This part of IEC 62325 defines a restricted (see introduction) example business model of the electricity market following the Open-edi reference model ISO/IEC 14662. Fundamental to the model is the division of the business transactions into the Business Operational View (BOV) and the Functional Service (FSV) with mapping of services between to ensure independence of the communication technology used. Because energy markets vary, this model example is only informative. The main purpose of the model is to show how the modelling methodology can be applied to the energy market, and to serve as the base of technology-dependent configuration examples in other parts of the IEC 62325 series. The model uses the UN/CEFACT modelling methodology UMM based on UML (Universal Modelling Language) for the Business Operational View, but other modeling methodologies may also be used. The modelling is done from the beginning for the whole market and its result is the “business process and information model” which can be taken as the input for the technology-dependent modelling in the design phase of systems and further for the Functional Service View. See IEC 62325-501 and future parts of the IEC 62325 series for this.
