摘要: Space-based computing environments are based around numerous, discrete sets of information with internal reasoning, interaction and semantics. These spaces can be treated as first-class entities thus have direct interactions between themselves spaces. We develop formalise a simple set base operations individual that preserves the integrity contained within those through larger grained semantic structures (eg: RDF molecules) historical about past interactions. then show how this forms basis extended possibleworld queries such features manifested in common scenarios.
