Different theoretical and practical insights into the field of computational organisations and electronic institutions has led to a clear separation of concerns between societal and agent-based features in the implementation of multiagent systems. From a theoretical perspective, this separation of concerns is also at the core of recent proposals towards a societal programming language. Building on the operational model of one of these proposals, this paper addresses the practical issue of implementing a web-based virtual machine for that language. The resulting framework is intended to be used in a wide range of applications, all of them related to the implementation of social processes (business processes, social networks, etc.).
