1 Scope
The present document specifies the requirements for an initial semantic model for the smart cities domain based on a
limited set of use cases and from available existing data models. The present document has been developed in close
collaboration with AIOTI, the H2020 Large Scale Pilots and with ETSI activities in the smart cities domain. Further
extensions are envisaged in the future to cover different aspects in the smart cities domain, for example focusing in
public equipment. The associated ETSI TS 103 410-4 [i.9] will define the ontology extension (i.e. the semantic model)
for the smart cities domain based on the requirements and use cases specified in the present document.

4 SAREF extension for the Smart City domain
SAREF [i.1] is a reference ontology for IoT created in close interaction with the industry during a study requested by
the European Commission in 2015 [i.2] and subsequently transferred into ETSI TS 103 264 [i.3]. SAREF contains core
concepts that are common to several IoT domains and, to be able to handle specific data elements for a certain domain,
dedicated extensions of SAREF can be created. Each domain can have one or more extensions, depending on the
complexity of the domain. As a reference ontology, SAREF serves as the means to connect the extensions in different
domains. The earlier document ETSI TR 103 411 [i.4] specifies the rationale and methodology used to create, publish
and maintain the SAREF extensions.
The present document specifies the requirements for an initial SAREF extension for the smart city domain based on a
limited set of use cases and from available existing data models. The present document has been developed in the
context of the STF 534 (https://portal.etsi.org/STF/STFs/STFHomePages/STF534.aspx), which was established with the
goal to create SAREF extensions for the domains of Smart Cities, Smart Industry & Manufacturing, and Smart
AgriFood. The STF 534 follows the outcomes of the earlier STF 513, which developed an updated SAREF specification
[i.3] and the first extensions of SAREF in the energy [i.5], environment [i.6] and building [i.7] domains. The STF 534
consists of the following two main tasks:
1) gather requirements, collect use cases and identify existing sources (e.g. standards, data models, ontologies,
etc.) from the domains of interest (i.e. Smart Cities, Smart Industry & Manufacturing, and Smart AgriFood);
and
2) produce extensions of SAREF for each domain based on these requirements.
The present document focuses on the extension of SAREF for the smart cities domain, which will result in a new
ontology, called SAREF4CITY, to be published in the companion ETSI TS 103 410-4 [i.9] as part of the SAREF
extensions series ETSI TS 103 410 [i.5], [i.6] and [i.7].
5 Related initiatives
In this clause, some of the main related initiatives in terms of modelling and standardization in the smart cities domain
are reviewed. Existing efforts range from national or international norms to rather specific models used in certain
software solutions. Therefore, the potential stakeholders identified for this SAREF extension might be classified as:
public administrations, associations related to the Internet of Things and Smart Cities, European projects, platforms for
IoT data processing, and standardization bodies. For each type of stakeholder, the initiatives that have been taken into
account are described next.

• Standardization bodies:
- oneM2M: oneM2M is devoted to the development of technical specifications for M2M solutions related
to the service layer which can be combined with existing hardware and software solutions. The main goal
of the organization is to attract and involve organizations in domains such as telematics and intelligent
transportation, healthcare, utilities, industrial automation, or smart homes, among others. oneM2M
prepares, approves and maintains technical specifications and reports for use cases, service layer aspects,
protocols, APIs, interoperability, data collection, and many other aspects of the M2M domain. The
oneM2M base ontology [i.10] is the minimal ontology that enables achieving interoperability among
organizations.
- OGC (Open Geospatial Consortium): The OGC is an international organization devoted to the
development of quality open standards for the global geospatial community. It includes different member
types such as governments, commercial organizations, NGOs, or academic and research organizations.
One of the standards developed by the OGC is CityGML [i.11], which consists of a model and SML-
based format for the exchange and storage of virtual 3D models. In addition, OGC provides a standard
model, GeoSPARQL, which supports the representation and querying of geospatial data based on
semantic web technologies.
- AENOR CTN 178: The Spanish Association for Standardization and Certification (AENOR, or UNE
since 2017), is a private non-profit organization founded in 1986. AENOR published in 2015 the
UNE 178301:2015 [i.12]. The norm is intended to measure the maturity level of open data projects for
smart cites, easing its development and deployment. The city-related domains considered in the norm
are: business catalogue; cultural agenda; population; air quality; contracts, public procurement, and
service providers; municipal budget and budget execution; public park loads; bus timetable, line, stops
and fares; traffic; touristic places; and city street guide.
- ISO (International Organization for Standardization): The ISO is a worldwide federation of national
standardization bodies dedicated to develop international standards through technical committees
specialized in a particular field. In 2014, ISO published the standard ISO 37120:2018 [i.13], which
establishes definitions and methodologies for indicators for city services and quality of life. This standard
allows measuring the performance of any city, municipality or local government in a comparable and
verifiable manner. In 2017, ISO in liaison with IEC (the International Electrotechnical Commission)
published the standard ISO/IEC 30182:2017 [i.14]. The Smart City Concept Model (SCCM) defines
concepts and relationships that can be used to describe data from a smart city in order to facilitate
interoperability.
• Associations:
- AIOTI: The Alliance for Internet of Things Innovation, founded by the European Commission in 2015,
consists of thirteen working groups; one of them is dedicated to Smart Cities, namely the WG08. This
group focuses on IoT solutions to enhance city performance, safety and wellbeing, cost reduction and
increase citizen engagement and active participation. The group has an interest in city-related sectors like
transport, energy, healthcare, lighting, water, and waste, among others.
- FEMP (Federación Española de Municipios y Provincias): The Spanish Federation of Municipalities
and Provinces has recently published a guide for smart city open data publication that included the
participation of around 40 representatives, from 8 different municipalities, as well as researchers and
other bodies like organizations for open data, open participation and transparency in cities. In addition,
the list of local entities supporting transparency and citizen participation includes 222 local entities from
all the Spanish geography. The city-related domains for which the FEMP proposes datasets or
vocabularies, and which extend the AENOR CTN 178 ones, are: municipal agenda; activities and events;
public park loads; warnings, suggestions and complaints; public bikes; air quality; city street guide;
census of premises, activities, terraces, restaurants and opening licenses; acoustic pollution; contracts,
public procurement, and service providers; agreements; public debt; municipal equipment; traffic; sport
equipment; touristic places; population; municipal budget and budget execution; public WiFi points and
public transport.

• IoT Platforms:
- FIWARE: FIWARE is software platform for smart cities to develop smart applications in multiple
vertical sectors. FIWARE provides data models for the following domains: alarm; environment; civic
issue tracking; device; indicator (KPI); parking; park and garden; point of interest; street lighting;
transportation; waste management; and weather.
• European projects and initiatives:
2 2
- ISA : ISA is a European programme for supporting the development of digital solutions that benefit
st
from interoperable cross-border and cross-sector public services. This programme started the 1 of
st
January 2016 and is planned to run until the 31 of December 2020. One of the solutions provided by
this programme is a set of core vocabularies which are simplified, re-usable and extensible data models
for capturing fundamental characteristics of entities. The core vocabularies developed by the time of
writing this document are: Core Person, Registered Organization, Core Location, Core Public Service,
Core Criterion and Core Evidence, Core Public Organization, and Core Public Event Vocabulary. Such
2
vocabularies are published under the Joinup initiative that is part of the ISA programme
(https://joinup.ec.europa.eu/collection/semantic-interoperability-community-semic/core-vocabularies).
The Joinup action is, more precisely, a European collaborative platform and catalogue where the core
vocabularies are hosted.
- ESPRESSO: The ESPRESSO H2020 project analysed different sectorial systems in order to develop a
conceptual Smart City Information Framework based on open standards. The project analysed the core
vocabularies for smart cities, which enable cities and stakeholders to share data in an interoperability
way in different smart city sectors.
- VICINITY: The VICINITY H2020 project will build and demonstrate a platform and ecosystem that
provides "interoperability as a service" for infrastructures in the Internet of Things. The approach is
bottom-up, decentralized, user-centric, and involving standardization without relying on a single
standard. Different smart city domains are involved in the VICINITY pilots, such as buildings, energy,
transport, and health.
6 Use cases
6.1 Use case 1: eHealth and Smart Parking
Caring of an aging population is one of the major challenges of the future of healthcare. An important step is the need to
move from institutional care to assisted-living at home, in particular for elderly people living alone and for people with
long-term needs and chronical illness (such as people with hypertension, dementia, or obesity). Electronic medical care
services enable these people to obtain a better quality and independent life.
By making use of different IoT data coming from monitoring equipment, wearables and building sensors, the goal of
the use case is, on the one hand, to provide assisted living to elderly people and people with long-term needs and, on the
other hand, to support middle-aged municipal citizens to change their everyday way of living and habits to obtain a
better quality and independent life. Actors in this use case include not only the monitored people and their close circle
(relatives, neighbours), but also health service providers (ambulances, doctors, pathologists, dietitians), assistance
services (call centres), and the same municipality.
For the case of assisted living to elderly people, the data would be collected from sensors from the building and smart
home domains, for example motion sensors, occupancy sensors, or pressure mats, among others. The collected data
would be used by added-value services to detect abnormal conditions in elderly people's daily life environment and to
trigger alarms to the municipal 24-hour call centre where specialists can provide assistance. In addition, the use case is
complemented with smart allocation of parking space when needed for municipality health services in case their
actuation is needed in a particular location, for example when a user presses the panic button.
ETSI

---------------------- Page: 9 ----------------------
10 ETSI TR 103 506 V1.1.1 (2018-09)
For the middle-aged people use case, the data would be collected from wearables (for example smart bands,
pedometers, etc.) and IoT proximity sensors that track everyday activities. The role of the municipality in this case is to
collect and process such data to create award and goal-oriented services based on individuals' needs that promote
healthy life-styles among users. In addition, specialist knowledge provided by professionals like pathologists or
dieticians could be incorporated in the use case by means of recommendations or by defining municipal-scale
campaigns to promote fitness activities to citizens.
This use case has been adapted from the Pilea-Hortiatis (Greece) pilot scenario from the H2020 VICINITY project
which deals with prevention, health promotion, mobilization and orientation in health facilities. The "Smart Parking and
Assisted Living" use case defined in AIOTI WG08 [i.8] has also been taken into account in combination with the use
case "Sharing information between parking management systems and traffic management applications" being defined in
ETSI GR CIM 002 [i.15].
6.2 Use case 2: Air Quality Monitoring and Mobility
Air pollution is a well-known problem nowadays being especially critical in larger cities such as London, Rome or
Barcelona, due to the presence of PM10 and PM25 particles. Consequently, reducing air pollution is becoming one of
the main action points in local administrations in order to meet EU directives.
Even though cities have already deployed air quality sensors, the quantity of such sensors is usually limited. In addition,
the location of such sensors might interfere in obtaining accurate air quality measurements; for example, when sensors
are located in parks that are quite distant from road traffic. In this sense, a dense network of air quality sensors would
increase the actual data from air quality allowing real-time route generation based on pollution levels. These new air
pollution sensors could be integrated in the smartphones that users are already carrying and moving over the city,
sending such data to a central monitoring and processing point. Taking this into account, one possible application is to
divert traffic over less polluted routes, therefore reducing pollution level peaks by including such an option in GPS
devices. Another possible application is avoiding high polluted roads for users exercising outside, for example running.
This could be done by integrating the real-time pollution information within mobile running applications.
This use case has been adapted from the "Air Quality Monitoring, Traffic Routing and Road Pricing" use case defined
in AIOTI WG08 [i.8] in combination with the use case "Traffic Management/Pricing based on Air Quality, Congestion,
and other KPIs" being defined in ETSI GR CIM 002 [i.15]. The use case, together with road pricing depending on
vehicle pollution levels is being investigated in on-going pilots in London and Barcelona.
6.3 Use case 3: Street Lighting, Air Quality Monitoring and
Mobility
Street lighting is a key city infrastructure for citizens as it is directly associated to the sense of security at night by them.
However, this idea of security in addition to the sense of wealth and modernity risen by lighting systems, is increasing
the light pollution levels mostly in highly populated cities like Madrid. On the one hand, both the awareness about the
light pollution consequences over citizens' health and the need for reducing costs in energy are pushing local
administrations to find solutions for a more efficient street lighting system. On the other hand, city administrations
should handle the well-known problem of air pollution suffered also by big cities due to the high concentration of
vehicles emitting CO . Finally, there is also a need for reducing pedestrian accidents due to maintenance works and
2
issues on the roads. Taking all this into account, city administrations should find a way to:
a) balance the energy spent on street lighting while keeping roads safe for pedestrians;
b) re-route traffic in order to reduce high concentrations of air pollution in specific points; and
c) provide alternative routes for pedestrians in order to avoid areas with air pollution and potential hazards due to
road works or issues.
In this use case, local administrations need to provide and deploy the infrastructure to monitor traffic and manage the
street lighting configuration. For example, there is a need for sensors to detect presence in order to redu
...
