A semantic annotation is added information in a document which describes the semantics of a part of such document. In such technical note, the semantic annotations are additional information tools in a WSDL document. They describe semantics by referring to a part of a semantic model which describes the semantics of the part of the document being annotated.

The WSDL document forms the anchor point for Web services explanation. Building on the descriptive ability of WSDL, a mechanism is given to annotate the abilities and requirements of Web services along with semantic concepts referenced by a semantic model. To do that, mechanisms are given annotate the service and its inputs, outputs and operations. Moreover, we provide mechanisms to identify and annotate preconditions and effects of Web Services. Such preconditions and effects together along with the semantic annotations of inputs and outputs can allow automation of the process of service discovery.
