“…More flexibility is achieved with significantly less programming efforts. Roussev et al, (2000) resembles our work in that it also takes a component-based approach and separates data and control. The shared state of a data component is modeled as JavaBean properties and state changes as property change events.…”

“…Our implementation follows the established component-based software engineering practices, e.g., (Graham et al, 1996;Roussev et al, 2000;Hummes and Merialdo, 2000;Litiu and Prakash, 2000;Emmerich, 2002;Grundy and Hosking, 2002;Szyperski, 2002). Adaptable consistency control entails a componentized design of data, protocols, and the ''gluing'' code that facilitates the interaction between data and protocols at run time.…”

Consistency control is a critical issue in collaborative systems. Supporting flexible consistency control in particular matches the dynamic and situated needs of cooperative work. However, previous approaches generally provide only limited flexibility due to their static binding between shared data objects and consistency control protocols. We propose a component-based framework that allows for the runtime plug-n-play of consistency protocols in collaborative systems. We model data and protocols in a way such that they are cleanly separated and can be dynamically bound at run time to achieve flexible control. Data-protocol bindings can happen at the property, object, and workspace levels. The framework provides reusable services for implementing adaptable consistency control in a range of collaborative workspace applications.

“…Flexible CSCW toolkits differ in the functionality they target and therefore in the kinds of application aspects that they facilitate. As an example of this variety, consider: Prospero [7,6] which concentrates on distributed data management and consistency control mechanisms; Intermezzo [8] focus on the coordination aspects of collaboration, in support of fluid interactions, offering user awareness, session management, and policy control; GroupKit [23] offers a basic infrastructure that includes distributed process coordination, groupware widgets and session management; Roussev, Dewan and Jain [24] propose a component-based approach based on extensions to JavaBeans, and focus on the reuse of existing single user application code, that is converted for multi-user with minimum code changes.…”

Abstract. The Neem Platform is a research test bed for Project Neem, concerned with the development of socially and culturally aware group systems. The Neem Platform is a generic framework for the development of augmented collaborative applications, mainly targeting synchronous distributed collaboration over the internet. It supports rapid prototyping, as well as Wizard of Oz experiments to ease development and evolution of such applications. A novelty of the work is its focus on the dynamic aspects that distinguish group interaction under a Perceptual interface paradigm. Participants' multimodal interactions such as voice exchanges, textual messages, widget operations and eventually gestures, eye gaze and facial expressions are made available to applications, that apply situated reasoning, using this rich contextual information to dynamically adapt their behavior. The system presents itself multimodally as well, through a set of virtual participants -automated entities that are perceived by human participants as having personalities and emotions, making use of animation and voice generation.

This paper deals with the behavior of virtual environments from the collaboration point-of-view, in which actors (human or virtual beings) interact and collaborate by means of interdependent tasks. In this sense, actors may realize tasks that are dependent on tasks performed by other actors, while the interdependencies between tasks (through resource management and temporal relations) delineate the overall behavior of a virtual environment. Our main goal is to propose an approach for the coordination of those behaviors. Initially a generic study of possible interdependencies between collaborative tasks is presented, followed by the formal modeling (using Petri Nets) of coordination mechanisms for those dependencies. In order to implement such mechanisms, an architecture of reusable and pluggable coordination components is also introduced. These components are used in an implementation of a multi-user videogame. The presented approach is a concrete step to create virtual societies of actors that collaborate to reach common goals without the risk of getting involved in conflicting or repetitive tasks. r
