Projectgroup: JT

The JT Application Benchmark is a project of the prostep ivip Association (PSI) and the German Association of the Automotive Industry (VDA). The goal of the benchmark is to evaluate and enhance the interoperability between currently available JT applications in a fair and objective way.


JT has become a widely used format for product visualization during the product development process. The ProSTEP iViP Association and the German Association of the Automotive Industry (VDA) have launched three JT-related projects in succession, which are being coordinated with each other: the ProSTEP iViP / VDA JT Workflow Forum, the ProSTEP iViP / VDA JT Application Benchmark and the ProSTEP iViP / VDA JT Implementor Forum. In August 2010, the ProSTEP iViP Association submitted the latest JT specification (version 9.5) to the ISO for standardization. JT 9.5 was published by ISO as ISO 14306:2012 in December, 2012.

As the latest in a row of five benchmarks, the JT Application Benchmark was carried out in 2014 to achieve an independent evaluation of the progress being made with regard to the development of JT check tools. The object of testing was ISO 14306:2012 (JT 9.5). Additionally, the interoperability between JT and the STEP AP242 Business Object (BO) Model XML schema (publication as ISO Standard ISO 10303-242:2014) was also part of the benchmark. Thus, this 5th benchmark covers results far beyond state-of-the-art technology.

The benchmark was managed by the JT Workflow Forum and JT Implementor Forum. Because the benchmark is an independent activity, it was financed directly by the two organizations, the ProSTEP iViP Association and the VDA, and not by the participating companies whose products were tested. It is a neutral comparison of trendsetting JT applications with regard to the selected test criteria. Therefore, the results of the benchmark cannot only be used to evaluate the application of JT in PLM environments, but also for improvement of the interoperability of the applications.

As such applications are undergoing a permanent development; the benchmark can only give a snapshot of the functions and qualities of the applications.
