Element Description
The archive and distribution information main element allows data providers to provide users information of what is available for downloading when they are initially looking at a collection. The end users get information such as the average downloadable file size, format, mime type, checksum, an estimate of the collection's entire downloadable file size, etc.
Best Practices
There are multiple sub-elements that comprise Archive and Distribution Information for Collections:
Format: Defines a single format for an archival artifact (e.g., binary, jpeg, HDF5, HDF-EOS5, geotiff)
Format Type: Allows the provider to define if the archival artifact's format is in its native format or another supported format
Average File Size: An approximate average of the size of the the archivable item, which gives users an idea of the magnitude of each archivable file
Average File Size Unit: Unit of measure for the average file size (e.g., KB, MB, TB)
Total Collection File Size: An approximate total size of the archivable items, which gives users an idea of the magnitude of all the archivable files combined
Total Collection File Size Unit: Unit of measure for the total collection file size (e.g., KB, MB, TB)
Description: Enables the provider to provide more information about the archivable item

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.
- Manual Review
- Identify errors, discrepancies or omissions.
- Verify that all pertinent keywords have been applied.
- Verify that existing facets and other controlled keyword values are consistent and suitable for the data.
- Automated Review
- Check that the field has been populated.
- Check that the field is populated with a valid value from KMS.
- Check that the field value is not a duplicate.
- Check that the field length is not greater than the maximum characters allowed for each sub-element.
- Check that the field '/Instrument/NumberOfSensors' is an integer value.
- The specific instrument must be unique within the collection. The uniqueness is established by combining the instrument short name along with its characteristic's name.
- The instrument short name must match with what is in the KMS.
- If a granule has an instrument short name in it, it must match to one that is defined in the collection.
- If removing an instrument from a collection, none of its granules can reference that instrument's short name.

Instrument is an optional metadata element, however, it is strongly recommended that it be provided when possible. Multiple Instruments may be listed if necessary (Cardinality: 0..*).
Providing instrument characteristics is optional. An unlimited amount of instrument characteristics may be specified for a particular instrument (Cardinality: 0..*). If instrument characteristics are provided, all 5 sub-fields (Name, Description, DataType, Unit, Value) are required.
UMM-C Element | Path | Type | Notes |
---|---|---|---|
Platforms/Instruments/ShortName | /mdb:MD_Metadata/mdb:acquisitionInformation/mac:MI_AcquisitionInformation/mac:instrument/mac:MI_Instrument id="<insert unique instrument ID here>"/mac:identifier/mcc:MD_Identifier/mcc:code/gco:CharacterString with /mdb:MD_Metadata/mdb:acquisitionInformation/mac:MI_AcquisitionInformation/mac:instrument/mac:MI_Instrument id="<insert unique instrument ID here>"/mac:identifier/mcc:MD_Identifier/mcc:codeSpace/gco:CharacterString = gov.nasa.esdis.umm.instrumentshortname | String | Corresponds to the UMM field Platforms/Instruments/ShortName. A list of valid instrument short names can be found in the KMS under the 'Short_Name' column. For each instrument listed the short name is required by CMR. The short name value goes in the gmd:code field. The value of " gov.nasa.esdis.umm.instrumentshortname" should be provided in gmd:CodeSpace field so that CMR can properly parse out the instrument short name. An ID should be provided directly after "eos:EOS_Instrument" in the ISO x-path. This ID corresponds to the instrument and is used to link the instrument information to the associated platform. The ID should be unique within the metadata record. |
Platforms/Instruments/LongName | /mdb:MD_Metadata/mdb:acquisitionInformation/mac:MI_AcquisitionInformation/mac:instrument/mac:MI_Instrument id="<insert unique instrument ID here>"/mac:identifier/mcc:MD_Identifier/mcc:description/gco:CharacterString | String | Corresponds to the UMM field Platforms/Instruments/LongName. A list of valid instrument long names can be found in the KMS under the 'Long_Name' column. |
Platforms/Instruments/Technique | /mdb:MD_Metadata/mdb:acquisitionInformation/mac:MI_AcquisitionInformation/mac:instrument/mac:MI_Instrument id="<insert unique instrument ID here>"mac:type/gco:CharacterString | String | Corresponds to the UMM field Platforms/Instruments/Technique. |
Platforms/Instruments/NumberOfInstruments | When translating to UMM-C the number of instruments is counted. The number is not translated to ISO 19115-2 MENDS | Corresponds to the UMM field Platforms/Instruments/NumberOfInstruments. | |
/mdb:MD_Metadata/mdb:acquisitionInformation/mac:MI_AcquisitionInformation/mac:instrument/mac:MI_Instrument id="<insert unique instrument ID here> "/mac:otherProperty/gco:Record/eos:AdditionalAttributes/eos:AdditionalAttribute/eos:reference/eos:EOS_AdditionalAttributeDescription/ eos:type/eos:EOS_AdditionalAttributeTypeCode codeList="https://cdn.earthdata.nasa.gov/iso/resources/Codelist/gmxCodelists.xml#EOS_AdditionalAttributeTypeCode" codeListValue="instrumentInformation" = instrumentInformation | Codelist | The "instrumentInformation" codelist value must be provided so that CMR can properly identify the associated information as instrument characteristics. This codelist value does not directly map to a UMM element—choosing 'instrumentInformation' indicates to CMR that the instrument characteristic elements should be mapped. | |

ISO codelist values (class, codelist, enumeration, codelistElement, abstractClass, aggregateClass, specifiedClass, datatypeClass, interfaceClass, unionClass, metaClass, typeClass, characterString, integer, association) UMM enum (STRING, FLOAT, INT BOOLEAN, DATE, TIME, DATETIME, DATE_STRING, TIME_STRING, DATETIME_STRING) |

The eos:name field must read "OperationalMode" so that CMR can properly parse out the operation mode information. The actual operation mode value should be provided in the eos:value field. |
/mdb:MD_Metadata/mdb:acquisitionInformation/mac:MI_AcquisitionInformation/mac:instrument/mac:MI_Instrument id="<insert unique instrument ID here>/gmi:mountedOn xlink:href='<insert unique platform ID here>' | An ID should be provided here and should match the ID provided for the associated platform. This ID should be unique within a metadata record. This will link all of the information provided on the instrument to its associated platform. |
