A service description is an information artifact containing not only a description of the service interfaces. It defines the message formats, datatypes, transport protocols, and transport serialization formats that should be used between the requester agent and the provider agent. It also specifies one or more network locations at which a provider agent can be invoked, and may provide some information about the message exchange pattern that is expected. In essence, the service description represents an agreement governing the mechanics of interacting with that service. [W3C] __ALT__

A Service Description allows the users to access a service regardless of where and whom it is actually offered. It specifies all the information needed to the potential consumers to access and use the service. [PO-JRA-1.1.1] __ALT__

The Service Description is provided by the service provider during the service publication, and it’s used by the service consumer to choose the correct service during the service discovery. [CD-JRA-1.1.2]
