 SED-ML encodes in a computer-readable exchange format the information required by MIASE to enable reproduction of simulation experiments. It has been developed as a community project and it is defined in a detailed technical specification and additionally provides an XML schema.
 
-SED-ML Level~1 Version~4 covers the description of time course and steady state simulations, parameter estimation experiments, and introduces a generic construct to allow new experiments to be described without the need to update this core specification.  For all descriptions, SED-ML provides a way to define the data, models, modifications, simulations, analyses, and results of each experiment it describes.  These descriptions are independent of the underlying model implementation. SED-ML is a software-independent format for encoding the description of simulation experiments; it is not specific to particular simulation tools.  Other materials and resources are available from the SED-ML project website at \url{http://sed-ml.org/}.}
