2.  Linked Data
 Web of Domotic (WoD)
 Semantic Energy Information Publishing
Framework (S.E.I.P.F).

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.  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.

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.

10.  Device Identification
 Universal Access
 Device Control
 Access to Domotic Gateway Controller
(DGC)
 Machine understandable format

11.  Universal Access Identification (UAID).
 Tags attached to the device
 QR Codes.
 [UAID].viztag.com
[UAID]
 What is viztag.com reference
domain.

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/

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.  Requirement: No network constraint.
 Assumptions:
– Access to the master DNS handling
reference domain.
– Solution: A CNAME entry aliasing UAID with
the DGC Controlling it.

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

17.  Domotics Gateway Controller
– Built on top of DOG
 Mobile Application
 Mobile Access Provider
5/3/2010 Linked Data and Domotics 17

18.  Works on behalf of user.
 Decodes QR Code.
 Extracts the UAID.
 Contacts with the DGC.

19. 5/3/2010 Linked Data and Domotics 19

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.  Energy Consumption Information
 Machine understandable format.
5/3/2010 Linked Data and Domotics 21

22.  Based on Modular approach.
 It describes the Power consumed by
different appliances in different states.
 Two basic concepts:
– DeviceProfile
– Consumption
