Definition
IEC CDD (IEC Common Data Dictionary)
IEC-hosted system that includes a common repository with data dictionaries for all ISO and IEC industrial/technical related-domains and that complies with the data model for data dictionaries defined in IEC 61360-2/ISO 13584-42 with an enhancement of its modelling capability adopted from IEC 62656-1.
NOTE 1 Data dictionaries may include data from electrotechnical and non-electrotechnical domains.
NOTE 2 Content published in data dictionaries will become ISO or IEC standard.
IEC CDD Management System
System providing functions and integrated services to support the IEC CDD repository management including creation, use and maintenance of the repository with its data dictionaries.
IEC CDD Management System

IEC CDD repository
Collection of standardized data dictionaries managed as a database in IEC CDD.
IEC CDD) Data Dictionary
Structured collection of dictionary elements that complies with the data model specified in IEC 61360-2/ISO 13584-42 and IEC 61360-1, and that represents product ontologies.
Basic publications for IEC CDD
IEC 61360-2 ED3 (2012) Standard data element types with associated classification scheme for electric components
Part 2: EXPRESS dictionary schema
IEC 613602 provides a formal model for data according to the scope as given in IEC 61360-1 and ISO 13584-42, and thus provides a means for the computer-sensible representation and exchange of such data.
The presented EXPRESS model represents a common formal model for the two standards (IEC 61360-2 and ISO 13584-42) and facilitates a harmonization of both.
The IEC 61360-2 forms the master document. ISO 13584-42 contains a copy of the IEC 61360-2 EXPRESS model in an informative annex.
IEC 61360-1 ED4 (2017) Standard data element types with associated classification scheme
Part 1: Definitions – Principles and methods
IEC 61360-1 specifies principles for the definition of the properties and associated attributes and explains the methods for representing verbally defined concepts with appropriate data constructs available from IEC 61360-2.
IEC 61360-6 ED1 (2016) Standard data element types with associated classification scheme for electric components
Part 6: IEC Common Data Dictionary (IEC CDD) quality guidelines
IEC 61360-6 specifies principles for the definition of the properties and associated attributes and explains the methods for representing verbally defined concepts with appropriate data constructs available from IEC 61360-2.
IEC 61360-6 is intended for domain specialists who are technical experts in their specific technical domain.
IEC 62656-1 ED1 (2014) Standardized product ontology register and transfer by spreadsheets
Part 1: Logical structure for data parcels
IEC 62656-1 specifies the logical structure for a set of spreadsheets, used as “data parcels”, to define, transfer and register product ontologies. Such ontology descriptions in other literatures or disciplines are sometimes called
“reference dictionaries” or “concept repositories”. IEC 62656-1 also includes a standard mapping between the meta-data of dictionary parcels in the spreadsheet format conforming to this standard and the meta-data represented in IEC
61360-2 compliant EXPRESS model for dictionary exchange.
Product ontologies are published as data dictionaries in IEC CDD.
International Registration Data Identifiers (IRDI) according to ISO 29002
All items/elements in the data dictionaries have an unambiguous identifier (IRDI) according to ISO TS 29002-5 to support electronic data exchange.
Format of IRDI: RAI#DI#VI.
Example: 0112/2///61360_7#CAA000#001
ICD: 0112=ISO or IEC
OI: 1=ISO; 2=IEC; 3=ISO/IEC
AI: 61360_7=name of data dictionary in IEC CDD
IC: CAA000=item code (limited to 6 digits in IEC CDD)
VI: 001
Data dictionaries published in IEC CDD as product ontologies
IEC 61360-4 – Electric/electronic components
This data dictionary is providing products ontologies for electric/electronic components (intended to be mounted on a printed circuit board) and a class “features” including items/elements for use across all data dictionaries.
NOTE The class “features” will be transferred to the data dictionary IEC 61360-7 in the near future..
IEC 61370-7 – General items
This data dictionary is providing general items/elements for use across all data dictionaries (e.g. common codes for countries, languages, degrees of protection provided by enclosures – IP Code) and the references to selected Asset
Administration Shell (AAS) Submodels.
IEC 62720 – Units of Measurement (UoM)
This data dictionary is providing units of measurement (UoM) including units, quantities, and dimensions. A reference to the “common code” from UNECE Rec. 20 is also provided.
IEC 61987 – Process automation
This data dictionary is providing products ontologies for industrial-process automation.
IEC 62683 – Low-voltage switchgear and controlgear
This data dictionary is providing products ontologies for low-voltage switchgear and controlgear.
IEC 63213 – Measuring equipment for electrical and electromagnetic quantities
This data dictionary is providing products ontologies for measuring equipment for electrical and electromagnetic quantities.
ISO ICS (International Classification for Standards)
This data dictionary is providing a 3-level hierarchical classification and applies to all international, regional, and national normative documents, such as standards, technical reports, standardized profiles, technical specifications, technical regulations, guides, codes of practice, technology trends assessments, etc. and the drafts of such documents.
IEC 63508 – circuit-breakers and similar equipment for household use
This data dictionary is providing products ontologies such as circuit-breakers and similar equipment for household use.
Additional data dictionaries
Additional data dictionaries e.g. “electric motors” (from IEC/TC2), “electric inverters” (from IEC/TC22), “high-voltage switchgear” (from IEC/TC17, and several others are under consideration or processing.
Request to committees
IEC or ISO committees that have developed classification standards are requested to contact IEC/SC3D to publish the classification standards as data dictionaries in IEC CDD.
