MMT/QVT Declarative (QVTd)

Revision as of 12:57, 22 November 2009 by (Talk | contribs) (Currently working on)


The QVT Declarative (QVTd) component aims to provide a complete Eclipse based IDE for the Core (QVTc) and Relations (QVTr) Languages defined by the OMG QVT Relations (QVTR) language. This goal includes all development components necessary for development of QVTc and QVTr programs and APIs to facilitate extension and reuse.

The QVT Operational (QVTo) component provides corresponding facilities for the Procedural Language.

QVT Declarative currently provides:

  • Editors for QVTc and QVTr
  • Parsers for QVTc and QVTr
  • Meta-models for QVTc and QVTr

(The EMOF-based implementations of the QVT models are the source of the normative models in ptc/09-11-04 for OMG QVT 1.1.)

QVT Declarative will provide

  • a dedicated perspective
  • an execution environment for QVTc and QVTo
  • an integrated debugger for QVTc and QVTo


The base working document of this component is the OMG specification ptc/07-07-07 (Meta Object Facility (MOF) 2.0 Query/View/Transformation Final Adopted Specification).

The QVTR project includes a special developpement documentation to exhibits:

  • specification deviance (and explanations)
  • specification interpretation
  • specification issues

This page is a summary of specification related developpement choices. Its main purpose is to a base of discussion with the community. For any feed back on those pointsi is welcome. Please use the M2M newsgroup for the questions and the Bugzilla for issues.

Questions and discussions about Relational QVT usage

Questions and discussions about the usage of Relational QVT should take place on the eclipse.modeling.m2m Eclipse newsgroup for the M2M project (more details about this newsgroup there), of which QVTR is a component. Please, remember to prefix the subject of your Relational QVT-related posts with [QVTR].
