A methodology for managing model extensions when using the common information model for systems integration

The promise of standards-based systems integration of utility software applications using the industry standard Common Information Model (CIM) is currently hindered by a practical method for managing model extensions. This paper presents a simple methodology for extending the CIM that utilizes common software tools and standard XMI file format. This methodology is applicable to any utility integration project that uses any of the commonly used integration platforms including Service Oriented Architecture (SOA), Web Services, Enterprise Application Integration (EAI), and Enterprise Service Bus (ESB).
