Sysml v2 Diagram Support

[ericjameszimmerman]

Proposal

Mermaid.js is widely used for generating text-based diagrams, making complex visualizations more accessible to developers and engineers. As Model-Based Systems Engineering (MBSE) adoption increases, supporting SysML v2 would enhance Mermaid.js’s utility in systems engineering, expanding its reach beyond software development. SysML v2 introduces improved semantics, better model interoperability, and a structured API for data exchange, aligning with the need for more precise and scalable system representations. By integrating SysML v2, Mermaid.js could facilitate clearer communication between software and systems engineering teams, improve compatibility with industry-standard MBSE tools, and attract a broader user base in aerospace, automotive, and industrial sectors. Adding this capability would strengthen Mermaid.js’s position as a versatile diagramming tool while addressing the growing demand for lightweight, standardized, and accessible system modeling solutions.
