Automation of service use by agents |
|
Ideal: discovery, selection & use of a
service never before encountered |
|
Enable reasoning/planning about services |
|
e.g., Composition and Decomposition |
|
Integrated use with information resources |
|
Ease of use; powerful tools |

|
Associated with each service is a set of inputs,
outputs, preconditions and effects |
