Tool Integration & Model Lifecycle Management Working Group

Provides a forum for discussion of best practices, methods and processes that promote the development, validation and deployment of standards to advance data exchange capability of digital data created during a product development lifecycle.

Working Group Purpose & Mission


The Tool Integration and Model Lifecyle Management WG provides a forum for discussion and dissemination of best practices, methods and processes that promote the development, the validation and the deployment of standards to advance the exchange of digital data between MBSE tools and toolsets.

The TIMLM WG is focused on the integration and interoperability of tools, data, models and processes as they relate to Systems Engineering processes and methods throughout the acquisition and product development life cycles. The TIMLM maintains collaboration with PDES Inc., ISO and STEP standards organizations, the INCOSE Standards Development Department and other INCOSE Working Groups as required to support standards that improve the exchange, archival and retrieval of digital artifacts produced by our systems engineering processes.


  • To provide the systems engineering community a reliable source of information about tool data exchange standards used while executing their business processes in the product lifecycle.
  • To collaborate with data exchange standards organizations and other supporting INCOSE Working Groups to characterize systems engineering tool integration and interoperability requirements for tools and data standards for the exchange of Model Based Systems Engineering (MBSE) digital artifacts.
  • To promote the development, validation and deployment of standards that advance the interoperability, storage, archival and retrieval of digital data and artifacts produced by systems engineering processes.
  • To provide a forum for the discussion and dissemination of information regarding tool integration, data exchange processes, use cases applying standards and the data exchange accomplishments of in our engineering community

Activities and Coming Events

  1. Four PDES MBSE and LOTAR MBSE Workshops were conducted in 2022 covering NAS 9300 Part 500 documentation product development, Boeing - MIC to AP243 Mapping, Data Exchange Solutions, Modelica, FMI and SSP for LOTAR models, SysMl v2 review (Friedenthal); using AP243 (MoSSEC), example of archiving models (LOTAR). Notes and summaries available on request and on our Yammer site.
  2. The next Semi-Annual MBSE for PDES and LOTAR Workshop is being held in Phoenix, Arizona September 17-22. Virtual meetings will be available.  Stay tuned to our Yammer site for details.
  3. PDES/LOTAR/TIMLM meetings are held weekly every Wednesday from 08:30 to 10:00 AM (Central Time USA).
  4. ISO-10303-AP243 (MoSSEC) has been approved by ISO and released to the public. PDES/INCOSE/LOTAR has embraced this standard for model exchange and is updating all specifications and standards accordingly.
  5. The Model Portfolio Management Guideline has been submitted for publication as a working group and INCOSE product and is scheduled for release shortly after IS2023.
  6. MoSSEC Sessions are scheduled for the MBSE Lightening Round at IS 2023 in Honolulu, Hawaii.

IW23: International Workshop Focus

At IW 2023 we conducted all-day MoSSEC Workshop on Monday January 30. The main sessions were presentation sby four tool vendors that are implementing MoSSEC data exchange portals. In additiona several open discussions on the MoSSEC standard impact to tools and processes, interaction with other standards and potential use cases were conducted with the virtual and attendending audience.

Topics included:

  • An introduction to MoSSEC
  • Siemens Digital Systems interactive presentation and demonstration of their MoSSEC implementation
  • Interactive presentation and demonstration by Modelon Inc.
  • Presentation on APROCONE WoW by Hexagon
  • Presentation by The REUSE Company implementation using their SES Systems Engineering Suite with a MoSSEC Connector
  • Discussions and whiteboarding about MoSSEC, Ontologies, OSLC and the interconnection of other standards
  • MoSSEC Implementation Forum Planning
