What is SysML2?
SysML2 (Systems Modeling Language version 2) is the next-generation modeling language designed by the OMG® to improve the precision, expressiveness, and usability of systems modeling. It builds on the concepts of SysML1.x, offering a streamlined metamodel and a unified textual and graphical syntax that supports complex system design across domains. SysML2 addresses many limitations of the previous version by introducing formally-defined semantics, better support for model-based systems engineering (MBSE), and increased consistency across modeling constructs. Its core strength lies in enabling engineers to define, analyze, and verify systems through an integrated, formal modeling approach.
With its emphasis on reusability, scalability, and machine-readable syntax, SysML2 is engineered to support modern systems engineering workflows, from concept through validation. It enhances traceability, integrates seamlessly with digital engineering tool-chains, and supports executable modeling to drive simulation and analysis. As organizations move toward full lifecycle digital models, SysML2 plays a critical role in aligning design intent, system architecture, and technical analysis within a coherent modeling framework. Whether applied to aerospace, automotive, defense, or complex product design, SysML2 is quickly becoming the essential language for robust, model-based system development.
What is KerML?
KerML (Kernel Modeling Language) is the foundational metamodel that underpins SysML2. Developed by the Object Management Group (OMG®), KerML provides the core semantics and structural rules upon which SysML2 is built. It defines the universal concepts of modeling such as types, features, relationships, and behaviors that enable consistent and precise system representations across domains. As the architectural backbone of SysML2, KerML enables high fidelity in model definition, validation, and interpretation.
Trechoro is engineered to work natively with KerML, offering a modeling-first environment that fully leverages this powerful foundation. By directly supporting KerML constructs, Trechoro allows systems engineers to create models that are semantically rich, standards-compliant, and highly reusable. This integration not only ensures alignment with the SysML2 specification but also optimizes performance and clarity, especially when managing large, inheritance-heavy models.
Whether you're building architectural frameworks or detailed behavioral diagrams, Trechoro’s KerML-native engine helps you model with precision and confidence.
