“…DreamTeam (Roth, 2000a) uses the HALF-SYNC/HALF-ASYNC pattern by providing a 'connection manager' responsible for synchronous communication and a 'transfer manager' that takes care of large asynchronous transfer of data.

“…Of all these development aids, the only one that has advanced remarkably in the domain of collaborative applications is application frameworks. There are several frameworks in the market that offer reuse of design and code, for example Agilo (Guicking, 2005), Clock (Graham et al, 1996;Urnes and Graham, 1999), COAST (Schuckmann et al, 1996), Dream-Objects (Lukosch, 2003), DreamTeam (Roth, 2000a), GroupKit , Rendezvous (Hill et al, 1994), Suite (Dewan and Choudhary, 1995) and TCD (Anderson et al, 2000). But the shortcoming of these frameworks is that they are characterised by limited scalability, extensibility and customisability.…”

Abstract:There is currently little reuse of either design or code in the development of collaborative applications. Though there are some application frameworks for this domain, they tend to be rather inflexible in the functionality they offer. This paper seeks to provide design reuse in the form of architectural patterns that focus on low-level horizontal issues: distribution, message exchange, functional decomposition, sharing data, concurrency and synchronisation. We base these patterns on a number of well-established patterns in the domain of distributed applications, concentrating on the specific issues that are encountered in the domain of collaborative applications. We also outline the relation between these low-level architectural patterns and the high-level functionality that collaborative applications offer. By codifying this knowledge and experience in the form of patterns, we hope for a wider support of low-level architectural design to the community of collaborative applications and thus a further advance of the field.

Abstract. In a collaborative session users may join and leave. A user who joins a session is called a latecomer. A latecomer needs the current state of the collaborative session to participate in the session. There exist different approaches to accommodate a latecomer. The runtime system can, e.g., transfer the state to the latecomer or replay how the session state was reached. If the state is maintained on a well-known server, it is quite simple to supply the latecomer with the current state. However, if the server is not available, the latecomer cannot join. To increase the fault-tolerance, the runtime system has to use a decentralized approach. In this case, race conditions must be taken into account. DreamObjects is a platform that simplifies the development of shared data objects. It supports a direct state transfer as well as a replay and lets a latecomer choose how to join a session. Both approaches are completely integrated in the runtime system, work completely decentralized, and do not block the other participants in their current work.

Abstract. Today there exist many frameworks for the development of synchronous groupware applications. Although the domain of these applications is very heterogeneous, existing frameworks provide only limited flexibility to integrate diverse groupware applications in a meaningful way. We identify five variation points that a groupware framework needs to offer in a flexible way in order to facilitate the integration of diverse groupware applications. Based on these variation points, we propose a groupware framework called Agilo that tries to overcome the limited flexibility of existing frameworks by offering multiple realizations of these variation points and providing a modular architecture to simplify the integration of applications and the extensibility and adaptability to different application and integration requirements.
