In case you didn’t see the announcement a few weeks ago, JT has been accepted as the world’s first ISO standard for 3D visualization. I thought it would be good to provide some history and context on how JT got to this point.  We started the JT Open Program 10 years ago at the request of our automotive customers. They saw value in JT for data sharing and collaboration across their organizations. Program membership grew pretty fast and soon we had a cross section of automotive, aerospace and consumer products members. The group knew JT as a defacto industry standard for 3D visualization and collaboration but we wanted to ensure JT had a future as an open standard.

JT accepted as ISO Standard

Leaders in the JT Open Program’s Management Review Board agreed that the only way to truly confirm JT as the common open solution for 3D visualization and collaboration was to get it recognized by ISO. We hatched a dream to make JT an ISO standard. Program members who worked on adoption of other ISO standards helped us get started with the process.

We went pretty far on our own, getting the JT file format specification accepted as an ISO Publically Available Specification (PAS) in 2009. Through that process we learned to be successful in standard development and acceptance you need strong allies. ProSTEP iViP joined the charge to move the PAS forward and remained to sponsor the project through international standard status.

So JT is now ISO 14306:2012 Industrial automation systems and integration — JT file format specification for 3D visualization. As Ken Versprille points out in Desktop Engineering’s article “Siemens PLM software Walks the Walk with Openness Promise”,

“Official ISO support for JT does not impact the technology or the capabilities of JT per se, but it does silence the naysayers…”

With ISO acceptance of JT we stay true to our commitment to openness and ensure our customers can truly own their data. We also continue to support other openness efforts, such as the Codex of PLM Openness (CPO). Stay tuned to our Open PLM website for updates.

Tell me what this means to you. How can JT becoming an ISO standard help your organization?
