Context Management LanguageContext to be sensed in real time
Different Context Delegates provide data
Context Manager collects data from different delegates
Different operations Insert a context entity Query an entity Query all entities Update an entity Delete an entity Reset an entity Subscribe for an entity update

Rule Language Definition of the adaptation logic
Context Management Language Different implementations of sensing delegate
Different shared managers for Context sensing Adaptation decisions
