This paper describes an application framework for providing and managing personalized, interactive video on the web. The application framework enables content providers and aggregators to stream personalized content to end-users. The server stores video and multimedia content that is structured and profiled. The content profile is matched against an end-user's interest profile to determine which parts of the video to include and what hotspots and hyperlinks to provide to the user. The server generates SMIL files that represent the personalized content and returns their unique URLs to the client when responding to end-user requests.This paper also describes how the application framework is implemented by the HotStreams system. HotStreams is implemented using the Java 2 Enterprise Edition (J2EE). HotStreams is eCommerce and micropayment enabled and provides the means for content providers to specify the value of the content down to the level of individual video clips. This allows the content provider to charge for the parts of the video that the end-user actually viewed or received.The HotStreams application includes web-based management tools that enable content managers to manage multimedia objects, to compose, structure, and profile the content, to create and profile hotspots and hyperlinks, and to manage pricing information and advertisements. The management tools are implemented in the form of Java applets that run inside a web browser.

Global software engineering (GSE) courses traditionally require cooperation between at least two universities so as to provide a distributed development environment to the students. In this study, we explore an alternative way to organize a global software engineering course where students work on open source software development (OSSD) projects rather than in a multi-university collaboration setting. The results show that the new setup may provide core GSE challenges as well as challenges associated with software development outsourcing and challenges related to working on large open source software. The present article compares the experiences gained from running a combined GSE and OSSD course against the experiences gained from running a traditional GSE course. The two alternatives are compared in terms of students' learning outcomes and course organization. The authors found that a combined GSE and OSSD course provides learning opportunities that are partly overlapping with, and partly complementary to, a traditional GSE course. The authors also found that the combined OSSD and GSE course was somewhat easier to organize because most of the activities took place in a single university setting. The authors used the extended GSE taxonomy for the comparison and found it to be a useful tool for this, although it had some limitations in expressive power. Therefore, two additional relationship dimensions are proposed that will further enrich the extended taxonomy in classifying GSE (and OSSD) projects.
