The Collection Progress element describes the production status of the dataset. The Collection Progress element leverages a controlled vocabulary to ensure consistency across CMR. There are four possible choices for describing the status of the dataset:
For continuous datasets:
If data collection is ongoing and the Collection Progress element is set to “ACTIVE”, the following actions are recommended:
Setting the ‘Ends at Present Flag’ element to “true” tells the CMR that the ending time for the collection is present day, and thus eliminates the need to specify the ending date time of the collection. This also eliminates the need to update the ending date time in the metadata each time new data gets added to the collection.
For completed datasets:
If data collection is complete and the collection progress is set to “COMPLETE”, the following actions are recommended:
Setting the ‘Ends at Present Flag’ element to “false” tells the CMR that the ending time for the collection is in the past. If the temporal extent of the collection is expressed as a range date time, then the “Ending Date Time” element should specify the ending date and time of the last available granule in the collection.
For disparate datasets:
For some datasets, there may be gaps in data collection. For example, there may be a flight campaign dataset where data is only collected in May and September of each year. If there are future plans to add data to the collection, then it is okay to set the Collection Progress to “ACTIVE”. In this scenario, opposite to the best practices specified for continuous datasets above, it is recommended that the ‘Ends At Present Flag’ be set to “false” and that and Ending Date time be provided. This would require that the Ending Date Time be updated each time new data gets added to the collection (e.g. in May and September). This practice most accurately conveys the temporal coverage of a dataset to a user.

Value needed for translations:
The following value is needed by the CMR to translate older non UMM compliant records to and from the UMM and other supported specifications where non required elements are considered required but no valid is given. This is needed partly because the CMR still allows a non UMM compliant record to be ingested with warnings.
NOT PROVIDED - It is necessary for this value to exist so that the CMR can translate older non UMM compliant records into the latest UMM specification where CollectionProgress is required. This value should not be used by metadata providers.
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).
