SAREF: A NEW STANDARD FOR SMART APPLIANCES IN SMART HOMES

IOT/M2M WORKSHOP “FEATURING THE SMART WORLD”, S‐A,15‐17 NOV. 2016

EC INITIATIVE “SEMANTICS OF SMART APPLIANCES”

EC Goal: Provide the material to define the tools and data models for “smart appliances” helping EU to reach its 2020 goals on the reduction of greenhouse gas emission and buildings’ energy consumption. Next to that ultimate goal is the reduction of the cost for communication. Therefore, the development of a reference ontology was targeted as the main interoperability enabler for appliances relevant for energy efficiency.ETSI accepted to cover the communication aspect and provide the necessary standardization process support.

EXPECTED IMPACT OF SAREF

SAREF standard defines a new reference conceptual language for energy‐related applications. It will be used by devices in the home ‐ from lamps and consumer electronics to white goods like dishwashers ‐ allowing them to exchange information with any energy management system.SAREF is expected to enable demand‐response to flourish, to bring additional energy and cost savings for building owners and users, and to foster new markets. It builds on converging standardization work and on the development of platforms on which technologies and solutions will co‐exist and interact across application domains.The initiative has been welcomed by the Smart Appliance Industry, which clearly indicates the intention to adopt the SAREF ontology and its related communication framework.

EC “SEMANTICS OF SMART APPLIANCES” PROJECT

Tasks were: 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: The EC study call for the tender was in mid 2013. The link for the result is available as: https://sites.google.com/site/smartappliancesproject/deliverablesFinished on April 1st 2015 End Result: SAREF Ontology (SAREF stands for Smart Appliances REFerence)

SAREF ONTOLOGY STANDARDISATION

ETSI published SAREF standardVersion 1 in November 2015:

The standardisation work will include in its Version 2 the aligned oneM2M Mapping (through its Base Ontology to be included inoneM2M Release 2 expected in July 2016).

SAREF standardisation work contributed largely to the work and concepts of semantics and creation of the oneM2M Base Ontology.

SMART APPLIANCES COMMUNICATION FRAMEWORK STANDARDADISATION

• ETSI TS 103 267: Smart Appliances; Communication Framework was approved in November 2015.

• It complements the SAREF ontology standard with the standard for the means to communicate and share information.

• It mandates the use of oneM2M as interworking and communication framework for Smart Appliances, to ensure the ability for smart appliances to communicate in a common way, either directly or via interworking with specific local protocol.

SAREF TEST SPECS STANDARDISATION

STF 510 (Specialist Task Force) project started on 14 December 2015 under TC SmartM2M. Purpose is to develop Conformance test specifications for Smart Appliance Common Ontology mapped to oneM2M architecture. It is intended that STF 510 (as TC SmartM2M) will work closely with oneM2M WG 6 TST (Testing). Purpose is to test SAREF into the communication framework and to test the mapping to oneM2M.3 main deliverables are planned: ETSI TS 103 268‐2: PICS ‐ Conformance testing Protocol Implementation Conformance Statements ETSI TS 103 268‐3: TSS&TP ‐ Conformance testing Test Suite Structure and Test Purposes ETSI TS 103 268‐4: ATS&PIXIT ‐ Conformance testing Abstract Test Suite and Protocol Implementation eXtra Information for Testing

SAREF EXTENSION ‐1

SAREF is being expanded to cover the evolution of present requirements and also to include new requirements.The Smart Appliance industry has expressed an urgent request to extend SAREF to fill gaps of features not yet covered by the present version of specifications.The new work – being developed with the support of STF 513 referring to TC Smart M2M – addressing the extension of SAREF standard , was initially expected to take into account e.g.:

‐ Energy demand/response use cases.‐ Remarks and comments made by parties that started working with SAREF.‐ The Smart Home Device Template of HGI/oneM2M TS‐0023 (home appliances abstract informational model).‐ The mapping between the oneM2M Base Ontology (oneM2M TS‐0012) and SAREF.Additional requirements provided by interested parties to the STF 513 have been scheduled between April and September 2016.

SAREF Extension ‐2

SAREF, being the core data model for smart appliances, contains only the data elements that are used in more than one domain.As smart appliances can be used in, and come from many domains, it is possible that specific data elements for a domain are not in SAREF. To be able to handle these additional data elements extensions to SAREF can be created.Thus SAREF functions as the connection between the different domains, every domain extensions reusing the part of SAREF relevant for it. Each domain model is specified as a separate TS, thus ensuring an independent maintenance.

Outputs of STF 513 under way:

Stable draft of TR 103 411 SAP SAREF Extension Investigation ‐ which includes the requirements gathered from the main smart appliances industrial actors.

Early draft of TS 103 410 ‐1 – SAP SAREF 4ENER – extension of SAREF created in collaboration with Energy@Home and EEBus.

Early draft of TS 103 410 ‐2 – SAP SAREF 4ENVI ‐ extension of SAREF created in collaboration with Light Pollution experts of STARS 4ALL H2020 project.

Early draft of TS 103 410 ‐3 – SAP SAREF 4BLDG ‐ extension of SAREF based on the IFC standard for Building Information.

being considered as possible targets

Ontology for Health domain

Ontology for the Agriculture domain

Workshop oneM2M with SAREF Sophia Antipolis, 18 October 2016

Discussed the current alignment of SAREF to oneM2M Base Ontology being performed by STF513.

Discussed the approach taken for extending SAREF and align this with how oneM2M is looking into extending the oneM2M Base Ontology and possibly other ontologies

Agreement on the technical way of mappings between SAREF and oneM2M Base Ontology, and how this will be included in the SAREF Specification.

Way forward on ontology mapping ‐ 1

Conclusions on the way‐forward of ontology mapping, evolution and extension between oneM2M BO (Base Ontology) and SAREF.• Ontology mapping: consider to extend oneM2M

BO mapping rules to incorporate SKOS relationships

• Ontology evolution: identify the ‘common base’ of BO and SAREF, and re‐use more vocabularies from each sides as much as possible (e.g. ‘service’)

• Ontology extension: oneM2M can link with more verticals through the mapping to SAREF, which may be extended with more domain‐specific concepts.

Way forward on ontology mapping ‐ 2

A joint ad‐hoc team was formed to collaborate in the further development of the ontologies of Base Onyology and SAREF, as well as the mapping thereof.

This activity is under way.
