Hi
I have been using Medini-QVT which is no longer actively maintained and needs to be used within an old version of Eclipse. The documentation I found around avtd is extremely scant. Has anybody got experience with using qvtd, the extend to which it supports the QVT-Relational spec and how it compares to Medini-QVT?
Appreciate any inputs :).
There's no need to use Medini any more. Eclipse "QVT Operational" (QVTo) is a partial implementation of the Operational Mappings Language defined by the OMG standard specification (MOF) 2.0 Query/View/Transformation (s. eclipse.org). Books, tutorials and OMG specs are available. As you can read in the eclipse wiki, "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". From my point of view, it's a good idea to start with QVTo and not with QVTr. The reason is simple: it's easier to understand and you don't need the power of QVTr in the beginning (like bidirectional model transformations).
I am using the MediniQVT Engine in Eclipse Kepler. The MediniQVT plugin is built on top of the MediniQVT engine, which runs stand-alone.This plugin is not compatible with newer versions of Eclipse, but I see no reason why the engine should not run in newer versions of Eclipse. The trickiest part was to figure out how to run the engine without the plugin, because it is documented nowhere. I could give you instructions how to get it running if you are interested.
Furthermore, I also took a look at QVTd. I actually use QVTd for the generation of QVTr scripts. I am not really up to date concerning the project status, but I think QVTd is not ready to execute QVTr transformations. You might also be interested in the Fujaba TGG interpreter or Henshin TGG.
