September 2009 - JT Specification accepted by ISO
September 2009 - Darmstadt– Currently there is no other format more discussed than JT. Now a major step has been done: On September 18th the ISO stated officially that the JT specification has been accepted for publication as an ISO Publicly Available Specification (PAS). The ProSTEP iViP Association, in cooperation with the VDA (German Automotive Association), was significantly involved in this step.
By publishing JT as ISO PAS (ISO PAS 14306) the major precondition for a broad application of JT in the industry is fulfilled. At this point we would like to thank all other enabling companies and organisations.
The JT ISO PAS covers the already for download available JT version 8.1b, including the Parasolid XT Format necessary for the representation of the geometrically exact XT BREP within the appendix.
Right after the announcement that JT will become a standard the VDA and ProSTEP iViP launched 2 projects beginning of 2009 for forming a solid basis for the application of JT.
Within the so-called ProSTEP iViP/VDA JT Workflow Forum representatives of well-known user companies specified use cases and requirements addressing the JT format, the related translators as well as the processes. Until today, already 15 use cases are documented - ranging from Supplier Integration, to DMU, to Digital Manaufacturing. Further use cases will be defined in 2010 (e.g. long-term archiving).
Based on the results of the ProSTEP iViP/VDA JT Workflow Forum currently a ProSTEP iViP/VDA JT-Translator-Benchmark is conducted. Here, the data exchange quality of JT-Translators from Theorem, T-Systems, CT Core Technologie, and Siemens PLM in combination with CATIA V5 R19, Pro/ENGINEER Wildfire 4.0, NX 5, and MircoStation V8 XM are put to the acid test. The results of the benchmark will be published January 2010. For 2010 a successor of this ProSTEP iViP/VDA JT-Translator-Benchmark is planed.
Beside this, for assuring interoperability with regard to JT data exchange a ProSTEP iViP JT Implementor Forum is planned for 2010.
Additionally, the ProSTEP iViP Association recently published the White Paper “Applying JT” for its members in order to offer guidance for using JT in practice.
