WOS communities - interactions and relations between entities in distributed system

We describe the interaction and relation between entities in distributed systems, as proposed in the Web Operating System (WOS). Every entity in the system is a versioned object which depends on its current context, which itself is programmable and can be effected by the objects circulating within it. These entities interact through mechanisms of requests/answers and negotiations. Those who exhibit functional and behavioral affinities may dynamically associate themselves to form communities. This positional paper states the basic ideas of the notion of communities in distributed systems.
