The imminent mass deployment of pervasive computing technologies, together with the increasing access of participatory web tools, will soon make available an incredible amount of information about the physical and social worlds and their processes. This opens up the possibility of exploiting all such information space for the provisioning of pervasive context-aware services, for facilitating users in gathering information about the world, coordinating with it, and coordinating with each other via the mediation of an information space.In this paper we present our current research work in this direction, in particular with regard to self- organized data aggregation, data representation and access middleware infrastructure. Due to the unpredictable density of such information spaces, we will also outline the continuum abstraction.
