Data Center

Element Description

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

The Data Center metadata element is used to identify and provide contact information for the organization responsible for originating, processing, archiving, and/or distributing the data set being described in the metadata.

Contact information about an individual or a group affiliated with the data can also be provided. Information about an individual should be provided in the DataCenter/ContactPerson sub-fields. Please see the DataCenter/ContactPerson wiki page for details on the Contact Person metadata elements. Information about a group should be provided in the DataCenter/ContactGroup sub-fields. Please see the DataCenter/ContactGroup wiki page for details on the Contact Group metadata elements. Note that each contact person or group must be affiliated with a Data Center.

Best Practices

Each Data Center listed in the metadata must be affiliated with a Role. Providing a Role for the Data Center is required and must be selected from a controlled vocabulary list. There are four options for Role:

ARCHIVER: the organization responsible for storing the data. This role should be selected when listing the name of a NASA Distributed Active Archive Center (DAAC).
DISTRIBUTOR: the organization responsible for distributing the data. The archiver and distributor will often be the same organization. In this case, both 'ARCHIVER' and 'DISTRIBUTOR' can be specified for the same data center.
ORIGINATOR: the organization responsible for producing the data.
PROCESSOR: the organization responsible for processing the data. Not all data is necessarily processed. Examples of processing include: converting raw data into level 1 data; re-gridding or re-projecting data to make a higher level product; combining multiple data products to derive a model output

The same data center may be responsible for multiple roles. In this case, multiple roles may be assigned to the same data center.

The following elements are also associated with Data Center:

Short Name: The name of the Data Center (abbreviated version). Providing a Data Center Short Name is required. The Data Center Short Name must be selected from a controlled vocabulary maintained in the Keyword Managenemt System (KMS). A list of valid Data Center keywords can be found here: https://gcmdservices.gsfc.nasa.gov/static/kms/providers/providers.csv? Note that the Short Name should be selected from the "Short_Name" column in the keyword list.

Long Name: The name of the Data Center. Providing a Data Center Long Name is optional, however, it is recommended that a long name be provided if one exists in the keyword list since short names are often comprised of acronyms. A list of valid Data Center keywords can be found here: https://gcmdservices.gsfc.nasa.gov/static/kms/providers/providers.csv? Note that the Long Name should be selected from the "Long_Name" column in the keyword list.

Uuid: The uuid is the unique identifier associated with the Data Center name in the controlled vocabulary keyword list. Providing the uuid is completely optional. The uuid can be found in the Data Centers keyword list in the "UUID" column.

Contact Information: Any relevant contact information for the data center can be provided in the Contact Information fields. Providing contact information is optional, however, it is recommended that at least one piece of contact information (such as a link, email or phone number) be provided. Some examples of contact information include: phone number, email, fax, related links, service hours, and contact instructions. See the element specification table below for full details.

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).

Priority Categorization	Justification
	This element is categorized as highest priority when: No Data Center information is provided No Data Center Short Name is provided No Data Center Role No Data Center URL is provided The Data Center URL provided is broken The Data Center URL provided is incorrect/ unrelated to the data center The URL Content Type does not match the enumeration value "DataCenterURL" The URL Type provided does not match the keyword value "HOME PAGE" The Data Center Short Name and/or Long Name does not align with the KMS The Short Name and/or Long Name does not exist in the KMS The Short Name and/or Long Name is placed in the incorrect position of the hierarchy (e.g. DOC/NOAA/OOE should not be provided in the Long Name field, because it is categorized as a Short Name in the KMS) There is an invalid Short Name/ Long Name relationship (e.g. Short Name: DOC/NOAA/OOE, Long Name: Energy Team, U.S. Geological Survey, U.S. Department of the Interior, is not a valid combination in the KMS) The UUID provided is incorrect for the Data Center The Data Center provided is incorrect for the data set The Data Center Role provided does not align with the UMM-Common enumeration values (DISTRIBUTOR, ORIGINATOR, ARCHIVER, PROCESSOR) The Contact Information provided is incorrect
	This element is categorized as medium priority when: The Data Center Related URL 'Description' element is left blank. It is highly recommended that a description be provided for each URL. The Data Center URL provided in the metadata redirects - it is recommended that the most current link always be provided A recommendation is made to change a valid Data Center keyword for purposes of consistency with other similar metadata records No Data Center Long Name is provided, when a long name exists in the KMS The information provided in the Data Center elements is better suited for the DataCenter/ContactGroup or DataCenter/ContactPerson metadata elements
	This element is categorized as low priority when: The Data Center Related URL is provided via http when https is available
	The element is provided, and follows all applicable criteria specified in the best practices section above.
