EPC Cloud: Simplifying the Internet of Things Thanks to Web Patterns: HTML 5 Websockets (Part 2/3)

Part 1: Cloud & REST | Part 2: HTML5 WebSockets | Part 3: Physical Mashups In a recent post, we were explaining how in a project common to MIT and ETH Zurich, we simplified deployments of IoT applications based on the EPC Global standards. We operated this simplification by applying four of the Web of Things patterns: Cloud Computing, RESTful Interface, Real-Time Web and Physical Mashups. In the first related post we described how we used Cloud Computing and RESTful Interfaces. It is now time to talk a little bit more about one of the other pattern: the Real-Time Web.

EPC Cloud: Simplifying the Internet of Things Thanks to Web Patterns: Cloud Computing & REST (Part 1/3)

Part 1: Cloud & REST | Part 2: HTML5 WebSockets | Part 3: Physical Mashups Since last summer, I had the chance to work at the MIT Laboratory for Manufacturing and Productivity (LMP) in the Auto-ID Labs sub-group, working with the lab associate director Christian Floerkemeier and Prof. Sanjay Sarma. Six month after the beginning of the project we reached a fist milestone and thought it would be good to wrap up what we did there. The idea of the project is to study how Web and Web of Things blueprints (i.e., architectural patterns) can help to foster the adoption...

Companies Making the WoT: Unboxing the New SunSpots

Over the last few years we had the chance (and increasingly have) to meet plenty of WoT researchers but also people who work for companies developing Web of Things software and products. This is the first in a series of posts where want to share with you a few companies and their people that we had the chance to visit and liked a lot.

Hackathon on social devices @ WoT2011

Because we don’t like just talking but also doing, we’ve decided to set up an exciting warm-up for our upcoming WoT2011 workshop. I named: a hackathon on social device that will take place on the 11 June 2011 somewhere in San Francisco. In 3 words (okay more than 3):

OpenPicus gets an IDE

Besides the fact that we are big Sun SPOTs fans, we also got increasingly more interested in the OpenPicus platform, not only because the constant motivation of the project founder Claudio Carnevali is impressive but mostly because the FlyPort (the OpenPicus wireless sensor node) is featuring a WiFi module and a Webserver (according to them our WoT community influenced them on that point) which makes it a nice, compliant, Web of Things device. 😉

The ‘Internet of things’ needs to be service-oriented

No breaking news in this post, but we were just informed about the fact that one of our articles was in the special selection of Service Oriented Computing of IEEE Computing now as well as Featured on ZDNet. We never really talked about this work because it largely discusses WS-* services (DPWS in particular) which are also known as “evil-services” by the RESTifarians 😀 We actually began our IoT journey with DPWS, were quite frustrated with it, but it evolved a lot since then, became an official OASIS standard, and thanks to the crew of WS4D became a lot less...

Web of Things Cook-book!

Lately we’ve been quite busy working on different book-chapters. As we finalized one of them I wanted to share it with you. This chapter is the draft version (before final edition as this is the one we are actually allowed to publish here, for the final version you should buy the book!) of a chapter the “Architecting the Internet of Things” book, edited by Mark Harrison, Florian Michahelles and Dieter Uckelmann.

RFID for the REST of us! 0

RFID for the REST of us!

In our second talk at IoT 2010 we presented a project we kept warm (and working on) for a little while now: bringing RFID to the Web. Not RFID in the sense of small RFID readers like the nice phidget reader meant for prototyping, but the world of standardized RFID networks and in particular the EPC (Electronic Product Code) Network and its EPCIS (Information Service). The Electronic Product Code Information Service (EPCIS) is a standard which defines interfaces enabling RFID events to be captured and queried. The query interface, implemented with WS-* Web services, enables business applications to consume and...

Web of Things Core Concepts Paper 3

Web of Things Core Concepts Paper

Together with Vlad and Erik Wilde, we’ve been trying since a while to write a scientific paper out of our common technical report that would sum up the founding concepts of the Web of Things. The paper finally got accepted for IoT 2010. This is a good sign because it emphasizes the fact that the Internet of Things community is now really looking into Web standards as a candidate common integration bus for the application layer of the physical world. A fact that did not really hold two years ago, when Erik’s attempt to publish a WoT paper at IoT...

Hello I’m WebKit, a Browser: Serve Me… XML Please! 0

Hello I’m WebKit, a Browser: Serve Me… XML Please!

Warning: this is an extremely technical post! But since this bug drove me nuts for a little while, I do have to expose it to the WoT community 😉 Finalizing the open-sourcing of our framework for making RFID tags part of the Web (more about that here!), I was testing it the whole day on various browsers. Firefox, fine! Opera, fine! IE, fine! Chrome, what the heck is that page!? As you might know, a resource in REST is not bound to a format (or representation as they call it). Rather, a well-done RESTful API should be able to serve...
