Solvent is a Firefox extension that helps you write screen scrapers for Piggy Bank.

Why do I need screen scrapers?

Piggy Bank needs web pages to embed information in a format that it can understand. This format is called RDF (Resource Description Framework) and its main advantage is that makes machine processing a lot easier. Unfortunately, at these very early stages, not many web pages embed or link to such "purer" RDF information, so Piggy Bank is capable to execute a particular screen scraper on particular pages in order to "extract" the information it needs.

Why do I need screen scrapers?

In short, screen scrapers allow you to turn a regular web page into a regular web page plus semantic data, and thus frees the data from the page/site that contains it.
