QVT Operational

Complex model transformations written in general-purpose languages like Java are often huge and hard to maintain. The OMG QVT (Query/View/Transformation) open standard defines a model-oriented transformation language.

QVT Operational component is an implementation of the Operational Mappings Language defined by Meta Object Facility™ (MOF™) 2.0 Query/View/Transformation™ (QVT™).

Leveraging Eclipse OCL, the Operational QVT project aims to be fully compliant with the QVT standard providing 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
