Computer science description: Klaim (Kernel Language for Agents Interaction and Mobility) is an experimental language specifically designed to program distributed systems consisting of several mobile components that interact through multiple distributed tuple spaces. Klaim primitives allow programmers to distribute and retrieve data and processes to and from the nodes of a net. Moreover, localities are first-class citizens that can be dynamically created and communicated over the network. Components, both stationary and mobile, can explicitly refer and control the spatial structures of the network. This paper reports the experiences in the design and development of Klaim. Its main purpose is to outline the theoretical foundations of the main features of Klaim and its programming model. We also present a modal logic that permits reasoning about behavioural properties of systems and various type systems that help in controlling agents movements and actions. Extensions of the language in the direction of object oriented programming are also discussed together with the description of the implementation efforts which have lead to the current prototypes. publisher: Springer contributor: Priami, Corrado date: 2003 type: Book Section type: PeerReviewed identifier: Bettini, Lorenzo and Bono, Viviana and De Nicola, Rocco and Ferrari, GianLuigi and Gorla, Daniele and Loreti, Michele and Moggi, Eugenio and Pugliese, Rosario and Tuosto, Emilio and Venneri, Betti The Klaim Project: Theory and Practice.
