Data Integration Anarchy!
Integration anarchy is a chaos of:
(1)
(2)

(4)
(5)
Without
duplicated logic,
Common
Semantics,
duplicated data,
Point-to-Point
duplicated effort,
Integration Will
newly acquired integration difficulties,
Continue at the
Data Level
lack of ability to easily create new application functionality from
services, and
(6) lack of ability to support business processes with applications
Integration anarchy will result in higher costs and an inflexible, brittle Smart Grid

• A noun, to identify the
type of the payload
• The payload, which
contains the data
relevant to the
information exchange
as defined using a
profile

Slide 9
Message Header
Field
Description
Verb
This enumerated list of verbs can be used to form message types in compliance
with the IEC 61968 standard
Noun
The Noun identifies the main subject of the message type, typically a real world
object defined as a profile using the CIM.
Revision
Revision level of the message type.
Context
Intended context for information usage such as production, testing and etc.
Timestamp
Application level relevant time and date for when this instance of the message type
was produced. This is not intended to be used by middleware for message
management.
Source
Source person or system that publishes the message
AsyncReplyFlag
Indicates whether or not reply should be asynchronous
ReplyAddress
Address to be used for asynchronous replies
AckRequired
Indicates whether or not an acknowledgement is required
User
User information of the sender
MessageID
Unique message ID to be used for tracking messages
CorrelationID
ID to be used by applications for correlating replies
Comment
Optional comment
Property
Message properties can be used to identify information needed for extended
routing and filtering capabilities.

Slide 10
Message Types Are Created By Combining IEC 61968 Verbs With
Information Exchange Topics, Referred To As Nouns
Verbs
Meaning
CREATE
The CREATE verb is used to publish a request to
the master system to create a new document.
CHANGE
The CHANGE verb is used to publish a request to
the master system to make a change in the
document based on the information in the
message.
The CANCEL verb is used to publish a request to
the master system to cancel the document. The
CANCEL verb is used when the business content
of the document is no longer valid due to error(s).
The CLOSE verb is used to publish a request to
the master system to close the document. The
CLOSE verb is used when the business document
reaches the end of its life cycle due to successful
completion of a business process.
The DELETE verb is used to publish a request to
the master system to delete the document. The
DELETE verb is used when the business
document should no longer be kept in the
integrated systems either due to error(s) or due to
archiving needs.
The GET verb is used to publish a request to the
master system to get the current data for a given
document reference code or a set of documents.

Meaning
The CREATED verb is used to publish the
creation of a document as a result of either an
external request or an internal action within the
master system of that document.
The CHANGED verb is used to publish the
change of a document as a result of either an
external request or an internal action within the
master system of that document.
The CLOSED verb is used to publish the normal
closure of a document as a result of either an
external request or an internal action within the
master system of that document.
The CANCELED verb is used to publish the
cancellation of a document as a result of either an
external request or an internal action within the
master system of that document.
The SHOW verb is used to publish the most
current content of a document as a result of either
an external GET request or an internal action
within the master system of that document.
The REPLY verb is used to publish the processing
result of an external request to the master system
to create, change, delete, cancel, or close a
document. The REPLY message type could
contain specific confirmation information as to
whether the request is processed successfully or
not and provide alternatives if applicable.
The SUBSCRIBE verb is used to publish the
request to ask the master system of a document
to publish a CHANGED document whenever there
is a change to the document.
The UNSUBSCRIBE verb is used to publish the
request to ask the master system of a document
to stop publishing a CHANGED document
whenever there is a change to the document.

Network Data Set
– Contains data for any part of a distribution network:
•
•
•
•
•
Typically selected for operational or extension planning studies
Used in numerous implementations for GIS to DMS integration
Can be part of a feeder, a single feeder or more than one feeder
Can be either the ‘As built’ network or a proposed network selected for analysis
It is a superset of IEC 61968-13 CDPSM (i.e., Distribution’s CPSM)
– Contains references to other static data such as:
•
•
•
•
•
Elements of a TypeAssetCatalogue
Elements of a AssetCatalogue
Assets performing the roles of the associated types of PowerSystemResources
Other “leaf node” elements such as Organisations, Locations, and
Measurements
Change Set
– Contains updates required in a transaction for an existing
NetworkDataSet
– Each step in the ChangeSet is described through a separate ChangeItem.
• A change item identifies the change type (add, delete, modify)
• Sequence number for a particular change within a set of changes of a
ChangeSet.
– Only the identifiers of the relevant NetworkDataSet messages are to be
included in a ChageSet message.
• The actual contents are provided in accompanying NetworkDataSets
messages.

Key Collaboration Concept for
the SG-Systems Working Group
• Standard building blocks are defined by standards
development organizations (SDOs)
• Requirements (use cases) are gathered from helpful
sources
– Utilities
– Industry initiatives
• The SG-Systems WG articulates Industry Best
Practices (see next slide) that satisfy requirements
through the use of standard building blocks.
– Recommended extensions and changes to standard building
blocks are provided back to appropriate standards bodies.

Common Concerns About The CIM for Integration
– Concern 1: the CIM is too large
• For the common systems language, the CIM can be thought of as the
unabridged dictionary. It is important to note that projects only use the
portion of the dictionary relevant to their implementation
• But as the dictionary is is much richer, there will be consistency and
congruity for other areas that the implementation must interface with.
– Concern 2: the CIM inhibits innovation
• Because people don’t have to waste time re-inventing things that have
been well vetted in the community, they can leverage the existing
dictionary while focusing more energy on their innovative concept.
• Not only is this more efficient for the innovator, but it is also much more
efficient for the people the innovators wants to share his ideas
with. The community is already educated on how to use the well vetted
language.
– Concern 3: the CIM is too slow
• This is like saying the English language is slow; it is based on the
speakers command of the language and the choice of media used.
• When a person communicates with someone, they must:
1. Articulate the information for the receiver to comprehend it
2. As a person may then provide this information through the US Postal
Service, through email, through phone calls, etc., the system may
provide this information over many types of middleware (messaging,
file transfers, data base, etc.)

Common Concerns About The CIM for Integration (continued)
– Concern 4: The CIM is too abstract
• This quality enables the CIM to continue to be relevant and valid even as
technology continuously changes. The ability to properly convey
unambiguous information primarily boils down to one’s skills in applying
the common systems language.
– Concern 5: The CIM is not a best practice data model
• For any individual purpose, one can always invent a model that is
superior to any other existing model.
• The CIM has not been developed for only one functional area, but rather
by a wide range of domain experts for integrating disparate applications.
So for inter-application integration purposes, a superior model does not
exist and would be difficult to achieve.
– Concern 6: The CIM is too hard to implement
• Specialized models are often biased for a particular implementation and
used with the a specific implementation technology. If the implementation
never had to interface with other systems, this would be easier.
• As the CIM is an information model that is technology neutral, using the
CIM does require following a process that restricts the general information
model for particular contexts and then generates the appropriate design
artifacts. The CIM Community has been doing this for some time and
many tools are available for automating the process.

Thank you for your time!
• Good news: The CIM is being used
extensively – so learning about it is time
well spent.
• Bad news: The CIM continues to need a
lot of work and therefore users must be
prepared for revision management
• Fun news: The CIM is a key NIST
standard – so we have many exciting
adventures (HAN, DER, PEV, ADE, DR,
etc.) to look forward too!
