Hi all,

Vinay and Sreedhar will give a presentation this year at ECMDA. They contributed an interesting document to the project (see attachement) and this can be an excellent opportunity to get together and have a discussion with them.

How about Thursday morning / noon, after the ModelBus demonstration on the Tool track?

Please let us know.

Thanks,

Sébastien

Hi Sebastien,

We are happy to find that there is a general agreement between our ideas
and approaches.

We would like to go through the detailed presentation on ModelBus that
you mentioned. We can have a more detailed discussion during ECMDA.

Pl do go ahead and post our document on the mddi mail thread.

Vinay and Sreedhar

Hi Vinay, Sreedhar,

Thank you for the reminder. The team did have a discussion on the
document and I apologize for not
replying sooner.

The document is in line, in general, with our idea of a model
integration bus. Your contribution to
project would be very welcome.

Among the most interesting points, we noticed that you consider a MDD
bus as an extension of a
generic service bus. This is exactly what we aim to do. The bus we are
developing is currently
tightly coupled to web services but, on the long term, we want to sit on
top of various technologies
(WS, OSGi, other middleware), providing a loose couple between
platform-independent aspects and a
particular technology.

You also provide interesting new ideas, such as "model deltas". Passing
deltas and not complete
models as arguments is very important if we want to avoid performance
issues with XMI-based tool
chains. That raises a series of questions: How delta models may be
calculated (delta with respect to
what baseline?) and how they can be transformed as fragments?

I am wondering about the view model integration. If we consider the
context of QVT, a view can be
calculated and maintained thanks to a source meta-model, a target
meta-model and a transformation.
What may be missing is to talk about the transformation definition,
which permits to have a complete
specification of a view. That may need further discussion, though.

We also defined tool categories. We have a bigger number of these but I
think this is not an issue here.

I guess we need to figure out a way to collaborate now. How can we
proceed to move on? Would you be
interested in a detailed presentation on ModelBus? Do you want to show
us a particular implementation?

I noticed that you guys are giving a talk at ECMDA. That can be an
excellent opportunity to have a
longer discussion. What do you think about it?

Also, are you okay with posting your document and following this mail
thread on the mddi mailing
list (https://dev.eclipse.org/mailman/listinfo/mddi-dev). External
people have additional good insight.

Thanks,

Sébastien
