Element Description

The Purpose element contains suggested usage for the data and/or a description for why the resource exists. Any limitations on the resource (including, but not limited to, special restrictions, legal prerequisites, and terms and conditions) should be placed into the Use Constraints element and not into the Purpose element.

Best Practices

The Purpose element is optional. It can be leveraged to communicate to a user specific the broad applications the data is designed to be used for, and/or why the data were generated. 

Examples:

"To assess species composition, abundance, distribution and biomass of zooplankton within the Bering and Chukchi Seas, 1985-1989."

"To provide VIIRS 375m resolution active fire locations in Near Real-Time in easy to use formats."

"To serve a wide user community by providing composite Landsat images and raw data for urban areas that can be used in interdisciplinary studies of remote sensing and the environment."

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).

  • Manual Review
    • Check that the purpose description is appropriate for the dataset.
  • Automated Review
    • Check that the field has been populated.
    • Check that the field length is not greater than 1000 characters.

ARC Priority Matrix

Priority CategorizationJustification

Red = High Priority Finding

This element is categorized as highest priority when:

  • The purpose Purpose contains spelling or grammatical errors.
  • The purpose Purpose is incorrect for the data (for example, a copy + and paste error could result in the purpose for a different dataset to appear in this field).
  • A broken URL is provided in the purpose Purpose element.

Yellow = Medium Priority Finding

This element is categorized as medium priority when:

  • The information provided in the purpose Purpose element is better suited for a different metadata field (i.e. incorrect usage of the purpose Purpose field).

Blue = Low Priority Finding

This element is categorized as low priority when:

  • A link provided in the purpose Purpose element needs to be updated from 'http' to 'https'.

Green = No Findings/Issues

The element is provided , and follows all applicable criteria specified in the best practices section above.

ARC Automated Rules

If novalue is provided, return is "np"
  • Otherwise, return is "OK"

    • Checks

    ARC uses the pyQuARC library for automated metadata checks. Please see the pyQuARC GitHub for more information.
