The QVTc and QVTr editors should be usefully functional. The 0.10
editors from the download pages may be slightly better.
The ModelMorf examples had only a couple of errors with the 0.8
IMP-based editors. I must confess that I haven't checked them properly
with the newer Xtext-based editors. I suspect that they just need import
declarations. In 0.8, a Model Registry was required to specify the
meta-model name to location mapping. I eventually decided that this was
a language bug and introduced import, include and library declarations.
Look at the Rel2Core which is what I use mostly for exercising.
My company, Willink Transformations, is sponsoring an EngD student at
York to pursue the progressive transformation approach outlined in
http://wiki.eclipse.org/MMT/QVT_Declarative_Languages. Currently some
very simple QVTi transformations are working. This gives confidence that
the approach is good. The execution work is all Open Source and
currently on GitHub at git://github.com/arcanefoam/qvtMustus. It will
move to Eclipse in a few months.
The goal is basic QVTc execution for Kepler, basic QVTr execution for
Kepler+1, optimized execution for Kepler+2.
The code is all layered on top of the new Xtext-based, UML-aligned pivot
OCL binding, so the new direct OCL to Java code generator can be
exploited to give high quality compiled transformation code.
