SOUTHFIELD, MI-TheDimensional Mark Up Language (DML), has been updated, incorporating changes and input from industry, to enhance the robustness of the specification, says the Automotive Industry Action Group (AIAG).

Developed in partnership with the National Institute of Standards and Technology (NIST), DML is a common global language specification for metrology, which allows for the seamless interface of computer-aided design (CAD) software, inspection program planning and execution, and CMM and inspection analysis tools.

The DML was updated to meet current industry needs. This revision provides an explanation of the changes from DML Version 2.1 to Version 3.0. Accompanying the updated document is revised DML schema in XML format.

Also included is a copy of the original DML publication, which describes the basic fundamentals of a well-formatted data set and provides definitions for the elements that constitute the standard. It details elements and attributes that comprise DML and provides the basic rules necessary to follow when developing applications that either write or read in DML.

The goal of this standard is to reduce the product development cycle time and manufacturing costs by achieving interoperability of the software and hardware components used in automated metrology. By using DML for interoperable data, suppliers and OEMs stand to save millions through the elimination of redundant costs and the reduction of delivery and design-to-production times.

The Dimensional Mark Up Language (D-23), third edition, is available as an electronic document from AIAG at a price of $25 for members and $50 for nonmembers.Purchase Your Copy Online.
