About Fennec M2X ​

Fennec M2X (org.eclipse.fennec.m2x) provides clean-room, specification-compliant implementations of the OMG modeling-transformation stack — OCL, QVT Operational, QVT Relations and MOFM2T — that run as plain Java 21 libraries and as OSGi services. Every engine works without the Eclipse platform.

Use it in the Eclipse IDE ​

The OCL engine ships as an Eclipse feature that adds OCL delegate support to the generic EMF editor. Install it from the Eclipse update site, or follow the installation guide.
