The resolution of distributed problems by applying computer systems composed by agents and organized towards a common objective is attracting the scientific community s attention. This is shown by the increasing number of initiatives for the development of methods and platforms to help constructing multiagent systems. Some platforms concentrate efforts on supporting some multi-agent systems aspects while others try to offer a complete infrastructure for the agents and organizations development. The Web Life architecture offers an implementation platform for developing Web-based multi- agent systems. The architecture is focused on the provision of a complete multi-agent infrastructure with native support for communication, coordination, decision-taking and task-oriented behavior. The incorporation of current under development standards and tools for solving specific problems in multi-agent systems is one of the main objectives of this work. These standards and tools are integrated by the Web Life framework. The architecture try to help the evolution of the Web into a Web with semantic contents that may be automatically processed - the Semantic Web.
