When Piggy Bank can extract "pure" information from a web page, it shows a "data coin" icon in the bottom right corner of Firefox’s status bar. Click on this icon to command Piggy Bank to collect the "pure" information.
Piggy Bank can collect “pure” information in the following cases:
- The web page has invisible link(s) to RDF data (encoded in RDF/XML or RDF/N3 formats).
- One of Piggy Bank's "screen scrapers" matches the current URL.
A screen scraper might also make use of web services to augment the information it collects from within a web page, e.g., to look up latitude and longitude of a street address.
