SysML v1.6 to v2.0 Transformation Pipeline

This project implements a model-driven transformation pipeline to migrate SysML v1.6 Block Definition Diagrams (BDDs) into equivalent SysML v2.0 textual models. The pipeline is built using Eclipse-based technologies and adheres to the Model-Driven Transformation Development (MDTD) methodology.

The transformation process includes:

• Model-to-Model (MTM) transformation using QVT Operational (QVTo)
• Model-to-Text (MTT) transformation using Acceleo
• Metamodel definitions for both source (SysML v1.6) and target (SysML v2.0) representations

✅ This project was developed as part of a Master's Thesis on model-based language migration for Digital Twins.

🔧 Setup Instructions

1. Clone the repository

   git clone https://github.com/dkrgn/master-thesis.git
   cd master-thesis

2. Install Eclipse and dependencies

   • Install [Eclipse Modeling Tools](https://www.eclipse.org/downloads/packages/release/

   During the development, 2024-03 version was used for QVTo. However, perhaps, due to the version clashes, we could not install Acceleo for this particular version. Thus, we decided to downgrade Eclipse to 2023-06, which helped to resolve the problem with Acceleo. We recommend to use 2023-06 Eclipse version both for QVTo and Acceleo.

   • Install the following plugins:
     • QVTo (Query/View/Transformation Operational)
     • Acceleo (Model-to-Text generator)
     • EMF SDK (if not included)
   • Install Papyrus to configure SysML v1.6 models and respective .uml files

3. Import the projects into Eclipse

   • Go to File > Import > Existing Projects into Workspace
   • Select the master-thesis folder and import all contained projects

▶️ Usage Guide

1. Open a sample SysML v1.6 model

   • Located under v1.6tov2.0/models/ or create one using Papyrus with SysML 1.6 profile

2. Run the QVTo transformation

   • Right-click the .qvto file (e.g., v1tov2.qvto)
   • Select Run As > Run Configurations > QVT Operational Transformation
   • Create new configuration
   • Input: SysML v1.6 .uml
   • Output: Intermediate SysML v2.0-compliant XMI model (put the desired path and file name, e.g. platform:/resource/v1.6tov2.0/valid-target/valid1.xmi)

3. Run the Acceleo M2T generator

   • Right-click generate.mtl under v2totext/src/v2totext/main/
   • Select Run As > Run Configurations > Acceleo Application
   • Create new configuration
   • Input: the .xmi model
   • Output: SysML v2.0 textual model in .sysml

4. Validate output

   • Open the generated textual model and inspect structure and syntax
   • Compare key elements (Blocks, Properties, Associations, etc.) to source
