International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper presents the description of a new XML-based data display language called Data Display Markup Language (DDML) that can be used as an interlingua for different data display configuration formats. Translation of data display configuration between various vendor- formats can be accomplished by translating in and out of DDML. The DDML can also be used as a vendor-neutral format for archiving and retrieving display configurations in a test and evaluation (T&E) configuration repository.
