Additional Attributes

Element Description

This entity stores the data's distinctive attributes (i.e. attributes used to describe the unique characteristics of the resource which extend beyond those defined in this mapping).

Best Practices

ECHO 10 uses AdditionalAttributes to describe the data represented in each granule within a collection. These values are important search criteria for the granules. Example attributes include values for cloud cover, MODIS Tile grid coordinates, and elevation information. All additional attribute definitions are included in the collection metadata. A collection may also specify a value, to be understood as the value for all granules. Granules reference defined additional attributes and supply a value that is associated to that granule. Granules may not define a new additional attribute that is not defined by the collection. DIF 10 has additional attributes and is directly mappable. If the additional attribute type is known it can be mapped to the correct section of ISO. Currently additional attributes are mapped to several sections within ISO depending if the attribute is geographical, describes coverage, describes data quality, describes acquisition, or maps to a keyword.

There are fourteen sub-elements that comprise Collection Citations:

Name:

Type:

Identifier:

Data Type: This entity contains the additional attribute data types.

Description: Free-text description of the additional attribute.

Measurement Resolution: The smallest unit increment to which the additional attribute value is measured.

Parameter Range Begin: The minimum value of the additional attribute over the whole collection.

Parameter Range End: The maximum value of the additional attribute over the whole collection.

Parameter Units Of Measure: The standard unit of measurement for the additional attribute. For example: meters, hertz.

Parameter Value Accuracy: An estimate of the accuracy of the values of the additional attribute. For example, for AVHRR: Measurement error or precision-measurement error or precision of a data product parameter. This can be specified in percent or the unit with which the parameter is measured.

Value Accuracy Explanation: Describes the method used for determining the parameter value accuracy that is given for this additional attribute.

Value: Value of the additional attribute if it is the same for all granules across the collection. If the value of the additional attribute may differ by granule, leave this collection-level value blank.

Group: Identifies a namespace for the additional attribute name.

Update Date: The date this additional attribute information was updated.

Examples:

Group: "gov.nasa.gsfc.gcmd"

Value: "42a420d8-04bd-4b2f-ad2a-8adc138faa04"

Name: "metadata.uuid"

Description: "Not provided"

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).
