Element Description
The Data Center/ Contact Person metadata element is used to provide contact information for an individual associated with the dataset.
Note that the Contact Person metadata element being described on this wiki page is nested under the Data Center element. Contact Person information can also be provided separate from the Data Center element (i.e. for a person unaffiliated with a data center)—see the Contact Person wiki page for details.
There are 5 options for providing contact information in the UMM:
- Data Center
- Data Center/ Contact Person
- Data Center/Contact Group
- Contact Person
- Contact Group
Details for each of these options are provided on a separate wiki page. This wiki page describes details for option 2 (Data Center/Contact Person).
Best Practices
Each Contact Person listed in the metadata must be affiliated with a Role. Providing a Role for the Contact Person is required and must be selected from a controlled vocabulary list. There are seven options for Role:
- DATA CENTER CONTACT: an individual affiliated with a data center. This should be the same data center listed in the required 'Data Center' element.
- TECHNICAL CONTACT: an individual with technical (expert) knowledge about the data product.
- SCIENCE CONTACT: an individual with technical (expert) knowledge about the science principals involved in deriving the data product.
- INVESTIGATOR: a person involved in the creation of the data product. For instance, this might be the principal investigator (PI) or co-PI of the project responsible for creating the data product.
- METADATA AUTHOR: a person responsible for creating and/or maintaining the collection level and/or granule level metadata record(s) associated with the data product.
- USER SERVICES: an individual representative of the user services office at the data center responsible for archiving, distributing, originating or processing the data.
- SCIENCE SOFTWARE DEVELOPMENT: a person with knowledge of software(s) specifically developed for the data product.
The same contact person may be responsible for multiple roles. In this case, multiple roles may be assigned to the same contact person.
Other Contact Person metadata fields include:
Non Data Center Affiliation: The Contact Person metadata elements described on this wiki page are sub-fields of the Data Center metadata element. Sometimes the Contact Person listed is not affiliated with the Data Center. This field can be used to specify the name of the organization the Contact Person is affiliated with if it differs from the Data Center. Providing a Non Data Center Affiliation is optional, however, is it recommended that this information be provided when the affiliation of the Contact Person differs from the Data Center they are listed under. Alternatively, if the individual is not affiliated with a particular Data Center, their contact information can be provided in the Contact Person metadata elements instead (these are not nested under a Data Center).
First Name: The first name of the contact person. Providing a first name is optional.
Middle Name: The middle name of the contact person. Providing a middle name is optional.
Last Name: The last name of the contact person. Providing a last name is required.
Contact Information: Any relevant contact information for the contact person. 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).
