List of Projects

Eclipse OCL provides libraries and tools for the Object Constraint Language (OCL) OMG standard using EMF-based models.

The Eclipse QVT Operational component is an implementation of the Operational Mappings Language defined by Meta Object Facility™ (MOF™) 2.0 Query/View/Transformation™ (QVT™). In long term, it aims to provide a complete implementation of the operational part of the standard.

Operational QVT project provides a powerful Eclipse IDE:

• feature-rich editor (syntax highlighting, hovers, hyperlinks, code completion, templates, outlines, markers, etc.)
• debugger (conditional breakpoints, variables view, expressions view, watches)
• metamodel browser, trace view
• project builders, launch configurations
• deployment facilities and Ant support
• Java API for executing QVT transformations programmatically, support for the standalone execution of transformations
• support of Java Black-Box units and libraries
• seamless integration with JDT supporting co-development of QVTo and Java in single workspace

Additional tooling QVTO Code Coverage provides:

• annotate the Operational QVT Editor to highlight covered and non-covered parts of transformation
• JUnit launch configuration to integrate with the JUnit test framework

UML2 is an EMF-based implementation of the UMLTM 2.x metamodel for the Eclipse platform.

Eclipse Trace Compass is an open source application for viewing and analyzing any type of logs or

The Eclipse EMF Client Platform is a framework for building EMF-based client applicatio

ATL (ATL Transformation Language) is a model transformation language and toolkit.

Eclipse EMF Diff/Merge is a diff/merge tool for models. Its main purpose is to help build higher-level tools that need to merge models based on consistency rules. GUI components are also provided.

Visual languages are popular for visualizing concepts and systems. However, just being graphical in nature does not automatically make a diagram easy to understand. Its usefulness much rather depends on the placement of its elements, that is: on its layout. Getting the layout right is labour intensive and time consuming and can be made a lot easier by making algorithms do the work. The Eclipse Layout Kernel (ELK) provides such layout algorithms, as well as an infrastructure to connect them to diagram editors.

Eclipse LSP4J is a Java implementation of VSCode's language server protocol intended to be consumed by tools and language servers implemented in Java.
