Diabelli is the name of our framework that provides infrastructure for extending
existing interactive theorem provers with heterogeneous reasoning. We use the
phrase heterogeneous reasoning (or HR), to refer to theorem proving
involving both diagrammatic and sentential formulae and proof steps.
I will outline the general idea of HR with concepts such as heterogeneous goals,
heterogeneous inference steps, and foreign embedded formulae (or placeholders).
Afterwards, I will present the Diabelli framework itself, its architecture, and
the Speedabelle system, which is an example instantiation of the framework.
Speedabelle uses the framework to integrate Isabelle and Speedith (our
diagrammatic reasoner for spider diagrams). This enables heterogeneous
reasoning with mixed Isabelle/HOL formulae and spider diagrams.
