  • Technology standards support and optimize the exchange of data between organizations. Standards include data element standards, message exchange protocols, and others that can be used in private and public environments. For example, standards can be used over virtual private networks (VPNs), the Internet, and batch exchange environments.

    AAMVA uses and develops many standards for exchanging motor vehicle and driver information, grouped into the following categories.

    These types of standards...
    Provide...
    And include...
    Data Standards Data element definitions and coding instructions to promote uniformity of data elements communicated between organizations. This allows you to identify and exchange data between you and your partners and jurisdictions to assure the issuance of accurate licenses, registrations, and title.
    Message Protocols Encoding of data so that it can be transferred between organizations that use any platform, with any application. AAMVA uses and provides protocols that can be used in any exchange environment, including the Internet, AAMVAnet, GXS Information Exchange, and batch file transfer.

    AMIE

    The AAMVAnet Message Interchange Envelope (AMIE) is a protocol developed by AAMVA to enable organizations to exchange information on AAMVAnet. It is also used for batch exchange and in GXS Information Exchange, provided by AAMVA Network Services.

    To convert messages to and from AMIE format, you can use AAMVA's UNI and AMIE/ba software.

    XML

    EXtensible Markup Language (XML) is a set of rules for encoding documents electronically based on descriptive tags. XML is defined and maintained by the World Wide Web Consortium (W3C).

    AAMVA implements XML through web services and MAX, which is AAMVA's XML counterpart of AMIE. For data standards within XML, AAMVA uses the National Information Exchange Model (NIEM)
