IEC TC57 WG14
• Developing IEC 61968
• Focus is to describe the information exchanges between
systems (i.e. A2A and B2B) related to distribution
operations
• Defines integration between a variety of systems including
network management, outage management, work
management, asset management, SCADA, metering, call
handling, …
• IEC 61968-1 architecture specification is transport
independent
• XML used to format message payloads
• Messages defined using nouns and verbs
• Recognizes request/reply and publish/subscribe
messaging paradigms

IEC 61968
• Extends the 61968 package of the CIM, where
the core CIM is defined by IEC 61970-301
• Integration defined using XML messages
• Messages have a header and a payload
• Header identifies a noun and a verb
• Payload uses CIM-derived type definitions as
described using XML Schema
• Can be used for SOA implementations

IEC 61968 Messages
• Message has header, with optional request, reply and
payload sections
• Header includes information such as a verb, noun,
timestamps, revision, source, replyAddress, …
• Supports request/reply, publish/subscribe and point-topoint messaging

Steps in Defining Messages
• Generate XML Schema complex types
from the CIM (once)
• Develop use cases
• For each use case, identify message
sequences in terms of verbs and nouns
• For each message define XML Schema,
identifying necessary payload content in
terms of references to CIM complex types

Status
• Last meeting held October 2005 in St. Louis,
attended by 19 persons
• Next meeting to be held January 2006 in
Switzerland
• Parts 1 and 3 have been completed, but will be
updated to reflect agreed use of XML Schema
• Most work is currently being done on parts 4, 6,
9 and 12
• Need to get WG14 CIM changes stabilized into
base CIM
