Diaplan - a language for programming with diagrams

DIAPLAN is being developed since 1999, in cooperation with Frank Drewes (Umeå) and Mark Minas (München). The language shall have the following features:

Graph-based: Data is represented by nested graphs.
Rule-based: Programs are collections of predicates that are defined by graph transformation rules.
Visual: Programs are drawn as graphs and diagrams.
Generic: Data can be given in or displayed in arbitrary diagram notations.
Typed: The shape of graphs is defined by grammars.
Logic: Nondeterminism and backtracking are supported.
Functional: Predicates may be higher-order.
Object-baesd: Predicates are associated to particular types of graphs.

Presently we are still investigating foundations and concepts of the language; an interpreter of its kernel is developed in parallel.
