Pirating the Semantic Web with JavaScript

on YouTube ↗34m

" summary

Claims that JavaScript can read RDFa triples in-page and make license metadata actionable by the browser, demonstrated by a Chrome extension called rdfa-laser that scans for RDFa license triples, decorates images with animated lasers, and adds a small Creative Commons attribution non-commercial 2.5 indicator in the omnibar. The demo uses plain DOM/XPath access and a simple API like document.getElementsByProperty, the extension is a few dozen lines of JS (presented as ~10–15 lines) and the demo works on real sites with embedded RDFa.
