Graphical DSL – UCD or MDD?

Hello,

i have a question about Domain Specific Languages.
I've been researching DSLs and I've come across Domain Driven Design or Model Driven Engineering again and again.

More specifically, I wanted to find out whether the approach in the design of a DSL is also transferable to a graphical DSL for e.g. visual programming?

The graphical DSL is supposed to be very end-user oriented, so I considered to focus more on the user-centered design.

Does anyone know that graphical DSLs are more user-centered and focus on the user's ability to interpret and level of knowledge?
I am not sure how i can include a Domain Model in a User Centered Process…
Thanks for your answers 🙂
