Simple Object Access Protocol (SOAP)
Soup is a SOAP (Simple Object Access Protocol) implementation in C.
It provides a queued asynchronous callback-based mechanism for sending
and servicing SOAP requests and a WSDL (Web Service Definition
Language) to C compiler that generates client stubs and server
skeletons for easily calling and implementing SOAP methods.
It uses the Glib main loop and is designed to work well with GTK+
applications. This enables GNOME applications to access SOAP servers
on the network in a completely asynchronous fashion, very similar to
the GTK+ programming model (a synchronous operation mode is also
supported for those who want it).
The WSDL compiler helps you make your applications interoperate with
services that expose their descriptions through WSDL.
