Re: [modeling-pmc] Re: [emft-dev] Proposal for Texo Component

Hi Yves,
I think this is more a terminology thing, with Ui-model I mean what you are refering to so definition of master/detail, selection dialog, page flows etc. and not the technical ui implementation. So afaics we mean the same thing.

I don't know which the presentation modeling framework you are talking
about. I have prepared a project named as PMF (presentation modeling
framework). But it is NOT an UI-model like XUL, XAML. It is an abstract
modeling framework that implements the presentation patterns like data
binding, page flows, Master/Detail etc. Each technology like JSF, SWT, GWT
then can implement its generator. Please find the draft in the attached
file.

Hi Christian,
Depends on how you look at it. On the one hand the artifacts generated are editable using wtp (for example jsp editor, dali project). On the other hand the Texo project does not need to make use of any component currently present in wtp while it uses (and tightly integrates with) emf, mwe, jmerge, teneo and xpand. Also the ideas for a ui-model (the presentation modeling framework) will be used by Texo. In addition it is the idea to make it possible to extend the solution with custom templates/workflows. So as there is a definite and large modeling side to it I would say that it belongs to modeling.

Hi,

Can one also make an argument for locating this component in the Web Tools
Platform project?  It seems to me that Texo is more of a model-driven web
application development tool (and WTP is all about developing web apps)
than it is a framework for building modeling tools or even a big-M
modeling
app.

Cheers,

Sven,

Once-only code generators really do suck, so you have to wonder at their
preponderance given how relatively trivial it was to build Java merge
support. The original design and implementation of JMerge took roughly a
week of effort, as a I recall.  EMP is definitely a great basis for
building DSLs with the added benefit that they all have a common
underlying
meta model to ensure that we don't end up with just a Tower of Babel.  In
addition, we aren't suffering from the misguided belief that XML syntax is
the be-all-and-end-all of human readable notations.

In our quest toward a grand vision, I think it's best to start small and
to
build the little pieces bottom rather than carve out a grand high level
space top down.  We also have to consider our project's charter and be
sensitive to the concerns that the scope of the modeling project could
just
creep out to consume all other projects.   Many DSLs would most logically
live in other projects and we'd be best off to ensure that things evolve
in
that direction when it makes the most sense.  So for the time being, I'd
rather avoid creating more direct child projects under the modeling
project.  Having a small number of projects to group the large number of
components seems appropriate...

Hi all,

this sounds very cool. We all know that there are many general
frameworks (web, RCP, SOA, etc,) out there which would profit from
generators.
Some of them (Ruby on Rails, Grails, SEAM just to name a few) already
use code generation a lot.
Unfortunately they use wizard-style passive code generation, where you
generate once and further change the generated code manually.
So most of the time generators are just used to get users up and
running as fast as possible.
Also they come up with concise languages to descibe domain models
(internal DSLs).
Those languages are not statically typed, have to fit into the host's
syntax and have no tool support at all (EMP can do better).
IMHO there should be some more projects like Texo, which show how EMP
can be used.

As EMFT is for EMF technology I find that those projects don't fit
well there. We should create a new Project for such domain-specific
applications of EMP.
What do you think?

atb,
Sven

btw: +1

Extended EMF Community,

Martin Taal, the lead for the Teneo component, recently announced his
intent to work on the Texo component which will focus on exploiting
modeling technology for building web applications.

  http://wiki.eclipse.org/Texo

I request the community's approval to create this new component as
part of
the EMFT subproject with Martin Taal as the component lead.  Please
reply
with +1 or -1 on this thread.  Obviously I recommend you give a +1,
given
Martin's outstanding track record with Teneo and his exemplary
support for
it.  All EMF and EMFT committers are eligible to vote, so please
take a
moment to do so.
