Keys for obtaining US Driver's license data

Standard for US Driver's Licenses defines 9 different barcode standards (AAMVA versions) with over 80 different fields encoded inside a barcode. Some fields exist on all barcode standards, other exist only on some. To standardize the API, we have structured the fields in the following sections:

1. Determining AAMVA version
2. Keys existing on all barcode versions
   • Mandatory values
     • Personal data
     • License data
   • Optional values
