Why to extend ?



Add new links



Add new attributes

Add new subtypes



Icon dependingon the category

Add non-semantic properties

IconLabel color depending on the number of books



Oups…!



Extensibility limitations

What if you are not the author of the metamodel ?

You can’t always change the metamodelex: UML

What to do with existing models ?

Existing Instances can’t change their typeEx: Book -> ScienceFictionBook

What if your extension is specific to a working context ?

You can’t dynamically create/load/unload extensionsEx: Statistics, Shortcuts, Viewpoint, etc.
