The ACD provides a single list of codes that all jurisdictions can understand and removes the need for a jurisdiction to map their laws and rules to the laws and rules of every other jurisdiction.
The ACD Manual is available at: http://www.aamva.org/ACD/

In JSON alpha-numeric text is conveyed in elements with a "string" data type, which supports:
; " ~ ! etc.). Note on AAMVA systems, the allowable characters may be restricted by the Printable Character rule.
In JSON binary data is held in fields with a type of string. Binary data can be Base64 encoded, then the encoded data can be held in a sting field. Base64 can support any data because it encodes the data as regular keyboard characters (i.e. a bad date like "1987-06-aa" is encoded to "MTk4Ny0wNi1hYQ==" in base64). The most common usage of base64 is for data like digitized photos.
Enumerated code lists are exchanged in elements with a "string" data type. See the data dictionary for the list of valid values.
In REST dates are conveyed in elements with a "string" data type. In AAMVA applications these dates use a CCYY-MM-DD form, i.e. 2001-12-31. Note in AAMVA systems, Date is used in place of DateTime because the time is not recorded for the business fields being exchanged.
In REST dates-time stamps are conveyed in elements with a "string" data type. In AAMVA applications these time stamps have a date in the CCYY-MM-DD form and a time in the HH:MM:SS form. Together the date and time are held as 2002-05-30T09:00:00Z
Individual elements may optionally specify they will include a time zone, to indicate the offset from the UTC time, i.e. 2001-12-31T13:30:00+06:00.
Unified Network Interface—AAMVA's interface software for a site’s application system to exchange messages with other parties using the AMIE protocol. E.g., when sending an interactive messages UNI can format the data into AMIE form, log the message and deliver the message over the AAMVAnet telecommunications network (through NCS). Information about UNI and its capabilities are available on https://www.aamva.org/technology/uni.
