Also from the metadata:

Process description: The following steps were performed by Esri: Extracted the file geodatabase (.gdb) feature class from the subset of World Base Map. Removed all first-level administrative subdivisions. Updated country names as needed. Ran the Erase tool using polygons from the World Base Map Hydropolys feature class to remove the areas that represent seas and large lakes that cross international borders. Added the fields COUNTRY and CONTINENT and coded them from source fields in the World Base Map Country_Boundaries feature class. Added the field ISO_CODE and coded it by combining the values of the fields ISO_CC and ISO_SUB. Added the field ADMINTYPE and coded it by removing the administrative types from the field NOTES. Added the fields LAND_TYPE and LAND_RANK and manually determined their values from the Shape_Area field. Deleted fields not needed. Dissolved on all fields to make multipart features for the fields LAND_TYPE and LAND_RANK.
