Archive and Distribution Information for Collections

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)

Total Collection File Size Begin Date: The date that data collection began for the collection, which should be in the following format: yyyy-MM-ddTHH:mm:ssZ

Description: Enables the provider to provide more information about the archivable item

Media: Defines how the distributable material can be obtained by an end user (e.g., CD-ROM, hard drives, online, etc.)

Fees: Provide the price an end user will need to pay in order to obtain the distributable material

Examples:

Format Type: "Native"

Average File Size: "250"

Average File Size Unit: "KB"

Total Collection File Size: "25"

Total Collect File Size Unit: "GB"

Total Collection File Size Begin Date: "2018-04-01T00:00:00Z"

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.

GCMD Metadata QA/QC

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.

CMR Validation

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.

ISO 19115-1

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.

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.
