Whip: A framework for mashup development with block-based development approach

The emerging of Web 2.0 and Web 3.0 technologies allows web users not only authoring and customizing web pages and their content but also integrating the contents of several web sites into one web page. This web integration is called web mashup. There are various End Users Programming development approaches in making mashup such as scripting, dataflow, widget, spreadsheet, and Programming By Demonstration (PBD). Whip design, as a tool lets casual users - those without programming skill - do the mashup easily through Block-Based Programming (BBP) approach. The design of Whip is guided by a number of principles that support this goal; ranging from situational application, user´s preference, User´s skill level to code sharing. In this paper we expound the philosophy of Whip design and explain how the design of Whip supports those principles.
