SysML v2 systems modeling guidance for creating valid models with correct syntax, proper type hierarchies, and validation workflows. Use when working with .sysml files, systems modeling, architecture documentation, SysON, or Eclipse SysML tools. Provides syntax reference, common patterns, error troubleshooting, and best practices from OMG specifications.
Authoritative guidance for creating valid SysML v2 models with correct syntax, proper type hierarchies, and integration with validation tools.
SysML v2 is a textual modeling language with formal syntax. Always validate models with the command-line validator before importing into SysON or committing to version control. The language is defined by OMG specifications, implemented by Eclipse tooling, and must follow strict KerML (Kernel Modeling Language) metamodel rules.

CRITICAL: Always validate before committing or importing to SysON
