Part 8: Web service interface for data parcels
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
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.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62656-8 has been prepared by subcommittee 3D: Classes,

9 FOREWORD
10 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
11 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
12 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
13 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
14 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC
15 Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested
16 in the subject dealt with may participate in this preparatory work. International, governmental and non-
17 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
18 with the International Organization for Standardization (ISO) in accordance with conditions determined by
19 agreement between the two organizations.
20 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
21 consensus of opinion on the relevant subjects since each technical committee has representation from all
22 interested IEC National Committees.
23 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
24 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
25 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
26 misinterpretation by any end user.
27 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
28 transparently to the maximum extent possible in their national and regional publications. Any divergence
29 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
30 the latter.
31 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
32 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
33 services carried out by independent certification bodies.
34 6) All users should ensure that they have the latest edition of this publication.
35 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
36 members of its technical committees and IEC National Committees for any personal injury, property damage or
37 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
38 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
39 Publications.
40 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
41 indispensable for the correct application of this publication.
42 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
43 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
44 International Standard IEC 62656-8 has been prepared by subcommittee 3D: Product
45 properties and classes and their identification, of IEC technical committee 3: Information
46 structures and elements, identification and marking principles, documentation and graphical
47 symbols.

52 INTRODUCTION
53 For description of products and services throughout their lifecycle, an enhanced data
54 interoperability with reduced human interventions is an ultimate goal of developing
55 international standards for intelligent production systems. In attaining this goal, an industrial
56 ontology is expected to play a significant role by allowing components of systems to talk each
57 other, namely machine-machine understanding, about their functions, capabilities, structures
58 and their configurations.
59 The parcellized ontology model defined in IEC 62656-1 also known by its acronym "POM" is a
60 generic ontology model with quadruple layers to capture different types of ontology models by
61 sorting things into categories of homogeneous collection of ontological entities, such as
62 classes (concepts), properties, relations, enumerations, terms (constants), data types, and etc.
63 At the second layer from the top, named Meta-Ontology (MO) layer, eleven types of
64 categories are defined. Each layer is a collection of categories whilst each category is
65 represented by a relational table-like matrix called "data parcel" of which meta data (attributes)
66 are embodied as a selection of instances of the immediate upper layer. The top layer of the
67 POM, named Axiomatic Ontology (AO) layer, just comprises two data parcels which define
68 conjointly the "concept of concepts" by classes and properties, which is an information
69 technology (IT) embodiment of the math-logical notion of the class (i.e., "concept") itself.
70 Subsequent parts of the IEC 62656 standards, which as a whole is collectively known as
71 "Parcel standards", are for specialization of the POM for a specific purpose:
72 IEC 62656-2 is a guide for domain experts to apply the POM for capturing a data dictionary
73 from definitions available from product standards in a form conformant to IEC 61360-2/ISO
74 13584-42 dictionary schema (i.e., common data dictionary model, or CDDM for short) and
75 using the specification of the part as an official data interface for IEC 61360-4 DB known as
76 IEC CDD (Common Data Dictionary), by enabling uploading and downloading of the dictionary
77 to and from the IEC CDD. A referential implementation of this part is available as a tool, free
78 of charge for standardization purposes.
79 IEC 62656-3 is intended as a mapping specification between a standard data model of the
80 "Smart-Grid" domain acronymed as CIM (Common Information Model) and an extended or
81 rather generalized data model of the IEC CDD, namely the POM. The CIM comprises IEC
82 61968/61970/62325 series of standards. Thus, the IEC CDD can accommodate the CIM,
83 provided the IEC CDD sufficiently implements POM as data interface or database.
84 Alternatively, this mapping inevitably entails a small but significant extension of the IEC CDD,
85 without which the accommodation of the CIM into the IEC CDD is infeasible. Nevertheless,
86 there is nothing to add to or subtract from the tool which is currently used as a data interface
87 for the IEC CDD and which fully embodies IEC 62656-1.
88 IEC 62656-5 is intended as an interface for description of activities as an ontology conformant
89 to IEC 62656-1, thus opening a way to store definitions available from activity-centric
90 international standards, for instance IEC 62224-3, as an ontology. This part can also be
91 applied to the description of non-manufacturing use-scenarios, such as, for the description of
92 activities of natural hazard management or electronic tourist guidance or navigation, with a
93 harmonious integration of activities with related products and services.
94 This means a common ontology repository (say, “COR” for short, herein) based on the POM
95 can store both the IEC CDD and the CIM types of data dictionaries or ontologies. Furthermore
96 it can smoothly bridge the differences and fill the gaps covering ontologies of different
97 provenances.
98 The remaining parts of IEC 62656 series are expected to shed a light on a new spectrum of
99 applications for the COR based on the POM.
100 Amongst all, IEC 62656-8 is intended for the description of basic web-services for semantic
101 repositories based on the POM, whilst an advanced type of web-interface including complex

102 enquiry about product as well as query forwarding to another repository is left to a future Part
103 of the series to be developed.

111 1 Scope
112 This document specifies a web service interface based on JSON [1] and XML [2] for
113 transporting over the Internet or an extranet network a set of ontological data conformant to
114 IEC 62656-1. This web service allows an exchange of data parcel(s) between a parcel server
115 and a parcel client or between parcel servers. The data parcel(s) used therein comprises one
116 of the parcel ontology layers, i.e., Axiomatic Ontology layer (AO), Meta-ontology layer (MO),
117 Domain Ontology layer (DO) or Domain Library layer (DL), the detail of which is defined in
118 IEC 62656-1. This interface comprises three basic services, registration service, resolution
119 service and subscription service. With respect to
