When I
was a young French teacher, I used to put big signs on all the objects
in our classroom (which was actually an old farmhouse) with their
French names—la table, le cahier, la chaise, le mur, la peinture, le
chat (the cat didn’t like it very much!). I was reminded of this
practice when I stumbled upon a similar real-world tagging phenomenon
that is cropping up in odd places around the world. It’s a form of
mobile tagging, using Semapedia and QR Codes.
Semapedia is a research site that lets people create two-dimensional
bar codes for physical objects, paste a label with the code on the
objects, and link those objects to a Wikipedia
article. QR codes (which stands for Quick Response) are the specific 2D
bar codes that people seem to have gravitated towards. A QR Code is a
matrix code created by Japanese corporation Denso-Wave in 1994. While
the patent is held by Denso-Wave, the company encourages broad usage.
QR codes were originally used in Japan for tracking automobile parts.
But they soon began to be used by advertisers who placed them on
posters and products in order to provide a quick link to a specific
promotion via customers’ mobile phones.
Citizen-Tagging for Fun and Edification
Now, all over the world, people are pasting labels with 2-dimensional bar codes on them onto buildings and objects of all kinds. The purpose of these tags is to provide a link to a relevant Wikipedia article. It’s a citizen-led, guerrilla approach to linking objects in the physical world to useful context and information in the virtual world.
These tags are turning up on stores, museums, paintings, ATM machines, bridges, street corners, parks, records, books, and other types of merchandise. (I found a tag on a carton of San Pelligrino bottled water and another tag on a shelf with Perrier.) If you have a mobile phone with the right software installed, you can point your phone’s camera at the bar code, and the code will be converted into a mobile-URL link to the Wikipedia article about that object. If you take a photograph of the object and upload it to Flickr and add your geographic coordinates, it will also appear on a map which is maintained at Semapedia.org.
From Advertiser Push to Consumer Pull
What I love about this Semapedia grass roots movement is that it takes a technology that is being used to push ads and promotions out to consumers and turns it around so that consumers are selecting the things they care about to tag and creating the links as well as the Wikipedia articles to go with them. If you take a look at the tags that have been created, as well as the photos that have appeared on maps, you can see these flurries of customer activity in different countries as people discover Semapedia and begin to tag things they encounter. Some of the tags are created by traveling digirati and bloggers as they move around the world. Others seem to be created by locals.
How Can You Participate?
You can participate by creating and posting your own QR codes on items of interest in your neighborhood and ensuring that there’s a relevant and germane Wikipedia entry. Usually you start by finding a relevant Wikipedia article (and/or creating one), then you can enter that URL into this form and print it out on label paper (or regular paper and use tape to attach it). If you see a QR code and want to follow the link, you’ll need to download the appropriate QR Reader into your cell phone or PDA (which also needs a camera and an Internet browser). You can find the downloads for many mobile phones at the bottom of this same Web page.
Very nice review! We also did some other physical hyperlinking projects:

QR was used last year in London to advertise the movie Sunshine via a billboard-size poster in one of the geekier areas of town.

Hi there,
Semapedia is really nice to share already existing content about places and objects. But you can also generate mobile tags for your 'private' use (if you want to share your blog, music, vCard, pictures, social network profile etc) at www.Snappr.net.
You can create Codes and print them on shirts, caps and other apparel. If you don't like the content of your Code anymore, just change it on the website as it dynamically determined, based on your settings. The Codes are easily created and can be read by all QR Code readers that allow opening URLs (which are ALL of them :) ).
Cheers,
Philip
