A Brief History: The Common Information Model – IEEE Power

CIM is not an API that allows one to build a power system EMS application and "plug" it into any compliant EMS. A parallel effort that also contributed to the CIM development was the EPRI Operator Training Simulator (OTS) project, which had the goal of developing a training simulator that could be used by any EPRI member.
