Webel IT Australia has tracked every inch of the development of the new SysMLv2 for next-generation Model-Based Systems Engineering (MBSE).
SysMLv2 is a major evolution of language, with some new terminology, some new modelling elements, some new notations, a Web Services API, and a powerful new textual representation modelling code. However, there are meta-principles for modelling and organising projects that go way beyond a specific language specification, and principles that go beyond tools. THAT is what we do best, the "art and science" of graphical engineering and systems thinking!
Some key features of SysMLv2 for next generation MBSE include:
- Based on the new KerML specification instead of UML.
- Has a new textural representation modelling code, a major innovation that is already making SysML more accessible and popular for MBSE.
- Has a new vendor-independent Web Services API for teamwork and model queries (SysMLv2 as a new very powerful cloud database technology).
- Better integration of Requirements with the wider SysML model, and improved propagation of quantitative Requirements across the model.
- Improved integration of state and action behaviours with the wider model.
- New mathematical calculations system (building on the previous powerful and popular SysMLv1 Parametrics technology).
- Optimal support for simulation capabilities built-in from the get-go!
- New more consistent element naming pattern.
- Improved Part definition system (replaces the Block) with support for progressive Part usage "on-the-fly" redefinitions for more powerful systems structure modelling and systems configuration and modes modelling.
- Easier handling of property redefinitions and new notations for more powerful and flexible systems hierarchies.
- Reified relationships with improved semantics.
- Improved handling of object/instance-like items and flows for signals, data, and physical quantities.
- Improved handling of values and quantities with units.
- Improved lifetime modelling.
There is also a trend towards more generative diagramming, and of course, very active work on leveraging Natural Language Processing to create SysMLv2 models and diagrams.
Some good starting points:
- Course: Model-Based Systems Engineering with OMG Systems Modeling Language® (v2) and the Cameo Systems Modeler (CATIA Magic™) tools for SysMLv2
- Topic outline for Full SysML Workshop (5-Day) course version: 'Model-Based Systems Engineering with the OMG's Systems Modeling Language v2 (SysML®) and the Cameo (CATIA Magic™) tools for SysMLv2'
- SysMLv2: EXTERNAL references, resources, presentations
- Webel's SysMLv2 wishlist and analysis
- Dr Darren's thoughts on whether your organisation should already adopt SysMLv2 as your Model-Based Systems Engineering language and the Cameo Systems Modeler v2026x SysMLv2 Plugin and SysMLv2 Evaluation Plugin (as of Mar 2026)
