2. Adaptation of SFE  Systematic approach for the adaptation problem  Tasks  Sense the context  Reason about the sensed data for identifying the situation  Select the most appropriate actions  Execute them  Very different aspects to be considered  Adaptation architecture Lucio Davide SpanoA Set of Languages for Context-Aware Adaptation

12. Context Management Language  Context 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 Lucio Davide SpanoA Set of Languages for Context-Aware Adaptation

13. Conclusion  Adaptation Architecture  Different modules for managing different aspects  Design Time  Initial Application Configuration  Rule Language  Definition of the adaptation logic  Context Management Language  Different implementations of sensing delegate  Different shared managers for  Context sensing  Adaptation decisions Lucio Davide SpanoA Set of Languages for Context-Aware Adaptation
