Definition/short description

The World Wide Web Consortium W3C defines a Web service as a software system designed to support interoperable Machine to Machine interaction over a network. Web services are frequently just Web application programming interfaces APIs that can be accessed over a network, such as the Internet, and executed on a remote system hosting the requested services.

Introductory

In common usage the term Webservice refers to clients and servers that communicate using XML messages that follow the SOAP-standard. Common in both the field and the terminology is the assumption that there is also a machine readable description of the operations supported by the server.

There are a variety of specifications associated with web services. These specifications are in varying degrees of maturity and are maintained or supported by various standards bodies and entities. Specifications may complement, overlap, and compete with each other. See more about Web service specifications in Wikipedia.
