Element Description
The Data Center/ Contact Group metadata element is used to provide contact information for a group associated with the dataset. For example, these elements could be used to provide contact information for a research group within a data center responsible for generating a dataset.
Note that the Contact Group metadata element being described on this wiki page is nested under the Data Center element. Contact Group information can also be provided separate from the Data Center element (i.e. for a group unaffiliated with a data center) - see the Contact Group 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 is provided on a separate wiki page. This wiki page describes details for option 3 (Data Center/Contact Group).
Best Practices
Each Contact Group listed in the metadata must be affiliated with a Role. Providing a Role for the Contact Group is required and must be selected from a controlled vocabulary list. There are seven options for Role:
- DATA CENTER CONTACT: a group affiliated with a data center. This will should be the same data center listed in the required 'Data Center' element.
- TECHNICAL CONTACT: a group with technical (expert) knowledge about the data product.
- SCIENCE CONTACT: a group with technical (expert) knowledge about the science principles involved in deriving the data product.
- INVESTIGATOR: a group 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 group responsible for creating and/or maintaining the collection level and/or granule level metadata record(s) associated with the data product.
- USER SERVICES: the user services office at the data center responsible for archiving, distributing, originating or processing the data.
- SCIENCE SOFTWARE DEVELOPMENT: a group with knowledge of software(s) specifically developed for the data product.
The same contact group may be responsible for multiple roles. In this case, multiple roles may be assigned to the same contact group.
Other Contact Group metadata fields include:
Non Data Center Affiliation: The Contact Group metadata elements are sub-fields of the Data Center metadata element. Sometimes the Contact Group listed is not affiliated with the Data Center. This field can be used to specify the name of a larger organization the Group is affiliated with if it differs from the Data Center. Providing a Non Data Center Affiliation is optional, however, it is 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 Group is not affiliated with a particular Data Center, the contact information can be provided in the Contact Group metadata elements instead (these are not nested under a Data Center).
Group Name: The name of the group. Providing a group name is required.
Contact Information: Any relevant contact information for the group. 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).
