Description:

Preliminary QVTr to QVTc to QVTu to QVTm to QVTp via QVTs to QVTi to Java compiler.

Architectural Issues:

OMG QVT is an extension of OMG OCL, and Eclipse QVTd is an extension of Eclipse OCL. The reused metamodels and Xtext grammars result in a very tight coupling between Eclipse QVTd and Eclipse OCL.

The QVTr to QVTc to QVTu to QVTm to QVTp via QVTs to QVTi transformation chain uses Epsilon as a bootstrap. Epsilon is a mature Eclipse project not availlable in the Simultaneous Release. Epsilon plugins are therefore hidden as internal libraries in the release. These can be eliminated once the transformation chain is rewritten using QVTr.

Security Issues:

None.

Non-Code Aspects:

The build uses Buckminster on the OCL HIPP.

Usability Details:

The Xtext-based editors provide a conventional editing experience.

The transformation chain to support compilation is nominally available, but in a very preliminary state suitable only for researchers and experimenters. In practice QVTd transformation execution is only possible for transforms manually expressed in the low level QVTi representation.

End of Life:

There are no specific end of life concerns for this release.

Standards:

OMG QVT 1.2 (http://www.omg.org/spec/QVT/1.2/)

Communities:

The QVTd newsgroup has a low level of traffic (20 messages per year).

More messages occur by mistake on other newgroups.
