Here's the first native C RDFa implementation in a web browser that I
know of:


Fuzzbot is a native Firefox plug-in using librdfa for the back-end
processing. The HTML/XHTML document is retrieved using Firefox,
serialized to XML using Javascript, passed to librdfa via XPCOM, which
generates triples. The triples are "streamed" to the Javascript engine
using a C++ to Javascript XPCOM callback and finally displayed in the
Firefox UI:


You can get the 50KB plug-in (which includes the librdfa parser, XPCOM
components, all javascript and images) for Linux from here:


Code can be retrieved via git:

git clone http://rdfa.digitalbazaar.com/fuzzbot.git


- This is VERY preliminary - only 3 days of development have gone into
it - bugs abound - use at your own risk.
- The UI is atrocious.
- Windows/Mac OS X support is planned.


1. Install the plug-in if you have Linux.
2. Click on the Fuzzbot icon (little gray sphere) in the status bar to
view any RDFa triples in the page.


- The system can only handle around 375 triples per second (roughly 1MB
of XHTML per second) at the moment due to a weird memory allocation bug.
- The Creative Commons Attribution-Share-Alike 3.0 license page locks
the parser and consequently, the browser :P.
