Technical Trends in ISO/IEC Joint Technical Committee 1

Abstract

The International Organization for Standardization (ISO)/International Electrotechnical Commission (IEC) Joint Technical Committee (JTC) 1 is an organization established by ISO and IEC and is responsible for international standardization in the field of information technology. This article introduces the activities being addressed by subgroups directly under JTC 1, which were identified in Resolutions from recent ISO/IEC JTC 1 Plenaries.

Keywords: ISO/IEC JTC 1, Plenary, Advisory Group

1. Introduction

The International Organization for Standardization (ISO)/International Electrotechnical Commission (IEC) Joint Technical Committee (JTC) 1 [1] was established by ISO [2] and IEC [3] and is responsible for the international standardization of information technology. Formerly, ISO/Technical Committee (TC) 97 (established in 1960) and IEC/TC 53 (established in 1961) independently promoted standardization activities in the information-technology field, resulting in the duplication of certain technical fields between these organizations [4]. JTC 1 was established in 1987 to solve this problem. The secretariat of JTC 1 is the American National Standards Institute (ANSI). As of September 2023, JTC 1 comprises 40 P-members (active participants) and 62 O-members (observers).

The Plenary is JTC 1’s highest decision-making meeting, and the main agenda is as follows:

Establishment and/or disbandment of Subcommittees (SCs), Working Groups (WGs), and Advisory Groups (AGs) under JTC 1
Appointment of JTC 1 Officers
Revision of operational rules
Reports on SC activities

2. Organization of ISO/IEC JTC 1

The organization of JTC 1 is shown in Fig. 1. The development of standards is carried out by 23 SCs and 5 WGs directly under JTC 1. Discussions on management issues, such as the review of Directives, and on technology issues, such as examination of issues with a view to development of future standards, are carried out by AGs under JTC 1. JTC 1 has established liaisons with organizations other than JTC 1, including IEC/TC 65 (Industrial-process measurement, control, and automation), IEC/TC 100 (Audio, video, and multimedia systems and equipment), ISO/TC 215 (Health informatics), ISO/TC 307 (Blockchain and distributed ledger technologies), ITU-T (International Telecommunication Union - Telecommunication Standardization Sector), and Ecma International.

Japan has been in a significant position regarding the management of JTC 1 as follows:

P-members in all 23 SCs and 5 WGs directly under JTC 1
Chairs of SC 2 (Character code), SC 23 (Digital storage media), SC 28 (Office equipment) and Committee Managers of SC 2, SC 23, SC 28, SC 29 (Media encoding), SC 34 (Document description and processing language)
Approximately 90 Project Editors (as of the end of March 2023)
Hosts of JTC 1 Plenary (4 times)

JTC 1 Plenary has been held twice a year (spring and fall) since 2019. The two most recent JTC 1 Plenaries were held in Tokyo (Japan) in November 2022 and in Paestum (Italy) in May 2023, both in the format of “face-to-face mode with some remote participants”^*1. At both Plenaries, Japan has greatly contributed to steering JTC 1 by proposals through more than a dozen contributions, participation in the Drafting Committee and hosting Tokyo Plenary^*2, which was the first face-to-face JTC 1 Plenary during the COVID-19 pandemic.

The following sections introduce several trends in JTC 1 subgroups and activities for JTC 1 in the Japanese National Body (NB)^*3.

*1	“Face-to-face mode with some remote participants” is the name of a meeting format that uses both face-to-face and virtual modes, as defined in Standing Document (SD) N 19 (Meetings) of ISO/IEC JTC 1. Although this SD defines a similar meeting format “hybrid mode,” there are differences between these two formats, such as the maximum meeting hours per day and whether remote participants have the right to pause the meetings when they lose remote connectivity.
*2	When preparing to host JTC 1 Plenary in Okayama (Japan) in November 2020, the format of the Plenary changed to virtual due to the COVID-19 pandemic. Japan therefore re-invited the Plenary in November 2022.
*3	NB: ISO uses the term MB (Member Body), and IEC uses NC (National Committee). As ISO/IEC JTC 1 is common to both organizations, it is called NB.

3. Latest trends in JTC 1 subgroups

3.1 SC on information technology for smart cities

In JTC 1, WG 11 addresses standardization items related to information technology for smart cities. To coordinate activities related to smart community infrastructure between ISO TC 268/SC 1 (Smart community infrastructures) and JTC 1, AG 20 was established according to the Resolution of the JTC 1 virtual Plenary in May 2022. At the JTC 1 Paestum Plenary in May 2023, Chinese NB submitted a contribution describing that a new SC should be established for smart cities, which was addressed by WG 11. During the Plenary, there was a great deal of discussion resulting in no consensus, and the decision was scheduled on approval of Resolutions on the last day. Japanese NB expressed its opposition because of concerns that the scope of the new SC would overlap with that of other organizations related to smart cities. As a result of the vote, the establishment of the 44th SC was approved by a majority of the P-members present at the Plenary. This new SC will be chaired by Heng Qian (China), Convenor of WG 11, and WG 11 will disband when the new SC is inaugurated. Note that this new SC has been approved by the JTC 1 level at the time of writing this manuscript and it will be inaugurated after approval by the votes of the management boards of ISO and IEC (ISO Technical Management Board and IEC Standardization Management Board).

3.2 WG on quantum information technology

The standardization activities of quantum information technology at JTC 1 are initiated by the Study Group (SG) on quantum computing, approved at JTC 1 Stockholm Plenary in November 2018. Taking over its activities as SG, WG 14 was established according to Resolution of JTC 1 virtual Plenary in June 2020, starting the development of standards on quantum computing. At the JTC 1 Tokyo Plenary in November 2022, Preliminary Work Item (PWI) on quantum simulation was approved, and its structure was discussed. It was agreed to expand the activities of the existing WG 14 because it would be inefficient to establish a single WG specific to quantum simulation. The title of WG 14 was renamed from “Quantum computing” to “Quantum information technology,” and its Terms of Reference (ToR) was also changed to support a wider range of quantum information technologies. This WG is chaired by Hong Yang (China) and its ToR is indicated in Table 1.

3.3 AG on JTC 1 strategic direction

AG 21 was established in response to a contribution submitted by Canadian NB to the JTC 1 Tokyo Plenary in November 2022. The purpose of this contribution is to determine JTC 1’s optimal structure, because JTC 1 has not reviewed its structure, governance, or mode of operation in the light of its current mission for more than 20 years although there have been major changes in not only the information and communication technology (ICT) market and technical landscape but also in the way ICT is used in our global society. This AG is chaired by Norbert Bensalem (France) and its ToR is indicated in Table 1.

3.4 Ad Hoc Group on collaboration across domains

Ad Hoc Group (AHG) 4 was established in response to a Japanese NB’s contribution for JTC 1 virtual Plenary in May 2021. The purpose of this contribution is to propose a restructure of WGs addressing application-layer areas, including the restructuring of WG 11 and WG 12. Although the Plenary could not reach a consensus, it decided to continue this discussion by establishing an AHG. Several proposals were contributed by AHG 4 to JTC 1 Plenaries, including monitoring of liaison activities, long-term plan for across-domain activities and transfer of AHG 4 to AG, which were not adopted as Resolutions. This AHG is chaired by Jacqui Taylor (UK) and its ToR is indicated in Table 1.

4. Activities in Japanese NB

In Japan, SCs under JTC 1 and WGs/AGs/AHGs directly under JTC 1 are mainly operated by Information Technology Standards Commission of Japan (ITSCJ)^*4 [5]. Each mirror subcommittee for WG 11 through WG 15 directly under JTC 1 has been established in ITSCJ to share the status of deliberations and address international ballots. Since 2018, JTC 1 Subgroup Subcommittee has been active in ITSCJ, which comprehensively addresses the issues that the AGs are required to participate in as NB. JTC 1 Subgroup Subcommittee shares deliberations of each AG and discusses how to deal with AGs. This Subcommittee also addresses standardization items for SC 43 (Brain-computer interfaces).

In addition, Subcommittee for Directives is active in ITSCJ, as Japanese companies and organizations other than the members of the subcommittee mentioned above are highly interested in ISO/IEC Directives.

SC 17, SC 28, SC 35/WG 1 (Keyboards, methods and devices related to input and its feedback), SC 35/WG 2 (Graphical user interface and interaction), SC 35/WG 4 (User interfaces for mobile and wearable devices) and SC 35/WG 6 (User interfaces accessibility) are operated by the Japan Business Machine and Information System Industries Association (JBMIA). SC 25/WG 3 (Customer premises cabling), WGs under SC 31 and SC 39 are operated by Japan Electronics and Information Technology Industries Association (JEITA).

5. Future Plenaries

The upcoming Plenaries will be held in Berlin (Germany) in November 2023 and Australia (city to be determined) in May 2024.
