The Systems Biology Graphical Notation (SBGN) is a standard graphical representation crafted over several years by a community of biochemists, modelers and computer scientists. SBGN languages are intended to foster the efficient storage, exchange and reuse of information about signaling pathways, metabolic networks, and gene regulatory networks amongst communities of biochemists, biologists, and theoreticians. The simplicity of SBGN syntax and semantics makes SBGN maps suitable for use at the high school level. SBGN is made up of three orthogonal languages for representing different views of biological systems: ''Process Descriptions'', ''Entity Relationships'' and ''Activity Flows''. Each language defines a comprehensive set of symbols with precise semantics, together with detailed syntactic rules regarding the construction and interpretation of maps. Using these three notations, a life scientist can represent in an unambiguous way networks of interactions (for example biochemical interactions). These notations make use of an idea and symbols similar to that used by electrical and other engineers and known as the block diagram Some software support for SBGN is already available, mostly for the Process Description language. == SBGN Process Description language == The SBGN Process Description (PD) language shows the temporal courses of biochemical interactions in a network. It can be used to show all the molecular interactions taking place in a network of biochemical entities, with the same entity appearing multiple times in the same diagram.〔Moodie SL, Le Novère N, Demir E, Mi H & Villéger A.
