# SysML v2 Systems Modeling

Authoritative guidance for creating valid SysML v2 models with correct
syntax, proper type hierarchies, and integration with validation
tools.

## Core Principle

**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.
