A multiagent system is no more than a collection of interacting autonomous agents. However, this interaction allows the system as a whole to perform tasks beyond the reach of its individual members. This clearly accounts for the boost in research geared towards profitting from this interaction. Accordingly, this paper addresses the formal modeling of a common kind of interaction known as delibe...

Extending and reinterpreting earlier work on the 'Spatial Model', this paper presents a generic model for supporting awareness in cooperative systems ('the AETHER model') and an implementation of a prototype awareness engine. The applicability of the approach is investigated by showing how some of the fundamental functionality in CSCW applications (e.g. versioning and access control) can be sup...
