History of the Common Information Model (CIM)
• Late 1980’s-Early 90’s- Informal meetings of Industry focused on “How to achieve “open system design”
• 1993-Formation of EPRI led CCAPI Task Force: “ One vendor did not have all solutions for a customer. Need for integration”
• Initial Goals of CCAPI:
– Provide common information model to facilitate information exchange
– Enable use of plug in applications
– Protect application investment
– Framework for integration of legacy systems

Important Milestones
• 9/1996: CIM initially submitted to IEC; CIM 10 final version accepted for standard in 2001. First major CIM Installation 1998
• Component technology emerged in late 1990’s . CCAPI calls them Component Interface Specs (CIS). Key to facilitating integration in a distributed environment
• Generic Interface Design (GID) initial design submitted to IEC 12/2001 after 2 yrs technical debate and design– SW developers create components w/o concern for underlying
infrastructure– GID guides standard API for an application to exchange/access data

CIM XML Interoperability Tests
• EPRI has sponsored six interoperability tests based on the CIM XML standards:
– Six interoperability tests successfully completed exchanging real-world large scale models (12,000 bus) and several sample models (40 to 100 bus)
• December 2000: Orlando, Florida• April 2001: Las Vegas, Nevada• September 2001: Monterey, California• July 2002: San Francisco, California• November 2003: Cleveland, Ohio• July 2004: Folsom,California
– Validated the use and acceptance of this standard by suppliers who provide products to the electric utility industry
– Test reports available from EPRI

CIM Status and Access Information
• Survey ( 2 years old) shows over 47 CIM installations in US and over 55 applications delivered. New survey to be done in 2005.( How do you count rabbits?) USA started 2+ years ahead of other countries
• Globally accepted now. Known implementations in process or done in Belgium, Brazil, China, France, Ireland, Jordan, Russia, Slovenia, South Africa, Spain, others(?)
