Maintenance Frequency Best Practices

This FGDC conformance check verifies the existence of a Maintenance Frequency Code in an ISO 19115 or 19115-3 metadata record. From the FGDC guidance:

MD_MaintenanceFrequencyCode is the frequency with which modifications and deletions are made to the data after it is first produced.

Metadata creators should include one of the several Maintenance Frequency Codes within this element: MD_MaintenanceFrequencyCode

If frequency code is set to asNeeded or notPlanned, then the status>MD_ProgressCode element should use the value ‘completed’.

Best Practices

  • If more than one Maintenance Frequency Code is specified, the value with the greatest range will be used. Example, annually takes precedent over weekly .

    • asNeeded or notPlanned codes will also need a Status Progress Codes of completed .
