Date Updated

• Field Definition:  Date the data were last updated in the database

 

DOI Authority

• Field Definition:  The Digital Object Identifier (DOI) Authority provides the infrastructure for the registration and services for a persistent reference. The DOI authority is used along with the DOI Name to view the associated URL for the product.

          Example:

               http://dx.doi.org or https://doi.org

 

DOI Name

• Field Definition:  Digital Object Identifier is used to uniquely and permanently identify a dataset. The DOI name is more stable than a URL and is used as a permanent reference for the product. The DOI name can be entered into a DOI Authority system to view the associated URL for the product.

          Example:

              10.5067/MEaSUREs/GFCC/GFCC30FCC.001
