Hi,
Please note that the actual file format is not mandated by EMF. XML/XMI is just
one of many possibilities to persist EMF models. With XText you can store
EObjects even in domain (UI) specific syntax.

Hi Sabri,
I think that every application developer (Java, C++, C# etc.) can
understand the XML format, but, it isn't the case for EMF. So if we want to
promote the a universal declarative UI, it must be XML format. The EMF is
too complex for a application developer.

Hi Kaiping,
Thank you for your exposing your experience. That's an interesting point
you have just raised. You pointed that declarative UI is finally the most
important feature for building UI. That means that for the final User who
creates the UI, whatever the declaration is in XML or EMF (Actually even if
it is in EMF the user does see the difference if he uses an editor), the
most important is that is declarative and dynamic (can be re-deployed
without compilation).
However, when the developer wants more complex integration of the
declarative UI, such as detecting the lost of focus, putting listener (as
adapter) or even connecting back-end objects by transformation (aggregate
objects, fields, etc.) the model approach makes sense.
Sabri.

Hi,
Here, I want to introduce our experiences concerning the XML UI
description:
1. Why XML UI?
My company (CCR) is one of most important reinsurance
company in the world. Our application is a specific enterprise ERP
application, which manages the contracts, the claims and the
accountings
with different kinds of insurance companies. Precisely, It has
already more
than 1500 UI forms. The UI change is our frequent activity in
software
development and the time to market is critical. The UI development in
Java
presents a lot of problems:
- High technical knowledge in UI programming for all UI
developers,
there is no separation between Component developer and Domain
developer.
- UI quality depends on Java developer skill level
- Impossible to control UI Theme and to enforce UI Guidelines
- UI Ergonomic is always ignored by Java developer
XML UI is very important for us because we want a declarative UI
description instead of a programming UI description. We think also
that the
UI description has to be independent of computer programming
language.
We look for a standard XML UI solution since long time ago. But
unfortunately, we had to develop and maintain our own XML UI solution
since
xx years ago.
2. About on XWT
We have followed closely the progress of XWT since beginning. All
features
provided seems very powerful. It is what we wait for since long time.
On waiting for e4
