Well, not quite, but the application does seem very interesting and worth playing around with a bit (Piggy Bank). From the introduction:

Piggy Bank is an extension to the Firefox web browser that extracts information from existing web pages and stores it in RDF. If a web page already links to RDF information, extraction simply means retrieving that information. Otherwise, Piggy Bank employs custom software code that untangles the “pure” information from the web page’ formatting.

Having extracted the “pure” information and stored it on your computer, Piggy Bank can now apply its own user interface to let you browse through that information independent of the original web sites. For example, Piggy Bank can call upon Google Maps to display geographical information even if the original web sites do not offer cartographic views of their data.

Furthermore, by storing “pure” information from different web sites in the same data model, Piggy Bank can offer a unified view on the “pure” information regardless of its many origins.

The piece of software code that Piggy Bank uses to “purify” information within a web page is called a screen scraper. Different screen scrapers are made for different web pages. Piggy Bank supports an easy way to install screen scrapers, so that getting better use of a web page’s information is just a few clicks away.
