Element Description
Note: This wiki page is a draft/ still in progress
This wiki page is for Data Center elements only
Create a separate page for DataCenter/ContactPerson elements & DataCenter/ContactGroup elements
The Data Center metadata element is used to identify entities responsible for originating, processing, archiving, and/or distributing the data set described in the metadata. The Data Center elements can also be used to provide the address of the data center and any relevant contact information.
There are two separate sub-sections within Data Center which can be used to provide contact information for an individual person or group from a data center rather than the data center as a whole. Specifications for these metadata fields can be found on the DataCenter/ContactPerson wiki page and on the DataCenter/ContactGroup wiki page.

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.

This element is categorized as highest priority when:
- No Related URLs are provided
- No data access URL is provided. For further details on data access URLs please see the Related URLs (GET DATA) wiki page.
- There is a service available for a collection, but no service URL is provided. For further details on service URLs please see the Related URLs (USE SERVICE API) wiki page.
- The URL provided is broken
- The URL provided is incorrect/ unrelated to the associated data set
- The URL Type or Subtype provided does not accurately describe the link (i.e. the link is mislabeled)
- The URL Type or Subtype provided does not align with the KMS
- The Type or Subtype does not exist in the KMS
- The Type or Subtype is placed in the incorrect position of the hierarchy (e.g. GET DATA should not be provided in the Subtype field, because it is categorized as a Type keyword in the KMS)
- There is an invalid Type/Subtype relationship (e.g. Type: GET DATA, Subtype: USER'S GUIDE, is not a valid combination in the KMS)
- The URL links to an FTP server (this only applies to NASA EOSDIS metadata)
This element is categorized as medium priority when:
- The 'Description' element is left blank. It is highly recommended that a description be provided for each URL.
- A recommendation is made to change a valid URL Type or Subtype keyword for purposes of consistency with other similar metadata records
- The URL provided in the metadata redirects - it is recommended that the most current link always be provided
- A noted exception to this is DOI URLs (e.g. https://doi.org/10.3334/ORNLDAAC/1416) since these will always re-direct
This element is categorized as low priority when:
- The 'Description' element is identical for multiple URLs
- If a recommendation is made to add a URL to the metadata, there will be accompanying blue recommendations to add the appropriate URL Content Type/ URL Type/ Subtype elements.
- A URL is provided via http when https is available
ARC Automated Rules
- If no value is provided, return is: "Recommend providing a Related URL. This is a required field."
- If a value is provided, the URL is put through a URL checker:
- Checks if the link starts with 'https'
- Checks for https return status codes (200, 302, 400, 403, 404, 500, 502, 503, 504)
- If all checks are passed, return is: "OK"
