7. A Finmeccanica Company Experience: EMF with XSD Positive –Schema -> Model + Editor –Very easy (fairly basic) editor –Tweaks e.g. class names: add ecore attributes to schema –Easily extensible / customised –Regenerate without losing customisation Limitations –Based on Ecore model (similar to UML) Not fully congruent with Schema – e.g. choice Validation not as rigorous as Schema –Minor UI oddities e.g. default values
