IEC Errata

2. Introduction
The purpose of this presentation is to document errors discovered in the FDIS for IEC
This should provide key input to the second edition IEC

3. Use of ‘Get’ for MeterReadings
Some sequence diagrams incorrectly use ‘create’ instead of ‘get’ for requesting meter readings
Specific figures in error include:
Section , figure 25
Section , figure 27
Section , figure 34
Section , figure 35
Section , figure 39
Section 5.8.1, figure 47
The following 6 slides provide the revised sequence diagrams correcting verb usage
It is still important to note that these diagrams are examples and are not normative

10. EndDeviceAssets Profile
The following elements are needed, but are not consistent with stricter profile definition rules:
MeterAsset.formNumber
MeterAsset.kH
MeterAsset.kR
The profile will need to be revised to allow for a MeterAsset instead of a more generic EndDeviceAsset
Seal.kind needs to be defined as an enumeration, not a reference
This will impact future versions of the corresponding XSD in appendix H

11. CustomerMeterDataSet Profile
The following elements are needed, but are not consistent with stricter profile definition rules:
MeterAsset.ServiceCategories
The profile will need to be revised to allow for a MeterAsset instead of a more generic EndDeviceAsset
This will impact future versions of the corresponding XSD in appendix H

12. MeterReadings Profile
Need to make Status a concrete type
Need to note that ReadingTypes are optional, as in practice they do not need to be communicated
Might potentially need to expand enumerations for units on ReadingTypes or remove them altogether

13. Notes on Profile Namespaces
These are notes, not errata …
IEC uses the namespace
Some legacy XSDs use a namespace that reflects 2007
The second edition of will use a 2010 or 2011 namespace as appropriate

14. CIM Issues
Need to correct cardinality to make a DemandResponseProgram optional (i.e. 0:1|0:*)

15. Outside of
In Message.xsd, Request.StartTime and EndTime are typed as a string, when they should be xsd:dateTime
