Linked Data for Ambient Intelligence

  1. 1. Faisal Razzak Politecnico di Torino, e-Lite research group http://elite.polito.it
  2. 2.  Linked Data  Web of Domotic (WoD)  Semantic Energy Information Publishing Framework (S.E.I.P.F). 5/3/2010 Linked Data and Domotics 2
  3. 3. 5/3/2010 Linked Data and Domotics 3
  4. 4.  Best practice for exposing, sharing, and connecting pieces of data, information and knowledge on the Semantic Web using URIs and RDF.  Publishing data in RDF format.  Independent of any ontological detail or inference. 5/3/2010 Linked Data and Domotics 4
  5. 5.  Use URIs as names for things  Use HTTP URIs so that people can look up those names.  When someone looks up a URI, provide useful information, using the standards (RDF)  Include links to other URIs; so that they can discover more things. 5/3/2010 Linked Data and Domotics 5
  6. 6. 5/3/2010 Linked Data and Domotics 6
  7. 7. 5/3/2010 Linked Data and Domotics 7
  8. 8.  Smart Environments + Internet of Things.  Enabling mobile users to access semantic powered information about devices and to operate them in a ubiquitous manner, independently from network-specific location dependence. 5/3/2010 Linked Data and Domotics 8
  9. 9. 5/3/2010 Linked Data and Domotics 9
  10. 10.  Device Identification  Universal Access  Device Control  Access to Domotic Gateway Controller (DGC)  Machine understandable format 5/3/2010 Linked Data and Domotics 10
  11. 11.  Universal Access Identification (UAID).  Tags attached to the device  QR Codes.  [UAID].viztag.com [UAID]  What is viztag.com reference domain. 5/3/2010 Linked Data and Domotics 11
  12. 12.  OpenID is a decentralized standard to authenticate the user.  It has the benefit that the user can chose any method or procedure to provide authentication credentials.  Based on Single Sign On (SSO).  http://myopenid.com, https://pip.verisignlabs.com/ 5/3/2010 Linked Data and Domotics 12
  13. 13.  Domotic Gateway Controller (DGC).  Provide ability to access Device Properties.  Provide ability to control Devices.  Internet enabled.  Access through a DGC URL. 5/3/2010 Linked Data and Domotics 13
  14. 14.  Requirement: No network constraint.  Assumptions: – Access to the master DNS handling reference domain. – Solution: A CNAME entry aliasing UAID with the DGC Controlling it. 5/3/2010 Linked Data and Domotics 14
  15. 15.  Xyz123 is the Device UAID.  Viztag.com is the reference domain.  http://elite.idomotics.net is the DGC URL.  Master DNS Server Entry: Xyz123.viztag.com CNAME http://elite.idomotics.net 5/3/2010 Linked Data and Domotics 15
  16. 16. RDF RDFa <rdf:Description <div about=“Simplelamp_livingroom"> rdf:about=“Simplelamp_livingroom"> <h2> Type: </h2> <div property="elite:isOf"> Lamp</div> <elite:isOf> Lamp </elite:isOf> <h2>Commands:</h2> <elite:hasCommand> <div property="elite:hasCommand"> On</elite:hasCommand> <a href="{url}">on</a> <elite:hasCommand> </div> Off</elite:hasCommand> <div property="elite:hasCommand"> </rdf:Description> <a href={url}>off</a> </div> </div> 5/3/2010 Linked Data and Domotics 16
  17. 17.  Domotics Gateway Controller – Built on top of DOG  Mobile Application  Mobile Access Provider 5/3/2010 Linked Data and Domotics 17
  18. 18.  Works on behalf of user.  Decodes QR Code.  Extracts the UAID.  Contacts with the DGC. 5/3/2010 Linked Data and Domotics 18
  19. 19. 5/3/2010 Linked Data and Domotics 19
  20. 20.  Provide ability to expose energy consumption information from the residential gateways in a machine understandable format, to achieve intelligent negotiation and consumption coordination. 5/3/2010 Linked Data and Domotics 20
  21. 21.  Energy Consumption Information  Machine understandable format. 5/3/2010 Linked Data and Domotics 21
  22. 22.  Based on Modular approach.  It describes the Power consumed by different appliances in different states.  Two basic concepts: – DeviceProfile – Consumption 5/3/2010 Linked Data and Domotics 22
  23. 23. 5/3/2010 Linked Data and Domotics 23
  24. 24. 5/3/2010 Linked Data and Domotics 24
  25. 25.  Simplified RDF  RDF with Ontological information. 5/3/2010 Linked Data and Domotics 25
