Well, what good is a weekend not spent coding? In this case, I managed to hack together a very rudimentary RDF parser/validator specialized for Creative Commons licenses. You can find the web interface here and the sourcecode for the CGI here. The Python module which does most of the heavy lifting, cclicense.py, will be up soon. I’d love your feedback on any or all of it.
Right now it can parse raw RDF or retrieve a URL and scan it for RDF (using a simple regular expression). In either case it parses it and spits out the licensing and work information it finds.
It still needs some work when it comes to parsing work description information, especially with sub-elements (like Agent’s). I’d also love to hear suggestions for improving the output mechanism; it currently runs as a simple CGI, so the result page’s HTML is manually emitted with print statements. Any suggestions for making this work smarter?
