Design data transformations visually in Enterprise Architect using the OMG QVT standard, and let this tool generate ready-to-run C# code that carries out the transformation for you — no hand-written mapping code required.

The Enterprise Architect plugin (installer .msi) is built automatically on every push to master.
Open the most recent successful run and download the QVT-CodeGenerator-Plugin-Setup_* artifact from its Artifacts section (you need to be signed in to GitHub to download workflow artifacts).

A guided walkthrough is available in the slides.
The generator is a small pipeline of C# components:
- EA transformation importer reads the graphical QVT relations from an Enterprise Architect project into an in-memory QVT Relations model.
- Transformation Code generator turns that in-memory model into the generated C# "Data Transformator" that performs the actual data transformation.
- QVT textual concrete syntax generator can additionally render the same relations as textual QVT syntax.
- EA code generator packages the generated transformer back into the Enterprise Architect plugin.
The codebase is split into several independently versioned components (see .gitmodules), most notably:
| Component | Role |
|---|---|
LL.MDE.Components.Qvt.CodeGenerator |
Core QVT-relations-to-C# code generator |
LL.MDE.Components.Qvt.Metamodel / ...Metamodel.Generator |
QVT (EMOF-based) metamodel and its NMF-based generator |
LL.MDE.Components.Qvt.EnArImport / ...EnArIntegration / ...EnArInterface |
Enterprise Architect model import and integration |
LL.MDE.Components.Qvt.TextConcreteSyntaxGen |
Textual QVT concrete syntax generator |
MDD4All.QvtCodeGenerator.Apps.EaPlugin |
The Enterprise Architect plugin (and its installer) built from the components above |
Each component lives in its own repository and is included here as a git submodule under src/<ComponentName>.
