BGML – a novel XML format for the exchange and the reuse of bond graph models of engineering systems

The paper proposes a novel XML based format called BGML that aims at supporting the exchange and the reuse of bond graph models of engineering systems between various bond graph and non-bond graph software. The validity of a BGML description of a bond graph model can be verified against an XML schema. Model equations and constitutive relations (linear or not) are represented in MathML. The concept of BGML is illustrated by means of a small example. In order to demonstrate the usefulness of BGML, an approach to transformations of formats used by bond graph software from and to XML and an export to non-bond graph software, as well as prototypes of their implementation in an experimental open source modelling and simulation environment are discussed.
