  We illustrate how purpose-specific, graphical modeling enables application
experts with different levels of expertise to collaboratively design and then
produce complex applications using their individual, purpose-specific modeling
language. Our illustration includes seven graphical Integrated Modeling
Environments (IMEs) that support full code generation, as well as four
browser-based applications that were modeled and then fully automatically
generated and produced using DIME, our most complex graphical IME. While the
seven IMEs were chosen to illustrate the types of languages we support with our
Language-Driven Engineering (LDE) approach, the four DIME products were chosen
to give an impression of the power of our LDE-generated IMEs. In fact,
Equinocs, Springer Nature's future editorial system for proceedings, is also
being fully automatically generated and then deployed at their Dordrecht site
using a deployment pipeline generated with Rig, one of the IMEs presented. Our
technology is open source and the products presented are currently in use.
