    Introduction

    Business processes in all domains and especially in electric/ electronic industries are increasingly being conducted electronically; a situation which applies to internal processes as well as to the interaction with external partners. To support the necessary information transfer the use of common concepts based on information/classification models is inevitable.

    Concepts specified on a global basis support error-free information sharing. In addition, the dictionaries of concepts may be used as reference collections for setting up master data repositories for product data that serve as company internal information backbones. Thus, costly interpretation and conversion errors may be minimized.

    From the market side, pressure is increasingly being exerted to supply product data in electronic form using commonly agreed concepts and as this pressure grows, it will have a considerable impact on all business processes. For this reason, a seamless exchange of product data, i.e., an exchange that is free from media discontinuities requires a unified, joint approach both for exchanging product data internally within a company or for exchanging product data with suppliers or customers.

    Scope

    IEC Common Data Dictionary (IEC CDD) is an International Standard (IEC 61360-4 DB) and serves as a common repository of concepts for all industrial/technical domains (electrotechnical and non-electrotechnical; e.g. industry, building, energy, healthcare, …) based on the methodology and the information model of IEC 61360 series, and provides

    • unambiguous identification of classes and properties, and their relations;
    • commonly accepted terminology and definitions based on accepted sources such as IEC International Standards, other International Standards, industry standards, or public authorities;
    • hierarchies of concepts enabling users to appropriately characterize their products and services;
    • relevant conditions and constraints if necessary on possible values of characteristics;
    • technical representation of concepts including units and data types and their identification.

    The above may be used as templates or structures for defining company-specific data collections for various applications, such as catalogues, databases, and master-data repositories. Such consistent data collections are indispensable for data integrity, system engineering, and efficient management of corporate product and service portfolios.

    The license conditions allow the use of the classes, properties, units, values and relations in business and engineering processes and related applications.

    NOTE: IEC CDD data can be extracted in an IEC 62656-1 compliant machine-sensible form.
