CL-SOAP
CL-SOAP is a open-source (LLGPL) project hosted at http://common-lisp.net/project/cl-soap/

Ultimately, this library will implement the full SOAP 1.1 spec (http://www.w3.org/TR/2000/NOTE-SOAP-20000508), both the client and server parts, using both HTTP and HTTPS as transports as well as the WSDL 1.1 spec (http://www.w3.org/TR/2001/NOTE-wsdl-20010315) and the XML Schema Definition spec (http://www.w3.org/TR/xmlschema-1/ and http://www.w3.org/TR/xmlschema-2/) on as many CL implementations as possible. Interoperability with various other SOAP implementations and applications will be possible.

CL-SOAP was started and is currently maintained by Sven Van Caekenberghe.
