[jwt-dev] Extending the JWT Editor with Extension Points?
|
Hi,
I want to make a suggestion of how to extend the JWT Modeler with vendor
specific extensions.
We talk yesterday to Florian Lautenbacher and Bernhard Bauer and discuss
the possibility that we from Imixs use the JWT Editor in future to model
Workflow Models for our "Imixs IX JEE Workflow Engine".
The general requirement for us is that we need to model a lot of
individual Informations/Attributes to each Activity inside the model.
For example our engine supports a "IX Mail Module" which needs
informations to generate a email during a transition.
So now what I want to suggest is: Why not to use the concept of Eclipse
extension points to extend the JWT Model itself?
My idea is that a vendor should not only be able to use a predefined
extension point inside the JWT Editor to add additional property pages
to an activity object. But also a vendor can describe an individual
model extensions using the same mechanism as used by eclipse to extend a
plugin.
So for example, if we form Imixs like to extend the JWT Editor with an
additional property tab to describe the informations for our "IX Mail
Module" we also add an XSD File to describe the structure of the data.
The XSD File can be very similar to the XSD Files generated with the
Eclipse Plugin IDE. In fact JWT can use the existing Eclipse XSD Editor
concept for this.
In the end the JWT Editor extends the model xml file itself with the
additional structure for an activity as described in this XSD File or
creates an additional separate Model File. The informations are provided
by a property page from vendor specific plugin. Later on the IX Workflow
Engine can parse the JWT Model file for specific extensions like the "IX
Mail Extension".
Another aspect of this concept is hat a user of the JWT Editor can
switch on and off the extensions during modeling. So I can see and model
using the Imixs extensions and in the next moment I switch off this
extension and can see the natural model. Than I can switch on a
extension from another vendor to see other aspects of the same model.
This could be also a way to implement real round-trip-modelling.
What did you think about this?
best regards
ralph
