Tuple Space for Mashups

Abstract

Inter-widget communication is essential for enterprise mashup applications. To implement it, current mashups use the publish/subscribe pattern. However, for mashup scenarios with many interactions between widgets, this pattern requires a lot of manual wiring between the widgets in existing mashup platforms. In this paper, we propose a new event model, UWEM, which is an extension of Linda and Tuple Space. UWEM separates event publishers and subscribers in space, time and reference. It provides a more flexible and effective interaction pattern among widgets. It makes it easier for users to build mashups, and also delivers a plug and play experience of building mashup application for users. We have implemented UWEM in a popular enterprise mashup framework.
