Web Services: agents and roles
- The provider entity and the requester
entity:
- interact exchanging messages
- must first agree on both the semantics and the
mechanics of the message exchange
- the mechanics of the message exchange are documented
in a Web service description (WSD), a machine-processable
specification of the Web service's interface representing a
"contract" governing the mechanics of interacting with a
particular service
- the semantics of the message exchange represents the
"contract" between the requester entity and the provider entity
regarding the purpose and consequences of the
interaction
- Humans still play a role:
- need to agree on the semantics and the service
description
- create the requester and provider agents
