Recently, coordinationmiddleware systemshave evolved in order to describe coordination protocols in business process scenarios. This evolution proposes the use of three main components, being one of them a message broker to handle collaborative interactions among business processes. In a previous work, we proposed a framework for coordination in open BPM systems which used a centralised Linda-based implementation of amessage broker. The use of a centralised implementation leads to some common problems which a distributed model tries to solve in an efficient manner. In this paper, we present , a distributed and dynamic implementation of the message broker based on the RLinda model, which improves and extends the RLinda’s features and can be configured at runtime, being suitable formore complex and highly-dynamic business process scenarios. The performance of the proposed implementation is empirically evaluated on a cluster computing environment.

There are currently strong motivations to develop systems that can associate information with objects in video and allow users to access this information by selecting the objects in video. These systems could be used to create a new form of business applications such as consumer-driven advertising and audience-specific advertising. This paper presents the schematics for creating an object-based interactive video system and describes an authoring tool we have developed to create the interactive video. We also examine the opportunities and challenges of interactive video.
