Transcript of "Physical Mashups in the Web-Home"

  1. 1. Mashing Up Your Web-Enabled Home Enabling Physical Mashups in a Dominique Guinard, SAP Research Zurich & ETH Zurich Touch the Web 2010 @ ICWE Vienna 06.07.2010
  2. 2. [http://www.flickr.com/photos/moragcasey/] Web of Things? Physical Mashups? 1. MOTIVATION
  3. 3. Embedded Devices Invade us! • Emergence of the physical Web, everyday devices: – Getting Ubiquitous – Getting Connected
  4. 4. What if we Could Recompose Them as we Wish? • Easing the currently complicated development. • Creating a re- useable/composable physical world. • From Web mashups to physical mashups.
  5. 5. Towards Physical Mashups REST REST URL REST PHP JavaScript JavaScript [http://www.pachube.com] [http://www.webothings.com/energievisible] [http://www.clickscript.ch]
  6. 6. Contribution • Methodology for Web-enabling things. [GuiWoT10] • Discussing the requirements of physical mashups. • Introducing a Web framework supporting physical mashup editors.

  9. 9. Integrating Smart Things to the Web • Connecting them to the Internet: – Directly: IPv6 Lowpan – Indirectly: Through reverse proxies (smart gateways). • “RESTful” Things: – Functionality as resources: • BASE_URI/sunspot/sensors/light – Serving several linked representations: • HTML for browsability, • XML / JSON for integration, • ATOM for aggregation. – Using HTTP as an application protocol: • GET, POST, PUT, DELETE, [GuiWoT10] Dominique Guinard, Vlad Trifa, Erik Wilde • Error codes, Content negotiation. Architecting a Mashable Open World Wide Web of Things, Technical Report No 663, Institude for Pervasive Computing, ETH Zurich, February 2010.
  10. 10. Example: RESTful SunSPOTs • Web-enabling the Sun SPOT platform: – All sensors and actuators become resources. • Two implementation: – Web-server on the nodes. [http://www.sunspotworld.com] – Web-server on the gateway. [GuiSpot09] Dominique Guinard, Vlad Trifa, Thomas Pham, Olivier Liechti. Towards Physical Mashups in the Web of Things. Proceedings of IEEE INSS 2009
  11. 11. [http://www.flickr.com/photos/lpettinati/] Trying out physical mashups 3. CASE STUDY: CLICKSCRIPT
  12. 12. Demo Adapting a Mashup Editor • Clickscript: – Javascript (JQuery / DOJO) based visual language. • Added wrappers [http://www.clickscript.ch] for WoT devices: – RFID, SunSPOT, Ploggs.
  13. 13. [http://www.flickr.com/photos/sharynmorrow/] What do we need for physical mashups to become reality? 4. DISCUSSING REQUIREMENTS
  14. 14. Requirements for supporting Physical Mashups (1/3) • R1: Support for several UIs and modalities: – Domain specific editors (e.g. energy, security, etc.). – Beyond the desktop (e.g. mobile). – Ideally through a RESTful API. Mashup Editor Mashup API Mashup Framework Mashup Editor
  15. 15. Requirements for supporting Physical Mashups (2/3) • R2: Support for Described Things: – REST is a good start but not enough. – Describe for humans (search) and machines (discovery). – Supporting semantic service discovery: • RDF(a), Microformats, Microdata, etc. RDFa Discovery Module Mashup Framework Microformat
  16. 16. Requirements for supporting Physical Mashups (3/3) • R3: Support for Event-Based Mashups: – Many “things” are naturally event-based (e.g. sensors). – Pull for control, push for monitoring. – HTTP callbacks (Web Hooks), PuSH, etc. Editors GW Web Hook PuSH Listener Hub Mashup Framework Editors Hub Web Socket PuSH Client Server
  17. 17. [www.flickr.com/photos/docman ] Towards Supporting Real-World Mashup Editors 5. A Physical Mashup Framework
  18. 18. Concept
  19. 19. Features of the Framework Workflow Engine: • Execute the mashups (wait, –start, stop) Supports REST & WS-* things. – Supporting long running –workflows. Using on Ruote. – Discovery Component: • Things “crawler” – RDFa Descriptions – REST API: • Create mashups with HTTP. – Mashup Entry Point: • Manage the mashup lifecycle –with REST.
  20. 20. Editor on Top : Energy Mobile Mashup Editor • Energy aware mashups: – « Turn the heating off when I’m more than two KMs away from home ». • Wizard-based: – Scan tags (QR) – Setup rules – Create actions: • Physical (thing) • Virtual (e.g. xmpp, Atom, Twitter, SMS, etc.)
  21. 21. [http://www.flickr.com/photos/parmiter/] Where do we go from here? OPEN CHALLENGES
  22. 22. Challenges Towards Physical Mashups • Discovering/searching things and their services: – We use a “proprietary” RDFa description. – Standard? Currently experimenting using Microformats. • Scalability? Usefulness? – Need for qualitative/quantitative evaluation.
