What I meant by extended is bring them to the database and the
frontend. Most of the DDD focus I saw was on the core backend domain objects.

I find it refreshing to have an domain event (or any other building
block) with same name and structure in the frontend, backend and the
database. This makes working with it and extracting value a lot easier.

We've tried to design declarative syntax to be writable by programmers
and readable by experts and so far we've had mixed success with
experts. But it really improved communication between various developers
since it gave them a single point of reference and automatic
maintainability.
