| Theme Keyword | A word or phrase that describes some aspect of a resource. Can be one of several types. Note: The general identification keywords usually have a type of "theme" and are refered to as "theme keywords". Other types and vocabularies are used for other information. Service Entry Resource Format (SERF) requires a Science and a Service GCMD Keyword. This concept is called Subject in the CSW Specification. | ISO /*/gmd:identificationInfo/*/gmd:descriptiveKeywords/gmd:MD_Keywords[normalize-space(gmd:type/gmd:MD_KeywordTypeCode)='theme']/gmd:keyword//* ISO-1 /mdb:MD_Metadata/mdb:identificationInfo/*/mri:descriptiveKeywords/mri:MD_Keywords[normalize-space(mri:type/mri:MD_KeywordTypeCode)='theme']/mri:keyword//* |
