Future Expectations:Spontaneous Service Interaction
Smart Web Services
Spontaneous federation of services
Dynamic personalization and customisation
Dynamic aggregation of services
Based on context: Who, what, when, where, why
Smart Web ServicesContext-Sensitive Services
Dynamic results based on Identity, security, privacy, role,
location, device, history, service level agreements...
Examples Restaurant finder Energy conservation policy Shipment policy
HurdlesInteroperability is Key No standard way to represent
Identity, roles, preferences, history, etc.
No standard way to share or propagate this context across services
No standard way to define and enforce privacy policies for this information
What We Need
Context framework: XML vocabulary for identity XML vocabulary for context Framework to access and share info
Privacy framework: Mechanism to set policies and
enforce privacy on personal/private info
