A Decoupled Architecture for Action-Oriented Coordination and Awareness Management in CSCL/W Frameworks

A High-Level Reference Model for Reusable Object-Level Coordination Support in Groupware Applications

“…Nevertheless, the experience of the authors working on particular aspects of the coordination reusability problem [19] indicates that this first step is very important because understanding of the overall coordination problem is crucial so as to assess the significance of partial proposals and their potential implications.…”

“…Therefore, future work includes: verifying the applicability of the model to the description of the other existing approaches to coordination support (and refining the model consequently); enhancing authors' proposals (specially [19]) according to the requirements of the model; identifying alternatives for supporting the model elements (the authors are particularly interested in the implications of the different proposals for formalizing and interpreting policies); and, exploring other coordination features, specially dynamism (the possibility of changing policies automatically depending on the collaboration context).…”

“…The identification of potential coupling points is probably one of the most interesting aspects in this sense. Actually, the authors have proposed in [19] a solution for avoiding one of the coupling points identified in the reference model: that between the application and the object-level coordination support when requesting actions and executing them (the two arrows between these two blocks shown in Figure 3). In that case the solution consisted of the application of the so-called "Command" software pattern.…”

SAGA reloaded: Towards a generic platform for developing cooperative applications

“…During the last decade, several frameworks have been developed to enable the construction of groupware applications. Examples of such frameworks are CBE [19] MetaWeb [36], Mushroom [18], Collaboration Bus [2], Habanero [4], Agilo [15], AORTA [29], DOORS [32], ANTS [21] and Artefact [3]. These frameworks are based on a centralized architecture and the major flaws of all them are the lack of interoperability support and the inability to integrate legacy applications.…”

The Opportunity of Grid Services for CSCL-Application Development

“…In the literature there are some CSCL applications proposals based on some of these standard middleware technologies ( [10] is an example). However, the specific characteristics required by CSCL makes some authors propose their own proprietary middleware [21,28] in order to ease the development of collaborative applications. ANTS [16], for instance, is built on top of the JavaBeans component model and provides additional services like a distributed event system and shared data structures.…”
