WG 13 CIM Issues and Update Report
Updated 2009-11-09
1. Introduction
This document summarizes the CIM issues and changes for CIM 14 up to the document
date. Included are changes from IEC 61970 CIM13 (CIM13v19) to the current working
draft listed under Referenced Documents.
Change tracking is contained in the Microsoft Word version of this document from the
previous release of this document.

3. Process for Content of this Document
This document was created to reflect all open issues in the referenced issue spreadsheet.
Each open issue appears one time in this document under one category that most closely
represents the issue. As issued are closed they will remain in this document and be
presented as closed issues in the final CIM14 report. This document will be updated
throughout the year to facilitate discussion and will ultimately become the final issue
report for the CIM14 release.
4. CIM14 Release
4.1.Changed in CIM 14
All changes to the UML for IEC61970CIM14 are documented in reference [2]. It is
assumed all changes for CIM14 are based on the release of CIM13r19 as the official
CIM13 release. Highlights of changes include:
Extensions added to support UCTE exchange
Company class removed.
Moved several classes from 61970 to Assets package in 61968
HeatExchanger class removed.
Removed datatypes ShortLength and LongLength and replaced them with Length.
Removed classes Load, CustomerLoad, and InductionMotorLoad.
