When the system initializes the coherence between DBs is checked Context of Use Detector Local DB AT s Information Access Device Features Detector Assistive Technologies Detector Profiles Repository User Agent Evaluation Tools developer user admin <software features/> <hardware features/> <assistive technologies/> CC/PP Profile 1 2 3 5 6 System API 2. DB entries are compared with key values in the Registry 3. Information regarding access device features is collected 4. Matches with key values and system information are put in a profile 4 5. User Agents can benefit and provide adaptive hypermedia techniques 6. Profiles are remotely stored and developers can make use of them user remote
