Specifies methods and messages to efficiently translate sequences of text and other types of data into and out of indexed values and look-up tables for effective transmission.

This SAE Standard defines methods and messages to efficiently translate sequences of text and other types of data into and out of indexed values and look-up tables for effective transmission.This document defines:aMethods and Data Elements for handling indexes and strings in ATIS applications and message setsbMessage Sets to support the delivery and translations of tables used in such stringscTables of Nationally standardized strings for use in ATIS message descriptionsAnd examples of each in illustrative portions.While developed for ATIS use, the methods defined in this document are useful for any textual strings in any Telematics applications found both in Intelligent Vehicles and elsewhere.
