Meta-modelling is important

• Formally defines Domain Specific Language (DSL)

• Allows formal definition and validation of domain knowledge

• DSLs are more efficient for people to learn and model the domain with

• Mappings between DSLs allow interoperability (if only it were that simple :-P )

Possible Issues/Unclear Aspects

• Does their Ontology/linguistic meta-model just extend or (partly) redefine the standard Conceptual Graphs?

• Can the definitions of (csubt) and (rsubt) be extended to support “deep instantiation”? (Do they need to be?)

• Can (type) be used to get non-linguistic layer types?

• Can the ω function be used multiple times? What is the behaviour if the concept does not map to any entities?
