capella-sysmlv2-bridge

capella-sysmlv2-bridge provides model transformation and interoperability mechanisms between Capella/Arcadia models and SysML v2 environments.

The project aims to enable smooth data exchange and semantic alignment between the Arcadia ecosystem and next-generation SysML v2–based MBSE toolchains.

🎯 Objectives, Scope and Positioning

capella-sysmlv2-bridge is designed to support migration paths from Capella/Arcadia to SysML v2 environments while enabling practical interoperability between the two ecosystems.

⚠️ Project status: This project is currently under active development at Proof of Concept (PoC) level. Its intent is to mature through experimentation and, in the future, to contribute relevant capabilities back to the Capella project.

The project aims to:

• enable interoperability between Capella models and SysML v2 models
• support transformation workflows from Arcadia/Capella toward SysML v2
• preserve semantic intent across modeling environments
• facilitate migration experiments with controlled risk
• help organizations progressively introduce SysML v2 into existing MBSE toolchains
• remain extensible to accommodate different transformation strategies

This project complements arcadia-sysmlv2-lib:

• arcadia-sysmlv2-lib provides the SysML v2 semantic foundation aligned with Arcadia
• capella-sysmlv2-bridge enables transformation and migration from existing Capella models

The bridge focuses on pragmatic, incremental migration scenarios rather than large-scale one-shot conversions or defining a normative standard mapping.

📁 Repository Structure

/doc

Documentation describing:

• transformation principles
• mapping assumptions
• supported scenarios
• known limitations

/transformations

Contains the implementation of model transformations between Capella and SysML v2.

Depending on the implementation, this may include:

• model-to-model transformations
• helper utilities
• mapping definitions

/examples

Provides sample models and transformation scenarios demonstrating how to use the bridge.
