Abstract

Today's macromolecular regulatory network models are small compared to the amount of information known about the corresponding cellular pathways, in part because current modeling languages and tools are unable to handle significantly larger models. Most pathway models are small models of individual pathways which are relatively easy to construct and manage. The hope is someday to put these pieces together to create a more complete picture of the underlying molecular machinery. While efforts to make large models can benefit from reusing existing components, there currently exists little tool or representational support for combining or composing models. In this paper we present a tool for merging two or more models (we call this process model fusion) and a concrete proposal for implementing composition in the context of the Systems Biology Markup Language (SBML).
