Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
With more than half of the world's population living in cities, the city is the place where resources and
economic and social activities are concentrated. As a space carrier for human beings in economic, social,
cultural, and political activities, the city has become a source of technological innovation, an engine
of economic growth, a platform for cultural development, a centre for decision-making, and a node
for external connections. In the context of globalization, the city has become increasingly important.
However, poor management of the city causes states of confusion and disorder, e.g. traffic congestion,
environmental pollution, shortage and waste of resources, which is incompatible with sustainable
development and the UN Millennium Development Goals.
City infrastructures are the foundation of city operations and the goal of city management, including
municipal infrastructures, information and communications technology (ICT) infrastructures (see
ISO/TR 37150). Information and digital technologies, e.g. mobile Internet, Internet of Things, and
systems integration, provide a fundamental basis for infrastructure management. Based on digital
technologies and systems, the digital city management framework can be expanded by integrating
information, ICT and public facilities and services. Meanwhile, the city management database can
be constructed by adopting various data bases from existing city data sources, e.g. environmental
monitoring, traffic monitoring, energy supply, and demographic statistics. The collection and integration
of various factors of city management will improve the data standardization and promote collaboration
across departments and businesses. This can improve the service capabilities of city infrastructures
and contribute to improving processes and services that facilitate and support liveability within the
city. The specific practices of infrastructure governance will depend on the characteristics and actual
demands of the city and considering protection of data privacy, public participation, the sovereignty of
data.
This document provides a unified data framework of city infrastructure governance, underpinned
by management and applications, security and privacy principles. This document is a reference for
stakeholders and provides a data framework and system structures, which help city governments,
enterprises, organizations and individuals participate in city activities and infrastructure governance.
NOTE Annex A outlines useful case studies of data framework for digital governance of infrastructure in
smart cities.

Smart community infrastructures — Data framework for
infrastructure governance based on digital technology in
smart cities
1 Scope
This document provides a framework for the application of digital technologies in smart community
infrastructures to improve the capacity of digital governance of infrastructure.
This framework is applicable to infrastructure governance in smart cities and is intended to be a basic
data framework for infrastructure governance. It can establish the basis for future standardization of
smart city infrastructures and can be further applied in other aspects of city management.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:

3.1
data framework
structure of processes and specifications designed to support the collection, transmission, organization
and use of data to applied services
3.2
digital governance of infrastructure
activity that is coordinated and implemented by a set of activities aimed to design, implement and
monitor a strategic plan for city infrastructure and its data management through, e.g. the Internet
of Things (IoT), cloud computing, mobile Internet, geospatial information, big data and other new-
generation information technologies, to realize efficient management of city infrastructure
Note 1 to entry: Governance of data is described in ISO/IEC 38505-1.
Note 2 to entry: Digital governance includes (but is not limited to) digital strategy, digital policies, digital
standards, digital processes, digital procedures, digital roles and digital control tools, put in place to meet
regulatory, legal, risk and operational requirements.
3.3
component
part of a system delimited according to structural or functional aspects, which can still implement
independent sub-functions
EXAMPLE Municipal engineering facilities, transportation facilities, amenity and environment facilities,
landscaping facilities and other facilities are component of city infrastructure.
[SOURCE: ISO 20890-4:2020, 3.10, modified — The EXAMPLE has been added.]
3.4
event
occurrence, which may have an effect on the outcome of a measurement or inspection operation and
which should be recorded
Note 1 to entry: Phenomena and behaviour caused by human or natural factors need to be dealt with by an urban
management department and restored to normal, such as components (3.3), urban appearance, environment and
environmental order, to be affected or destroyed.
[SOURCE: ISO 23952:2020, 3.4.57, modified — Note 1 to entry has been added.]
3.5
city unit grid

distribution
Note 1 to entry: City unit grid can provide basic geographical data as digital control tools for digital governance.
4 General
The data framework for digital governance of infrastructure in a smart city is made up of three parts:
application, platform and database, as illustrated in Figure 1.
Figure 1 — Scheme of data framework for digital governance of infrastructure in a smart city
As shown in Figure 1, to meet the needs of digital city management, the data framework contains the
following parts to ensure effective operation:
a) To support the data platform, databases (including geospatial databases, event databases, operation
databases and system operation support databases) are introduced. The details are described in
Clause 5.
b) To enable the digital processing of the application, the data platform is introduced and formed by
different systems to provide close-loop information management for comprehensive municipal
cases. The details are described in Clause 6.
c) As the application of the data framework, the main process of digital governance of infrastructure
in a smart city can be achieved in six steps: information collection, case filing, dispatching,
processing, feedback and checking. The details are described in Clause 7.
5 Database
5.1 Geospatial data
5.1.1 General
The geospatial database includes geospatial framework data and unit grid data and can cover the
following scope in general: administrative boundaries, geocoded addressing. positioning, place names,
land parcel and property, imagery, transport, water, elevation and depth, land cover and land use, as
well as statistical information.
5.1.2 Geospatial framework data
5.1.2.1 Classification of framework data
City geospatial framework data should cover the fields of administrative division, transportation, field
of water, construction, underground space and components. The framework data should be classified
by certain rules and should support multi-level classification and user-defined classification rules.
5.1.2.2 Description and expression of framework data
City geospatial framework data should describe the spatial features and attributes of city geospatial
elements and include the temporal characteristics of data collection or updating. Spatial features of
framework data should be described in point, line and plane features.
The attribute features of framework data should be composed of basic attributes and extended
attributes. Basic data should include a data element category code, unique identification code, data
element name, data capture date, and data s
