How is SBML different from CellML?
CellML is another format to encode quantitative models, based on XML like SBML. CellML is being developed by the Bioengineering Institute at the University of Auckland and collaborating groups. The chief differences between CellML and SBML can be perhaps described in the following ways. While a model encoded in SBML is based on the successive, hierachical, declarations of model constituents, a CellML model is built as a network of components. A component can contain variables, mathematical expressions, metadata etc. In CellML, the biological information is entirely stored in metadata rather than the language elements. In SBML, the language elements were more directly influenced by present-day biochemical network simulation software, and the mathematical expressions are more constrained than what is permitted in CellML’s subset of MathML. Although SBML and CellML cannot be fully interconverted at the moment, it is nevertheless sometimes possible. Examples of tools providing this service
