GridWise Interoperability Framework Role of CIM

TC57 Reference Architecture CIM UML Private UML Extensions Bridge Other Information Models Context Message Syntax Profile Message XML Schema Contextual layer restricts information model Constrain or modify data types Cardinality (may make mandatory) Cannot add to information model Message syntax describes format for instance data Can re-label elements Change associations to define single structure for message payloads Mappings to various technologies can be defined Information Model

Ex: Power Flow Network Model Exchange Information Model Defines all concepts needed for exchange of operational load flow models – Reused parts – New extensions Contextual layer restricts information model Specifies which part of CIM is used for static model exchange Mandatory and optional Restrictions But cannot add to information model File syntax Can re-label elements Change associations to define single structure for message payloads Mappings to various technologies can be defined CIM UML Profile CIM/XML RDFSchema Concrete Message Conforms to IEC CIM Conforms to IEC Model Exchange Profile Conforms to IEC CIM XML Model Exchange Format
