Characteristic Requirement Short description
Discoverable Imperative
A service has to expose its functionality, supported
protocols and attributes, in order to be discovered.
Composable Imperative
A pervasive service has to be able to cooperate with
other services by implementing the relevant
Daidalos PSP interfaces.
Context-aware Optional A service may be context aware.
Personalisable Optional
A pervasive service may be aware of the user’s
personal preferences, i.e. it may have parameters
that can be personalised.
Private and Secure Optional
A pervasive service may specify privacy and
security requirements when accessing sensitive
user-related data.
