A tuplespace event model for mashups

Abstract

Inter-widget communication is essential for enterprise mashup applications. To implement it, current mashup platforms use the publish/subscribe pattern. However, the way publish/subscribe is used in these platforms requires a lot of manual wiring between widgets. In this paper, we propose a new Unified Widget Event Model (UWEM), which is conceptually an extension of Linda tuplespaces. UWEM separates event publishers and subscribers in space, time, and reference. Using the Keyboard-Level Model (KLM) we show that UWEM requires fewer operations to build typical mashups than conventional mashup platforms. We have implemented UWEM in a popular enterprise mashup framework, and performed an empirical study that compares UWEM with the established approach for creating mashups. The study confirms the KLM predictions, and shows that UWEM is significantly more efficient than the established approach.

“…Our framework draws a schema of the discretizer, which can be customized by applications. The discretizer divides the domain of the attribute value into several ranges or discrete ; //do nothing (23) end for (24) break; (25) . .…”

A mashup ecosystem for network management situations

“…In addition to these actions, we used, drag-and-drop a visual element → T dnd and wire two visual elements → T wire . T dnd and T wire are given by [4]: T dnd = P + 2B = 1.3s and T wire = 3P + 8B = 4.1s. Creating MVN is C est = 13M + T con38 + T rrd + 5T dnd + 4T wire .…”

“…Hereinafter, we call a network management Situation as NMSit. Information technology departments do not provide situational solutions for NMSits because the requirements of these types of Situations are usually located in the long-tail of enterprise needs [3] [4]. As result, Network Administrators must create by themselves solutions for NMSits.…”
