What is the CIM?
•
•
•
•
A Unified Modeling Language (UML) based information model representing realworld objects and information entities exchanged within the value chain of the
electric power industry
– Maintained by IEC in the Sparx Enterprise Architect modeling tool
Enable integration of applications/systems
– Provides a common model behind all messages exchanged between systems
– Basis for defining information exchange models
Enable data access in a standard way
– Common language to navigate and access complex data structures in any
database
• Provides a hierarchical view of data for browsing and access with no
knowledge of actual logical schema
– Inspiration for logical data schemas (e.g., for an operational data store)
Not tied to a particular application’s view of the world
– But permits same model to be used by all applications to facilitate information
sharing between applications
Benefits of Using CIM
•
•
•
•
•
Data model driven solutions leads to interoperability
Provides common semantics for information exchange between heterogeneous
systems
Provides for automatic generation of message payloads in XML
– Ensures common language for all messages defined
– Avoids proprietary message formats from vendors
– Eliminates work of creating XML tags for each message
– Alternative to EDI or CSV file formats
Uses industry standard modeling notation

CIM Documentation
•
CIM documentation is split into 5 major categories
– 61970-1: Guidelines and General Requirements
• Describes the component based reference model
• Includes general capabilities for integration infrastructure
– 61970-2: Glossary
– 61970-3xx: Common Information Model
• 301: Paper copy of the model
– Published yearly by IEC
– Latest version: CIM13, v19
– Electronic copy on CIMug web site
– 61970-4xx: Component Interface Specifications (CIS)
• Interfaces that a component should implement to be able to exchange information with other
components
• Information content (messages) that a component exchanges
• 2 major divisions
– 401 – 449: Generic service specifications
– 450 – 499: Specific information exchange requirements
– 61970-5xx: CIS Technology Mappings
• RDF Schema, Web Services Profile, OWL Schema, XML format, Graphics Exchange
Who is IEC and UCAIug?
• The International Electrotechnical Commission (www.iec.ch) is
“the world's leading organization that prepares and publishes
International Standards for all electrical, electronic and related
technologies”
• UCA International Users Group (www.ucaiug.org), a non-profit
dedicated to promoting standards, has Liaison status with IEC
– CIM Users Group (www.cimug.org) is one of several groups
within UCAIug
– UCAIug and CIMug members can review draft standards
– Non-Members can not access draft standards
