  • A new Annex A was added providing a model of a circuit breaker in the CIM as an example of how the CIM can be used to model network devices
  • The naming hierarchy was changed.
  • ModelingAuthority and ModelingAuthoritySet classes were added to represent ownership of models.
  • A new schedules data model was added to replace the use of the curve model for time series data.

  • The class naming was renamed to IdentifiedObject.
  • Many editorial corrections, including several cardinality and attribute changes to resolve issues submitted on the first edition.
