OpenPonk (formerly DynaCASE) is an open modeling platform for conceptual modeling. It allows for diagramming, live modeling where changes are immediately visible, simulations for more visual modeling, bi-directional DSLs to link models and text, validations to ensure model quality, code generation from models, and is fully open source. The document introduces OpenPonk, discusses conceptual modeling, and outlines several features of the modeling platform.
