Abstract: The collaborative systems lack descriptional support for dynamism, self-organization and collaboration. A new software architecture model named DTSArch was proposed based on decoupling of decentralized tuple space model. DTSArch provided formal semantics to describe component behavior and system configuration, dealing with the difficulty in applying decentralized tuple space model into system development A visual develop tool based on DTSArch was implemented. The practice shows that developers can quickly build system architecture on decentralized tuple space model,which improves the reusability of components and development approaches.

Key words: Decentralized tuple space, Software architecture modeling, Collaborative system
