Silly name, but a revolutionary approach to the web, and possibly a key part of the semantic web. Piggy Bank defines "screenscrapers" which web site owners can write which convert the content of their web site into an RDF data structure which the Piggy Bank FireFox plug-in can then use in order to better access the information, combine it with other sources etc etc.
The interests for me are two fold:
1) Using it as part of ReaderBot to move to a next generation agent driven access device for visually impaired users
2) Getting my Halo AI to use it to extract information
Looks like I might have to learn OWL/RDF after all.
