A main example of a platform implementing this view is JaCaMo, which allows the programming of a MAS in terms of an organisation of cognitive agents sharing acommon artifact-based environment. However, MAS models and platforms in general do not provide a satisfactory approach for MAS developers to uniformly deal with distribution at multiple dimensions — agent, environment, and organisation. Typically, environments are either centralised in a single node, or composed by parts that run on different nodes but with a poor support atthe programming and execution levels to deal with that. In this paper, we tackle this problem by proposing a model for engineering world-wide distributed environments and organisations for MAS. The approach integrates the A&A (Agents and Artifacts) conceptual model with a web/resource-oriented view of distributed systems as proposed by the REST architectural style. To evaluate the approach, an extension of the JaCaMo open-source platform has been developed implementing the proposed model.enbook section
