Hi Buns, you're last question was:

can you explain me the directory structure of the uml14 src dir
(dilayouting, diutils, metamodel, plugin, trashmgmt) ?

=21=21 THIS PART IS PARTICULARY UNDER DEV=21=21=21=21=21

This will be changed, but briefly:

dilayouting:

  - Provide Diagram Interchange Based layouting: You can define policy for=
 node that contain others...What to do when a child is moved, resized, how=
 to share a gain af size with childrens...This part will be completly refa=
ctored (but I don't know how nore when) and putted in a Diagram Interchang=
e specific layer....

diutils:

  - For the moment, only a concrete implementation of Point and Dimension =
interfaces from the Diagram Interchange (these are components not entities=
 so a point is like an integer but not a UML entity (like class, associati=
on...))

metamodel:

  -Contain the implementation of the MetaModel core Extension point...
This is where UML14 modeling packages are loaded, exported...

look at UML14 plugin.xml you see that UML14 extend the MetaModel extension=
 point with this class... I didn't try to extend metamodel with javascript=
 but this is not valuable for the moment because the metamodel logic is on=
ly to deal with the MDR...

plugin:

  - With eclipse every plugin can have a class that control youre plugin l=
ifecycle (look at plugin.xml) UML14Plugin is this class for the UML14 Plug=
in and CorePlugin (in the core plugin)....Core Plugin ....

- trashmgmt

 This part will be moved to an eventual MDR specific layer....
This part as to answer to a simple problem : How to undelete???

Is seems simple but it was very hard because it was like undeleting in a M=
ySQL environement... So briefly (look at the code for more...)... Instance=
s are never deleted directly, instead all their associations are removed a=
nd stocked to put them again if needed... Then the trash is putted in a ma=
p... so when clients want to access directly to the objects (Like ...Packa=
ges.getAllOfType()....) they have to check if the object is not trashed...=
But when they navigate to object (80% of the time) evrything is
transparant....

By....
