This Ruby extension implements a DataMatrix encoder for Ruby. It is typically used to create semacodes, which are barcodes, that contain URLs. This encoder does not create image files or visual representations of the semacode. This is because it can be used for more than creating images, such as rendering semacodes to HTML, SVG, PDF or even stored in a database or file for later use. Once you have a visual representation of the semacode, you can use a reader, such as those from http://semacode.org on your camera phone, to capture the URL embedded in the semacode and proceed directly to that web site. You need a mobile camera phone supported by or listed in http://semacode.org/about/hardware/ The software is available via ruby gems (gem install semacode) and you can find source at http://rubyforge.org/projects/semacode/ To find out more, please view the README at http://rubyforge.org/docman/view.php/3201/705/readme.html -- G.

Very cool! These are the bar codes of the future, since they can store data, sort of like a yaml file. They're already widely in use here in Japan, but not yet in the US.
