Its metamodel is at the core of any modeling language, the framework defining how individual modeling elements relate. One of the most notable new features is the strong emphasis on textual modeling that complements the graphical approach. However, it had certain limitations, chief among them were sometimes ambiguous semantics, incomplete textual support and limited interoperability with the wide ecosystem of engineering tools. The lesson then delves into the design and architecture of SysML v2, highlighting its new metamodel, graphical and textual syntax, and standardized API. It fosters a seamless integration and data exchange between distinct tools and systems, which is essential for implementing a solid and continuous Digital Thread approach.
Regarding interoperability, SysML v1’s partial mapping to UML caused friction with engineering tools not aligned with UML’s semantics. This has often forced engineers to rely on custom solutions or additional scripting, creating communication gaps between engineering teams. The absence of robust textual constructs sometimes meant that intricate rules, constraints or algorithmic logic ended up outside the SysML model. It addresses many of SysML v1’s shortcomings by significantly improving modeling capabilities, precision and interoperability.
