Incremental/Bi Directional Model Transformation [message #63444]

Hi,

I am looking for a framework that supports both incremental and
bi-directional transformation of models (I prefer EMF based). Does ATL
support this, or should I be looking at some QVT impl ?

I came across MTF which looked promising, however it is not open source.
Does anyone know what technology is behind it ?

Hi Ali,

Operational QVT supports only uni-directional transformations. Current
implementation doesn't support incremental either however it is planned
to be implemented.

Sergey

Hi,

Currently, I would say that incrementality is planned to be implemented
in ATL.

About QVT, the Relations language support bi-directional transformations
(in its specs). I am currently working on the QVT Relations component
which *will* support bi-directionality and incrementality (as long as it
does not conflict with your rules of course ;)). But the tool is not
ready yet.

The "Bridge between Domain Specific Languages (DSLs) and UML profiles"
AMW use case shows how model weaving and model transformation can be
combined to create a bidirectional Domain-Specific Transformation
Language (DSTL). This DSTL is only able to transform profiled models
into models conforming to a metamodel, and vice versa (i.e., its domain
is the metamodel-profile mapping). The use case is available at:
http://www.eclipse.org/gmt/amw/usecases/umlprofiles/

The same scheme may be used to create other bidirectional DSTLs for
other domains. Note that the larger the domain, the more difficult this
is likely to be. However, this mechanism provides means to adapt the
semantics of "bidirectionality" to a specific domain, which the General
Purpose Transformation Languages (GPTLs) do not support.
