SAREF ONTOLOGY FOR SMART
APPLIANCES: STATUS, EVOLUTION
AND TESTING
ETSI M2M Event - 10 December 2015 | Svetoslav Mihaylov (European Commission) & Jasper Roes (TNO)
CONTEXT
ETSI M2M developed functional architecture. Next step is data models. Many
are already developed by other organizations. How can they be re-used?
In 2012, EC hosted a workshop “Roadmap for the Standardization of Smart
Appliances (Energy Consuming and Producing Products)
Present: E2BA, CECED, Eu.bac, ELC, SGTF, ETSI M2M, CENELEC TC59x
WG7, HGI, buildingSmart Int., OASIS oBIX, OSGi.
Main recommendations:
High-level semantic model is needed, including common vocabulary for appliances’
product information, commands, signals, feedback.
Agree on a common architecture and open repositories with reusable pieces to
create a bridge over the communication layer chaos.
ETSI created SMART M2M TC as a follow-up on ETSI M2M
SAREF ontology for smart appliances: status, evolution and testing
THE EC “SEMANTICS OF SMART
APPLIANCES” PROJECT 1/2
Goal: Support ETSI SMART M2M as an organization. Provide the material
needed to define the relevant tools and data models for the collection of
devices that helps the EU to reach its 2020 goals regarding the reduction of
greenhouse gas emission and buildings’ energy consumption. Next to that the
ultimate goal is to drastically reduce the cost for communication.

SCOPE
Domains: Homes, private dwellings, common public buildings and offices
Appliances: Home and building sensors, white goods, HVAC, Lighting,
Micro-renewable home solutions, Multimedia and PC equipment
Use cases: Interoperability with construction design tools, facility
management systems, energy management systems, building control
systems, ESCO systems, Smart Grid
Stakeholders: manufacturers of white goods, HVAC, plumbing, security and
electrical systems, lightings, sensors, actuators, micro-renewable home
solutions, multimedia, and computers. And related industry, such as utilities,
operators, architects, service providers...
SAREF ontology for smart appliances: status, evolution and testing
THE EC “SEMANTICS OF SMART
APPLIANCES” PROJECT 2/2
Tasks:
1. Take stock of existing semantic assets and use case assets
2. Perform a translation exercise of each model or use case to a common ontology
language and subsequently a mapping between these models
3. Propose a common ontology and document it into ETSI M2M architecture
Timing: finished on April 1st 2015

END RESULT: SAREF
STANDARDS USE TO BOTTOM-UP
CREATE SAREF
SAREF ontology for smart appliances: status, evolution and testing
Smart meter
natural gas or
electricity
represents actual
measurement
like: 3456kWh or
965m3
Semantics are the definitions of the terms:
- Streetname: the name of the street the
building is located
- Town: the name of the town the building is
located in
- Productkind: the product that is measured
by the smart meter
EXAMPLE: SIMPLE ENERGY ONTOLOGY
CURRENT STATUS
ETSI standardised SAREF in November 2015:
ETSI TS 103 264 v1.1.1
TNO is working together with the Energy@Home association (Italian) and the
EEBus association (German) on an extension of SAREF to fully support their
use cases on energy demand and response. The Agora association (French)
is also supporting this activity.
SAREF is in scope within AIOTI as an example and show case of semantic
interoperability

TESTING 1/2
STF (Specialist Task Force) project starting on 14 December 2015
Managed by TC SmartM2M.
Purpose is to develop Conformance test specifications for Smart Appliance
Common Ontology mapped to oneM2M architecture.
It is intended that the STF and TC SmartM2M will work closely with oneM2M
WG TST (Testing) on this project.
Purpose is to test SAREF into the communication framework and to test the
mapping to oneM2M.

TESTING 2/2
3 main deliverables are planned
TS 103 268-2: PICS - Conformance testing Protocol Implementation
Conformance Statements
TS 103 268-3: TSS&TP - Conformance testing Test Suite Structure and
Test Purposes
TS 103 268-4: ATS&PIXIT - Conformance testing Abstract Test Suite and
Protocol Implementation eXtra Information for Testing

CONCLUSIONS
SAREF gets more and more momentum, not only on energy efficiency but
also in the IoT domain.
ETSI has standardized SAREF and is working on the maintenance
A STF will start work on testing on the 14th of December
Together with Energy@Home and EEBus TNO is working on an extension of
SAREF to fully support their use cases
