Overview

IEC 62656-1:2014 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies the logical structure for product ontology data parcels using spreadsheets. This first part of IEC 62656 defines a standardized spreadsheet interface aimed at simplifying the definition, transfer, and registration of product ontologies. The standard provides a comprehensive framework for representing product ontology data in a structured spreadsheet format, promoting interoperability and consistency in ontology management across various applications.

This standard facilitates the creation and exchange of reference dictionaries and library instance data, ensuring alignment with established data modeling languages such as EXPRESS (per IEC 61360-2/ISO 13584-42) and incorporating semantic mappings compatible with DIN 4002. Its methodical approach supports the detailed structuring, versioning, and semantic referencing necessary for complex product ontology data.

Key Topics

• Logical Structure for Spreadsheets
  IEC 62656-1 defines the specifications for the layout and logical organization of spreadsheets used as data parcels. This includes mandatory header sections, instruction columns, and data sections structured for consistent representation of ontology elements.

• Meta Dictionary and Meta-Model
  The standard introduces a meta dictionary to facilitate the definition and transfer of reference dictionaries as instance data. It further defines a meta-model that enables handling meta-meta-dictionaries, supporting hierarchical and layered ontology definitions.

• Semantic Mapping and Data Types
  It specifies the mapping between spreadsheet-expressed dictionary data and the EXPRESS modeling language, ensuring syntactic and semantic compatibility. The standard also extends type systems with specialized data types and supports complex constructs such as classification trees, property specialization, and unit variables.

• Parcellized Ontology Model (POM)
  The POM concept underpins this standard, enabling the modular packaging of ontology data parcels. This model supports layering, parcel identification, version control, and conformance classes, allowing organized and scalable ontology management.

• Use Cases and Scenarios
  Practical scenarios include dictionary parcel formats for ontology definitions, library parcel formats for instance data, and higher-layer parcel formats for complex ontology structures. These use cases demonstrate how product ontologies can be effectively created, shared, and maintained.

Applications

IEC 62656-1:2014 is instrumental in industries and domains where standardized and interoperable product ontologies are critical. Key applications include:

• Product Data Management
  Facilitates harmonized product descriptions, improving data exchange between manufacturers, suppliers, and clients.

• Knowledge Representation in Engineering
  Supports engineers and designers in creating consistent, machine-readable ontologies for product components and systems.

• Supply Chain Integration
  Enables seamless transfer and registration of product ontologies across supply chain partners, increasing efficiency and reducing errors.

• Digital Twin and IoT Systems
  Provides structured ontology data essential for digital twins and Internet of Things (IoT) platforms to maintain accurate and up-to-date product information.

• Standardized Data Exchange Formats
  Aligns with other IEC and ISO standards, creating unified formats for product information that can be easily integrated into enterprise software solutions.

Related Standards

• IEC 61360-2 / ISO 13584-42
  Defines the EXPRESS modeling language used as a reference for mapping product ontology data within IEC 62656-1.

• ISO 13584-25
  Provides additional elements referenced for detailed data modeling in product ontologies.

• DIN 4002
  Offers semantic reference points to ensure basic semantic mapping consistency with the IEC 62656-1 spreadsheet data formats.

• IEC 62656 (other parts)
  Subsequent parts of the IEC 62656 series expand on the ontology register and transfer process, complementing the logical structure defined in Part 1.

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.

STANDARDIZED PRODUCT ONTOLOGY REGISTER
AND TRANSFER BY SPREADSHEETS –

Part 1: Logical structure for data parcels

1 Scope
This part of IEC 62656 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”. Thus the logical
data structure described in this standard is named “Parcellized Ontology Model” or “POM” for
short, and each vehicle of transport of the model is called a “parcel”, and may be used for
definition, transfer, and registering of a reference dictionary as a collection of metadata, or for
similar purposes for instances belonging to a certain class of the reference dictionary.
Moreover, this ontology model allows for modelling or modifying an ontology model per se as
a set of instance data, thus it enables an ontology model to evolve over time.
This part of IEC 62656 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.
It is assumed that a tool supporting this part of IEC 62656 may read and write a set of
spreadsheet data whose semantics and syntax are defined in this part of standard, where the
physical file structure of the spreadsheets may be based on the CSV (Comma Separated
Values) format, typically used in a commercial spreadsheet application, or any other tabular
formats including XML schema compatible or convertible to the CSV format.
The spreadsheet interface structure defined in this part of IEC 62656 contains the following:
– Definition and specification of the logical structure and layout of the spreadsheet interface
for definition, transfer, and registering of a reference dictionary;
– Definition and specification of library instance data belonging to a class of a reference
dictionary described by a set of spreadsheets conformant to this part of IEC 62656;
– Definition and specification of the meta dictionary that enables the definition and transfer
of a reference dictionary as a set of instance data conforming to the meta dictionary;
– Definition and specification of the meta-model as data that enables the definition and
transfer of a reference dictionary as a set of instance data conforming to the meta-meta-
dictionary
– Specification of the mapping between the dictionary dat
