Piggy Bank is an extension to the Firefox web browser that turns it into a “Semantic Web browser”, letting you make use of existing information on the Web in more useful and flexible ways

  • Piggy Bank can help you to combine information from several web sites and browse it all together
  • Browse and search through an existing web site in better ways than the site allows you to.
  • Save information you have found on the Web, not as bookmarks but as full “database” records that can later be sorted and searched by any attribute they carry.
  • Tag each item you save with several relevant keywords rather than filing it into one single bookmark folder.
  • Share the information you have saved by publishing it onto a Semantic Bank with just one mouse-click.

There is good documentations and publications for both users and developers in Piggy Bank website. You can download the extension from here (Java Required).
