>>From the first lines of the manual:

This document presents the models and languages for the design of WebML
applications. WebML assumes a step-by-step approach to the specification
of data-intensive Web sites, where each step addresses a distinct
perspective of modelling.

In short, the 'web' in WebML should be replaced with "data-intensive
web".

Also, after a brief look, I think the entire concept is very weak. Sure,
they aim at total SoC, but they start from the wrong perspective: their
framework is *focused* on data-driven web sites. Their focus is mostly
in moving the 'entity-relationship' model to the web and provide a
simple way to map the two.

I honestly didn't see anything we can borrow from their effort since
it's too specific for us.

NOTE: from what I saw, it would be pretty straightforward to implement a
WebML framework on top of Cocoon.

Sounds like big time vaporware to me: where is the meat?

what does this have to do with the title?

Ok brainstorming, but let's try to keep at least focused.
