DOI Authority

• Field Definition:  System that provides an infrastructure for the registration and persistent reference of a Digital Object Identifier. The DOI name can be entered into a DOI Authority system to view the associated URL for the product.

              Example:
              http://dx.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.

              Values:
              (prefix)/(suffix)
              Prefix – 10.(number) where (number) identifies registrant agent. 5067 has been assigned for NASA ESDIS.
              Suffix – uniquely identifies the data item and its format is assigned and managed by the registrant agent.

              Example:
             10.5067/MEaSUREs/GFSAD/GFSAD1KCM.001
 

Entity ID

• Field Definition:  The naming convention of each file is based on the Local Granule ID. The Entity ID may match the Local Granule ID for some data sets.

              Format:
              Grid Format: PPPPPPPP_YYYY_LatLon_VVV_YYYYDDDHHMMSS.tif
              Global Format: PPPPPPPP.YYYY.VVV.YYYYDDDHHMMSS.tif
              PPPPPPPP= Product Short Name (Number of characters may vary by data set)
              YYYY = Nominal Acquisition Year
              LatLon = 10 x 10 degree grid
              VVV = Version Number
              YYYYDDDHHMMSS = Julian Date of Production
              tif = Data Format

             Example:
             Grid Example: GFSAD30AFCE_2015_S20E10_001_2017261090100.tif
