Element Description

The ISO Topic Category element identifies the topic category (or categories) from the EN ISO 19115 Topic Category Code List that pertain to a collection. The ISO Topic Category is a high-level thematic classification to assist in the grouping of and search for available collections.

Best Practices

There are currently 19 ISO Topic Categories. A complete list of the ISO 19115 Topic Category keywords with definitions can be found here: http://wiki.esipfed.org/index.php/ISO_Topic_Categories

Providing an ISO Topic Category keyword is optional. The field may be repeated so multiple ISO Topic Category keywords may be provided if applicable. The spacing and case of the terms are controlled, and therefore should exactly match the terms as they appear in the ISO schema.

Examples:

"society"

"planningCadastre"

"climatologyMeteorologyAtmosphere"

Element Specification

An unlimited amount of Providing an ISO Topic Category keywords is optional. Multiple ISO Topic Categories may be listed provided (Cardinality: 0..*), however, only 19 ISO Topic Categories exist so there should not be more than 19 of these keywords.

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).
