 Number of standards in development 6
 Based on IEC DB procedure defined in Annex ST of
IEC directive, member countries cooperate for the
maintenance of IEC61360 CDD (Common Data
Dictionary)
 Strong support from European and Japanese
companies and standard organizations
SC 3D
Cooperation of IEC SC3D with other
TCs/SCs in ISO and IEC
SC 3D
Core standards of IEC SC3D
 IEC 61360 series for “Common Data Dictionary” basics
 Product ontology (data dictionary) model covering all the IEC domain
 Data model is shared by both ISO and IEC, as ISO13584-42 and IEC61360-2.
 Part4, known as IEC 61360 CDD, is the cross-domain repository of metadata for IEC.
 All parts are listed as basic reference in ISO/IEC Directive Part2.
 The standard series is confirmed as one of the first set of standards for Smart Grid by
CEN, CENELEC, ETSI ( sometimes by the code of EN 61360 )
 IEC 62656 series for “Interface and Extension” of IEC CDD
 Specification of ontology elements in a set of tabular forms, e.g., spreadsheets, or
relational tables.
 This is to provide input/output interface for IEC61360 CDD.
 Physical means of exchange may be CSV, XLS, XLSX, XML or any other
 Data model (POM) extends the IEC CDD model, and adds capacity to model itself and
evolve over time.
 IEC 62720 for dictionary of Units of Measurements
 Data dictionary for unique identification of UoMs not only of SI but also non
SI units including Imperial units, to be incorporated into IEC CDD.
 To be referenced by other standards and applications.
 In collaboration with IEC TC25 (units of measurement)

electro technical meta-data for all TCs/SCs

Recent foci of activities
 IEC/CD 61360-1 Ed. 4 (Ed.3 is in use over years)
 IEC 62656 series grows
 IEC 62656-1 “logical structure of data parcel” is now IS
 IEC/FDIS 62656-3 “Interface for Common information model”
 IEC/CD 62656-5 “Interface for activity description”
 Many change requests in a year to IEC CDD content
 CR28 Geometric properties
 CR38 IP code
 CR39 Material Declaration
 CR40 Plasma display panel
 CR41 Unit of measurement dictionary
 CR42 Wireless communication
 CR43 Flash memory
 CR44,45, 46 Plant Devices
 CR47 Logic IC

SC 3D
Social and industrial driver for SC3D standards
 For semantic description, identification, and resolution
of technical concepts based on IEC 61360 series, its
interface IEC 62656 series, and IEC62720 for
identification of unit of measure are considered as
“essential for implementation of Industry 4.0”

Advantages of IEC CDD: Extend or
update an IS in 4 to 6 months
 More information such as material, manufacturer, spare part etc., is accessible.
 Add properties and modify the specifications become much faster
 Modification history of each object is traceable in the IEC CDD

 Part-1 : Explanation, instructions, and interpretation
about the common data model defined in Part2
 Standardization for Ed.4 is underway
 Part-2 : Common data dictionary data model shared
with Part42 of ISO 13584
 Part-4 : Online database, known as IEC CDD of meta
data, used for the description of electrotechnical
products and services, managed according to IEC
supplementary directive--Annex J. Consequently, the
registered items have the status of International
Standard.
 Part-5 : Supplementary definition of data model
corresponding to ISO 13584-25

IEC 61360-4 Common Data
Dictionary (CDD)
 Data dictionary based on IEC 61360-ISO 13584
common data model. The original content consists of
480 classes and1,656 properties. Besides, there are
classes and properties derived from IEC61987-11,
and IEC62683.
 Being maintained in IEC online database, and
anyone can access free of charge.
 Import and export data interface based on IEC62656-
1 is being built and already operational. Web-service
interface is being planned.

Meta class
A meta class is described by a number of meta-properties
The world is made up of a collection of a few different sets of ontological elements
whose underlying structures are almost uniform, (metameta-)class, property, and relation.

Reference mechanism in IEC61360(PLIB) &
IEC62656(POM)
Every reference is via ID with built-in version
*1 In PLIB & POM, “is composed of” is currently realized with a set of “class
