“…Agents in Linda communicate by putting tuples in, and removing them from a shared space, i.e., the tuplespace. Throughout the years, variants for distributed computing appeared, such as Sun's JavaSpaces [28], TuCSoN [55], MARS [12], and LIME [46].…”

The current practice in multiagent systems typically associates the environment with resources that are external to agents and their communication infrastructure. Advanced uses of the environment include infrastructures for indirect coordination, such as digital pheromones, or support for governed interaction in electronic institutions. Yet, in general, the notion of environment is not well defined. Functionalities of the environment are often dealt with implicitly or in an ad hoc manner. This is not only poor engineering practice, it also hinders engineers to exploit the full potential of the environment in multiagent systems.In this paper, we put forward the environment as an explicit part of multiagent systems. We give a definition stating that the environment in a multiagent system is a first-class abstraction with dual roles: (1) the environment provides the surrounding conditions for agents to exist, which implies that the environment is an essential part of every multiagent system, and (2) the environment provides an exploitable design abstraction for building multiagent system applications. We discuss the responsibilities of such an environment in multiagent systems and we present a reference model for the environment that can serve as a basis for environment engineering. To illustrate the power of the environment as a design abstraction, we show how the environment is successfully exploited in a real world application. Considering the environment as a first-class abstraction in multiagent systems opens up new horizons for research and development in multiagent systems.

“…They have advantages over the standard client-server model in cases of concurrent processing of published information from heterogeneous sources. This has been successfully demonstrated by a wide range of space-based systems applied to solve communication and coordination issues in areas such as open distributed systems, workflow execution, XML middleware and self-organization (Ciancarini et al, 1996;Cabri et al, 2000;Ciancarini et al, 2003). All of these areas are relevant to Web-based, and implicitly to Semantic Web-based, systems.…”

Semantic technologies promise to solve many challenging problems of the present Web applications. As they achieve a feasible level of maturity, they become increasingly accepted in various business settings at enterprise level. By contrast, their usability in open environments such as the Webwith respect to issues such as scalability, dynamism and openness-still requires additional investigation. In particular, Semantic Web services have inherited the Web service communication model, which is primarily based on synchronous message exchange technology such as remote procedure call (RPC), thus being incompatible with the REST (REpresentational State Transfer) architectural model of the Web. Recent advances in the field of middleware propose 'semantic tuplespace computing' as an instrument for coping with this situation. Arguing that truly Webcompliant Web service communication should be based, analogously to the conventional Web, on shared access to persistently published data instead of message passing, space-based middleware introduces a coordination infrastructure by means of which services can exchange information in a time-and reference-decoupled manner. In this article, we introduce the most important approaches in this newly emerging field. Our objective is to analyze and compare the solutions proposed so far, thus giving an account of the current state-of-the-art, and identifying new directions of research and development.

“…Our approach relates to the idea of engineering the coordination space of a distributed system by some policy "inside" the tuple spaces, following e.g. the pioneer work of programmable tuple spaces like TuCSoN [22] or Mars [9]-and subsequent coordination frameworks such as those of coordination artifacts [20,19]. Though our coordination activities can be mapped to a certain extent on top of those fully-expressive programming models, we believe they are different in spirit in at least two ways: first, we foster the idea that agents inject the desired behaviour (which is not to be seen as a program for the space), and second, we push forward the idea of space-time computations which the above works typically neglect.…”

Abstract. We present a vision of distributed system coordination as a set of activities affecting the space-time fabric of interaction events. In the tuple space setting that we consider, coordination amounts to control of the spatial and temporal configuration of tuples spread across the network, which in turn drives the behaviour of situated agents. We therefore draw on prior work in spatial computing and distributed systems coordination, to define a new coordination language that adds to the basic Linda primitives a small set of space-time constructs for linking coordination processes with their environment. We show how this framework supports the global-level emergence of adaptive coordination policies, applying it to two example cases: crowd steering in a pervasive computing scenario and a gradient-based implementation of Linda primitives for mobile ad-hoc networks.
