Quote from the Obeo homepage: "Using GMF to do this is 10,000 hours of work"
- The .uml model is the source of all truth
- Associations, navigability, and end ownership
- To edit cardinality from view you can type "role [0..1]" and it will be magically parsed into 2 labels
- provide shortcuts for common tasks
- using properties view is a royal PITA
