5 IEC Extends the package of the CIM, where the core CIM is defined by IEC 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

6 CIM Packages

7 CIM Extensions Modeling of electrical distribution, extending Wires package Added package to CIM: Assets Consumer Documentation Work ERP_Support (leverages OAG)

8 Use Cases

9 IEC 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-to- point messaging

13 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

15 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
