Overview

IEC 61968-4:2007 defines message content and system interfaces for records and asset management in electric utility distribution management. Part of the IEC 61968 series, this standard specifies a set of interoperable message types to exchange network, asset and catalogue information between loosely coupled applications in a Distribution Management System (DMS). It is of core relevance to Smart Grid implementations that require consistent, standardized data exchange for planning, operations and asset lifecycle management.

Key topics

• Message types: standardizes content for Network Data Set, Change Set, Presentation, Asset List, Asset Catalogue and Type Asset Catalogue messages.
• Static information model: message fields are drawn from a common information model (CIM classes), ensuring consistent attribute names and types across systems.
• Interface reference model: aligns with the IEC 61968-1 IRM to support inter-application integration for distribution management.
• Loose coupling and middleware: intended for heterogeneous environments where applications communicate via message exchange (not tight, intra-application middleware).
• Data referencing: messages may include identifiers that reference external documents or catalogues (e.g., assets, type catalogues) rather than duplicating full definitions.
• Formats & use cases: defines formats for created/changed/shown/deleted NetworkDataSet messages and others to support typical records workflows.
• Smart Grid relevance: supports integration needs for modern grid monitoring, planning, and asset inspection processes.

Applications

IEC 61968-4 enables practical utility use cases such as:

• Network extension planning - exchanging proposed “as-planned” or “as-built” feeder data between planners and analysis tools.
• Copying feeder or network data - transferring portions of the network model between systems (GIS, DMS, planning tools).
• Network/diagram edits - publishing change sets and presentations for collaborative editing and version control.
• Asset inspection and lifecycle management - sharing asset lists and catalogues for maintenance, procurement and field work.
  These message types support exchanges occurring on operational timescales (seconds to hours), complementing batch or warehouse solutions.

Who should use it

• Utility IT architects and data modelers
• DMS, GIS and asset management vendors and integrators
• System integrators implementing Smart Grid interfaces
• Network planners, asset managers and operations teams

Related standards

• IEC 61968-1 (Interface architecture and general requirements)
• IEC 61968-3 (Network operations interfaces)
• IEC 61970-301 / CIM (information model)
• Annex A of IEC 61968-4 references Geography Markup Language (GML) usage for geospatial data

Using IEC 61968-4 helps utilities achieve interoperable, consistent records and asset data exchange across the enterprise-critical for efficient distribution management and Smart Grid modernization.

INTRODUCTION
The IEC 61968 series of standards is intended to facilitate inter-application integration as

opposed to intra-application integration. Intra-application integration is aimed at programs in

the same application system, usually communicating with each other using middleware that is

embedded in their underlying runtime environment, and tends to be optimized for close, real-

time, synchronous connections and interactive request/reply or conversation communication

models. IEC 61968, by contrast, is intended to support the inter-application integration of a

utility enterprise that needs to connect disparate applications that are already built or new

(legacy or purchased applications), each supported by dissimilar runtime environments.

Therefore, these interface standards are relevant to loosely coupled applications with more

heterogeneity in languages, operating systems, protocols and management tools. This series
of standards is intended to support applications that need to exchange data every few
seconds, minutes, or hours rather than waiting for a nightly batch run. This series of
standards, which are intended to be implemented with middleware services that exchange
messages among applications, will complement, not replace utility data warehouses,
database gateways, and operational stores.
As used in the IEC 61968 series, a DMS consists of various distributed application
components for the utility to manage electrical distribution networks. These capabilities
include monitoring and control of equipment for power delivery, management processes to
ensure system reliability, voltage management, demand-side management, outage
management, work management, automated mapping and facilities management. Standards
interfaces are defined for each class of applications identified in the Interface Reference
Model (IRM), which is described in IEC 61968-1.
This Part of IEC 61968 contains the Clauses shown in Table 1.

Part 4: Interfaces for records and asset management

1 Scope
This Part of IEC 61968 specifies the information content of a set of message types that can
be used to support many of the business functions related to records and asset management.
Typical uses of the message types defined in this Part of IEC 61968 include network
extension planning, copying feeder or other network data between systems, network or
diagram edits and asset inspection. Message types defined in other Parts of IEC 61968 may
also be relevant to these use cases.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.
IEC 61968-1, Application integration at electric utilities – System interfaces for distribution
management – Part 1: Interface architecture and general requirements
IEC 61968-3, Application integration at electric utilities - System interfaces for distribution
management - Part 3: Interface for network operations
3 Reference and information models
3.1 General
The message types defined in IEC 61968-4 are based on a logical partitioning of the DMS
business functions and components called the IEC 61968-1 Interface reference model.
As described, in IEC 61968-1, the contents of the message types are based on a static
information model to ensure consistency of field names and data types. Each message type is
defined as a set of fields copied from the information model classes. The message types

defined in this standard are intended to satisfy a majority of typical applications. In some
particular project implementations, it may be desirable to modify the set of fields using a
methodology such as that described in IEC 61968-1.
3.2 Interface reference model
It is not the intention of the IEC 61968 series to define the applications and systems that
vendors should produce. It is expected that a concrete (physical) application will provide the
functionality of one or more abstract (logical) components as listed in this standard. These
abstract components are grouped by the business functions of the IEC 61968-1 interface
reference model.
3.3 Records and asset management functions and components
The Records and Asset Management part of the IEC 61968-1 Interface reference model
shows those functions and typical components that are applicable to the message types
defined in IEC 61968-4.

business functions and components called the IEC 61968-1 Interface reference model.
As described, in IEC 61968-1, the contents of the message types are based on a static
information model to ensure consistency of field names and data types. Each message type is
defined as a set of fields copied from the information model classes. The message types

defined in this standard are intended to satisfy a majority of typical applications. In some
particular project implementations, it may be desirable to modify the set of fields using a
methodology such as that described in IEC 61968-1.
3.2 Interface reference model
It is not the intention of the IEC 61968 series to define the applications and systems that
vendors should produce. It is expected that a concrete (physical) application will provide the
functionality of one or more abstract (logical) components as listed in this standard. These
abstract components are grouped by the business functions of the IEC 61968-1 Interface
reference model.
3.3 Records and asset management functions and components
The Records and Asset Management part of the IEC 61968-1 Interface reference model
shows those functions and typical components that are applicable to the message types
defined in IEC 61968-4.
For the message types defined in IEC 61968-4, it is expected that the typical abstract

components listed below will be producers of information. Typical consumers of the

information are the other components as listed in IEC 61968-1.

3.4 Static information model
The information model relevant to records and asset management consists of classes that

provide a template for the attributes for each message. The classes are defined in detail in

IEC 61970-301 or in future document IEC 61968-11.

4 Records and Asset message types

4.1 Summary
The records and asset message types describe information for the following types of
document:
• network data set,
• change set,
• presentation,
• asset list,
• asset catalogue,
• type asset catalogue.
For all message types shown in IEC 61968-4, elements that correspond with CIM classes
contain all native and inherited attributes of that class. Unless explicitly shown otherwise, all
message type associations are simple associations.
4.2 Network Data Set message type
4.2.1 Message content
A NetworkDataSet message can contain data for any part of a distribution network typically
selected for operational or extension planning studies. The message contents could be part of
a feeder, a single feeder or more than one feeder. The data could be either the ‘As built’
network or a proposed network selected for analysis.
A NetworkDataSet message may contain references to other Documents containing static
reference data such as TypeAssetCatalogue or AssetCatalogue. It may also contain
references to Assets performing the roles of the associated types of PowerSystemResources.

The same is true for other “leaf node” elements such as Organisations, Locations, and
Measurements. In these cases, only the identifier for the referenced data is to be included in
this message type. The actual data for referenced elements are provided through other types
of messages (e.g.,TypeAssetCatalogue, AssetCatalogue, AssetList, Measurements).
The basic structure is a hierarchy as shown in Figure 1. The initial dynamic state of the
network including switch positions is defined as a set of MeasurementValues. These values
can be updated using the ShowMeasurementList message defined in IEC 61968-3.
4.2.2 Message format
Created NetworkDataSet, changed NetworkDataSet, show NetworkDataSet and deleted
NetworkDataSet have the same message formats as shown in Figure 1.

4.3 Change Set message type
4.3.1 Message content
A ChangeSet message type contains updates required in a transaction for an existing

NetworkDataSet, which is referenced in the uppermost hierarchy of this message type. Each

step in the ChangeSet is described through a separate ChangeItem. A change item identifies

the change type (add, delete, modify) and sequence number for a particular change within a

set of changes of a ChangeSet. The changes for this change item are articulated in an
instance of NetworkDataSet, which is a child element of the ChangeItem. Only the identifiers
of the relevant NetworkDataSet messages are to be included in a ChangeSet message. The

actual contents are provided in accompanying NetworkDataSets messages.

The basic structure is a hierarchy as shown in Figure 2.
4.3.2 Message format
Created ChangeSet, changed ChangeSet, show ChangeSet and deleted ChangeSet have the
same message formats as shown in Figure 2.

IEC

4.4 Presentation message type
4.4.1 Message content
A Presentation message can contain location information for most any element represented in
the Common Information Model, particularly elements of the distribution network. It can be
used for providing location information of individual assets or power system resources or to
provide a set of location information as a companion to the NetworkDataSet. The basic

structure is a hierarchy as shown in Figure 3. Refer to Annex A for information regarding the
use of Georaphy Markup Language (GML).
4.4.2 Message format
Created Presentation, changed Presentation, show Presentation and deleted Presentation
have the same message formats as shown in Figure 3.

4.5 Asset List message type
4.5.1 Message content
An AssetList message can contain various amounts of data for any set of utility assets. An
AssetList message may contain references to static reference data such as elements of a
AssetCatalogue or TypeAssetCatlogue. It may also contain references to the types of
PowerSystemResources that specify the role in which the Asset is being used (i.e., if it has
been installed rather than sitting in inventory). The same is true for other “leaf node” elements
such as Organisations, Locations, and Measurements. In these cases, only the identifier for
the referenced data is to be included in this message type. The actual data for referenced

elements are provided through other types of messages (e.g.,TypeAssetCatalogue,
AssetCatalogue, NetworkDataSet, Measurements).
4.5.2 Message format
Created AssetList, changed AssetList, show AssetList and deleted AssetList have the same
message formats as shown in Figure 4.

4.6 Asset Catalogue message type
4.6.1 Message content
An AssetCatalogue is a collection of information regarding available types of products and
materials that are used to build or install an Asset(s), to maintain an Asset(s) or to operate an
Asset(s). Each catagoue item is for a specific product available from a specific supplier. An
AssetCatalogue message may contain references to static reference data such as elements of
a TypeAssetCatalogue or Specifications. The same is true for other “leaf node” elements such

as Organisations. In these cases, only the identifier for the referenced data is to be included
in this message type. The actual data for referenced elements are provided through other
types of messages (e.g.,TypeAssetCatalogue).
4.6.2 Message format
Created AssetCatalogue, changed AssetCatalogue, show AssetCatalogue and deleted
AssetCatalogue have the same message formats as shown in Figure 5.

4.7 Type Asset Catalogue message type

4.7.1 Message content
A TypeAssetCatalog message can contain data for a set of utility asset types. It is a collection
of information regarding generic types of assets that may be used for design purposes,
analysis, and so on. A TypeAsset is not associated with a particular manufacturer. A

TypeAssetCatalogue message may contain references to other Documents containing static

reference data such as elements of a AssetCatalogue. The same is true for other “leaf node”

elements such as Organisations. In these cases, only the identifier for the referenced data

shall be included in this message type. The actual data for referenced elements are provided

through other types of messages (e.g., AssetCatalogue).

4.7.2 Message format
Created TypeAssetCatalogue, changed TypeAssetCatalogue, show TypeAssetCatalogue and
deleted TypeAssetCatalogue have the same message formats as shown in Figure 6.

Annex A
(informative)
Use of the Geography Markup Language (GML)

For presentation purposes (refer to Subclause 4.4), IEC 61968-4 recommends use of the

Geography Markup Language (GML) for the exchange of geographic information for both

utility resources and landbase data. The Presentation message type may be used without
actually employing GML for exchanging elementary rendering data about utility resources.

However, GML provides a much richer set of capabilities that will be useful in many

circumstances. When GML is to be employed, note that use of the appropriate GML elements
is facilitated with the “Gml” prefix on the CIM elements of the Presentation message type.
This should enable implementations to use these two standards together with only minimal
and straightforward transformations being necessary.
GML is an XML encoding for the transport and storage of geographic information, including
both the geometry and properties of geographic features. The key concepts used by GML to
model the world are drawn from the Open GIS Consortium Abstract Specification
(www.opengis.org).
GML provides a variety of types of objects for describing geography including features,
coordinate reference systems, geometry, and topology. A geographic feature is "an
abstraction of a real world phenomenon; it is a geographic feature if it is associated with a
location relative to the Earth” . So a digital representation of the real world can be thought of
as a set of features. The state of a feature is defined by a set of properties, where each
property can be thought of as a {name, type, value} triple.
Geographic features with geometry are those with properties that may be geometry-valued.
A feature collection is a collection of features that can itself be regarded as a feature; as a
consequence a feature collection has a feature type and thus may have distinct properties of
its own, in addition to the features it contains.
The number of properties a feature may have, together with their names and types, are
determined by its type definition. Geographic features with geometry are those with properties
that may be geometry-valued. A feature collection is a collection of features that can itself be
regarded as a feature; as a consequence a feature collection has a feature type and thus may
have distinct properties of its own, in addition to the features it contains.
A coordinate reference system consists of a set of coordinate system axes that is related to
the earth through a datum that defines the size and shape of the earth. Geometries in GML

indicate the coordinate reference system in which their measurements have been made. The
“parent” geometry element of a geometric complex or geometric aggregate makes this

indication for its constituent geometries.
Refer to http://www.opengeospatial.org/standards/gml for further information. The XML
schema for the GML feature object is defined in the file feature.xsd available from
http://schemas.opengis.net/gml/3.1.1/base/.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l’IEC). L’IEC a pour
objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines
de l'électricité et de l'électronique. A cet effet, l’IEC – entre autres activités – publie des Normes
internationales, des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au
public (PAS) et des Guides (ci-après dénommés "Publication(s) de l’IEC"). Leur élaboration est confiée à des
comités d'études, aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les
organisations internationales, gouvernementales et non gouvernementales, en liaison avec l’IEC, participent
également aux travaux. L’IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO),
selon des conditions fixées par accord entre les deux organisations.
