SysML v2 is the next generation Systems Modeling Language for modeling complex systems that significantly enhances precision, expressiveness, usability, interoperability, and extensibility over SysML v1. SysML v2 is in its finalization phase at the Object Management Group (OMG). It includes three standard specifications: KerML 1.0, SysML 2.0, and Systems Modeling API and Services 1.0 (aka SysML v2 API). The SysML v2 language (KerML 1.0 and SysML 2.0) provides a new graph-based meta-model that is not constrained by UML. SysML v2 also includes a graphical and textual notation which represent the same underlying model. The SysML v2 API enables standard CRUD operations to be performed on SysML v2 models that are managed in a repository. This provides the capability to integrate SysML v2 models with other engineering models and enterprise data in a digital thread.

At our inaugural Digital Thread Conference 2024, Sandy Friedenthal and Manas Bajaj did a joint presentation and demo of SysML v2 with a special focus on digital threads. This presentation is in two parts, as described below. 

Part 1 : SysML v2 – The Next Generation Systems Modeling Language enabling Digital Threads 

• Presenter: Sandy Friedenthal | SAF Consulting, Co-Chair of SysML v2 Submission Team and Systems Modeling Community
• Description: Part 1 provides an overview of the SysML v2 language with a special focus on integration and digital threads. The presentation covers the SysML v2 language architecture, usage patterns, textual and graphical notations, improvements compared SysML v1, and goals of the Systems Modeling API and Services (SysML v2 API).

Part 2 : Digital Threads with SysML v2 and Syndeia

• Presenter: Dr. Manas Bajaj | Co-Chair, Systems Modeling API and Services FTF (OMG), Chair SMC API and Services WG (OMG), and Chief Systems Officer (Intercax).
• Description: Part 2 demonstrates live digital threads for a Spacecraft example using SysML v2 API and the Syndeia digital thread platform. The presentation showcases the use of Syndeia to generate, query, and visualize live digital threads connecting SysML v2 models with hardware (PLM), software (ALM), verification (Test Management), and other engineering models of complex cyber-physical systems.

Background

Intercax has been at the forefront of SysML v2, and part of the core leadership of SysML v2 Submission Team (SST) at the Object Management Group (OMG) since the beginning.

• Dr. Manas Bajaj (Chief Systems Officer, Intercax) has led the Systems Modeling API and Services 1.0 specification from the RFP to the finalization stages. Intercax hosts and maintains the SysML v2 API pilot implementation repositories for the SST, enabling end users to test drive the SysML v2 API.
• Syndeia was the first commercial tool to integrate with the SysML v2 API – Syndeia 3.4 release in 2021 included support for SysML v2 API (2021-03 release). Since then, subsequent Syndeia releases have brought new and improved capabilities with SysML v2. The Part 2 demonstration shows Syndeia 3.6 in action with SysML v2 API.
