How to draw a web service using UML

Question

What's the best and most elegant way to represent a web service interface using a UML class diagram?

Solution

Well it is just a diagram to help pass a point so whatever is clear. One option is to use stereotypes put "contract" on the interface and put "web service" on the class.

This article also uses a class diagram, as well as a " solution outline ". A Sequence Diagram is not for showing structure. These approaches are all based around the very old WSDL/SOAP WS models. Modern RESTful WS APIs just use documentation to communicate the service's structure and responses.
