Data Dates

Element Description

Note: This wiki page is a draft/ work in progress

Data Dates is comprised of dates for when the data or resource itself changed in some way. This element is made of two sub-elements, type and date. The type describes what the date represents: a future review, when the resource was created, last updated, or planned for deletion. The date describes when the resource had an action performed on it or when the action will occur as described by the type element.

Best Practices

The Creation, Last Revision, Future Review, and Planned Deletion dates exist in various places in the different standards.

All data dates have been consolidated under this element. They will be typed and will all be represented by the ISO 8601 date and time conventions as part of the reconciliation process. In DIF 10 both the metadata and data dates are located under the DIF/Metadata_Dates element. The difference is that the sub-elements of Metadata_Creation, Metadata_Last_Revision, Metadata_Future_Review, and Metadata_Delete describe the metadata dates and the sub-elements of Data_Creation, Data_Last_Revision, Data_Future_Review, Data_Delete describe the resource dates.

Examples:

Type=CREATE: 2010-02-01

Type=UPDATE: 2018-02-01

Type=REVIEW: 2019-02-01

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).

Please see the expandable sections below for flowchart details.
