At its core, Dapper allows users to create API?s called ?Dapps? by selecting data from Websites, RSS/XML feeds, Google Gadgets, and more. Each ?Dapp? is an XML which can be manipulated in any number of ways. The company released a tool to create Netvibes modules in late 2006.
Dapper?s Facebook AppMaker lets these Dapps be transformed into full-blown Facebook applications. This includes functionalities such as remote search and retrieval, remote login, and multi-page apps. A Facebook Developer account is a prerequisite to the AppMaker process itself.
