Constraining Concrete Syntax via Metamodel Information
The Syntax Manager (SYNM) for interactive construction of visual rewriting systems allows users to specify visual languages, by compounding the definition of concrete syntax with metamodel information on the role alphabet elements can play. A concrete rule definition is constrained to comply with the admissible relations for the roles of the elements in it. Hybrid elements can play different roles with respect to different relation
