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"
Note: If using the Metadata Management Tool (MMT) or docBUILDER to curate your collections, this field is auto-populated (using a mapping) at ingest based on the Science Keywords selected.

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).
