SysML Language Server — SysML v2 Editor Support
What is SysML v2?
SysML v2 is the OMG standard for modeling complex systems: requirements, structure, behavior, and parametrics in a single, textual language (KerML / SysML). It enables a single source of truth for system definition and supports model-based systems engineering (MBSE) with machine-readable, analyzable models.
What is the SysML Language Server?
The SysML Language Server brings first-class editor support for SysML v2: syntax highlighting, completion, go-to-definition, diagnostics, and validation inside VS Code. It helps teams work with SysML and KerML files as structured artifacts instead of plain text, and fits into Git-native, model-based workflows.
