Laura Daniele | SAREF and SAREF4EE: Towards interoperability for Smart Appliances in the IoT World

  1. 1. BIG DATA VARIETY AND STRUCTURE DATA SHARING IN THE IoT WORLD Laura Daniele Semantic Web Meetup: Big Data and Linked Data - the Best of Two Worlds 12 September 2016, Leipzig, Germany
  2. 2. TNO
  3. 3. TNO - THE NETHERLANDS ORGANIZATION FOR APPLIED SCIENTIFIC RESEARCH Mission: TNO connects people and knowledge to create innovations that boost the sustainable competitive strength of industry and well- being of society. ‘INNOVATION FOR LIFE’ 3
  4. 4. DATA SCIENCE DEPARTMENT: CONNECTED BUSINESS GROUP 4 Governance Semantics Infrastructure ITCMF Data quality Open standards Distributed governance for networked ontologies Governance business models Ontology matching RDF/OWL/SPARQL Linked data Semantic reasoning Federated platforms Blockchain technology Semantically rich infrastructure Scalability System of systems
  5. 5. SMART HOME
  6. 6. CURRENT SITUATION: NOT-SO-SMART-HOME… thermostat smart garage door opener smart door lock alarm system light bulbs basement flood detector security camerasmart TV motion detector smoke detector smart assistant energy meter energy manager smart wrist bands wearables smart scale dishwasher More and more devices become smart and are connected to the Internet (of Things)
  7. 7. MARKET FRAGMENTATION Companies like Apple, Google and Amazon have built up their own solutions for connecting smart home devices Apple HomeKit with Siri Amazon Echo with Alexa Nest with its own automation system Google Home with Google smart assistant Microsoft with Cortana Samsung with SmartThings 7
  8. 8. STANDARDIZATION Standards efforts and relevant actors AllSeen alliance (Qualcomm, Microsoft, LG, Sony, Electrolux, etc.) OCF - Open Connectivity Foundation, previously OIC (Intel and Samsung) AllSeen members also part of OCF (e.g., Qualcomm, Microsoft, Electrolux) AIOTI European Commission ETSI oneM2M IETF W3C Web Of Things IoT schema.org etc. 8
  9. 9. PROBLEM (1/2) Integration is now a problem of the user who should be aware of what is interoperable with what Samsung SmartThings devices controllable through Amazon’s Alexa but not Apple’s Siri Philips Hue interoperable with Nest, but other light bulbs not (e.g., Cree bulbs) do not interoperate with Nest 9
  10. 10. PROBLEM (2/2) Users should not worry about buying devices that work together, these devices should have a standard way to communicate Also, dilemma for device makers: which solution/language to support when building new devices? Need to abstract from details of specific solutions and protocols by creating an abstraction layer based on a commonly agreed semantics to enable interoperability 10
  11. 11. CHALLENGES How to harmonise this incredible fragmentation of solutions in a common open standard? Will the big players like Apple, Google, Amazon ever be interested in these common standards? Will be the offer of devices and services that emerge from a common standard be better than proprietary systems like Apple, Google, Amazon? 11
  12. 12. SOLUTION
  13. 13. THE SMART APPLIANCES PROJECT In 2013, the European Commission (EC) launched a standardization initiative to create the missing abstraction layer TNO was subsequently invited by the EC to lead the initiative and created SAREF, the Smart Appliance REFerence ontology (January 2014 - April 2015) https://w3id.org/saref https://sites.google.com/site/smartappliancesproject In November 2015, SAREF was standardized by ETSI as a Technical Specification TS 103 264 http://www.etsi.org/deliver/etsi_ts/103200_103299/103264/01.01.01_60/ts_ 103264v010101p.pdf 13
  14. 14. SAREF More details on SAREF in the next days poster at VoCarnival on Tuesday 13th at 19:00 industry talk on Wednesday 14th at 15:15 (Internet Of Things session) 14
  15. 15. CHALLENGES How to harmonise this incredible fragmentation of solutions? Open standards? Will the big players like Apple, Google, Amazon ever be interested in those common standards? Will be the offer of devices and services that emerge from a common standard be better than proprietary systems like Apple, Google, Amazon? Need to abstract from details of specific standards and protocols by creating an abstraction layer based on a commonly agreed semantics to enable interoperability 15
  16. 16. IoT schema.org INITIATIVE
  17. 17. The IoT schema.org initiative Google has recently started an initiative in which TNO is involved as developer of SAREF for the EC and member of ETSI Site: http://iot.webschemas.org Initial discussion document: http://iot.webschemas.org/docs/iot- gettingstarted.html Mailing list: https://groups.google.com/forum/#!forum/sdo-iot-sync GitHub issue: https://github.com/schemaorg/schemaorg/issues/1272 17
  18. 18. 18 ENTRY POINT FOR WORK RELATED TO IoT schema.org
  19. 19. INITIAL DISCUSSION PAPER 19
  20. 20. MAILING LIST 20
  21. 21. GitHub issue 21
  22. 22. TIMELINE Phase 1 (summer 2016): identify public mailing lists for topical discussion collection of existing works including literature reviews, mappings, collaborative prototyping and use-case driven sketching of possible designs Phase 2 (later in 2016): exploration of existing or newly proposed schemas as extensions to schema.org conversion/mapping/transformation from original data formats into something compatible with schema.org's datamodel Phase 3 (primarily during 2017): more substantive additions to schema.org core and/or population of term definitions at iot.schema.org modeling and prototyping explorations, and dialogue with relevant standards efforts such as W3C WoT 22
