Update of DIN Spec 91383 (JTIAP V2): 

    • Due to several requests an update of  DIN Spec 91383 in Arbeit started reasently. It will contain all enhancements which were planned for ISO 14306. Unfortunately ISO 14306 has an unpredictable delay. In addition we will expand the number user scenarios described and published by JT Workflow Forum.

    • Never change a winning team, hence the update of DIN Spec 91383 will be executed by active members of prostep ivip association supported by VDA working group PLM. I will lead this team.

    • Ideas and enhancement-proposals as well as offers to contribute to the working.group are very appreciated. Don´t hesitate to send me a mail.
    • Effective 2021-05-14 business plan for the update was approved by concortium. All preperations are done. Standardization work has started and will be finalized in the next weeks.



Implementations on DIN Spec 91383 (JTIAP V2): results of the fourth survey

  • In March 2019, the fourth worldwide survey on the current activities concerning the implementation of the JT Industrial Application Package Version 2 (DIN Spec 91383)  was carried out. Here are the results in summary:

  • CAD ISV´s:

    • Autotdesk will deploy JTIAP V2 fully for their authoring-tools and integrate it in their ATF-translator
    • DS will support ISO 14306 ed1 as well as  JTIAP V2 by partner solutions
    • PTC uses Siemens JT toolkit for their JT compatible products 
    • Siemens products that create and utilize JT are compatible with JTIAP V2


    • Eleven out of fifteen system-integrators have a complete solution available today
    • Two have parts of the solution available and are engaged in further development
    • Two are waiting for customer request

  • To sum up: 
  • We have reached in a short periode of time an outstandig maturity
  • On the user side we have more than 250 Mio JT files in the databases done by more than 100.000 Users 
  • We have the direct support from nearly all ISV´s
  • We have integration solutions from nearly all relevant systemintegrators
  • So the deployment project of JTIAP V2 and DIN Spec 91383 has completed it´s mission and can be closed. All further activities will be done by prostep ivip JT Workflow and Implementor Forum

 News Januar 2019

  • DIN SPEC 91383 is now formally approved and publishedl
  • The continuous development of JT standardisation has reached the next milestone. JT Industrial Application Package V2 has been updated and enhanced (e.g. taking ISO14306-2017 into account). So we have generated a formal and public available document with the crediablity of the German Standarisation Organisation DIN. DIN Spec 91383 - 2018 can now be used and has the potential to be the starting description for the next version of ISO 14306.

  • The document combine different specifications and standards to a comprehensive industrial approved concept:
    • The definition of precise geometry is based on ISO 14306-2017, with  XT-B-Rep as mandatory mathematical representation 
    • The XML-structure- and kinematic-definition is based on ISO 10303  (STEP AP 242 -XML)
    • The extensions of JT specification and a mor powerful data-compression is based on  prostep ivip recommendation PSI 14-1:2016 (JTIAP V2)
    • The use-case-descriptions of JT Workflow-Forum are linked to  prostep ivip recommendation PSI 14-2:2015
  • The specification  is available and can be downloaded under  Download DIN Spec 91383
