SOAP::WSDL::Manual::Glossary - Those acronyms and stuff
Web services are RPC (Remote Procedure Call) interfaces accessible via some
internet protocol, typically via HTTP(S).
SOAP is (was - since 1.2 the name "SOAP" has no meaning any more) an
acronym for Simple Object Access Protocol. SOAP is a W3C recommendation. The
latest version of the SOAP specification may be found at
SOAP defines a protocoll for message exchange between applications. The most
popular usage is to use SOAP for remote procedure calls (RPC).
While one of the constituting aspects of a web service is its reachability via
some internet protocol, you might as well define SOAP services accessible via
Despite it's former name, SOAP has nothing more to do with objects than cars
have with pets - SOAP messages may, but not necessarily do carry objects, very
much like your car may, but does not need to carry your pet.
WSDL is an acronym for Web Services Description Language. WSDL is a W3C
recommendation. The latest version of the WSDL specification may be found at
WSDL defines a XML-based language for describing web service interfaces,
including SOAP interfaces.
WS-I (Web Services Interoperability Organization) is an open industry
organisation chartered to promote Web service interoperability across
platforms, operating systems, and programming languages.
WS-I publishes profiles, which provide implementation guidelines for how related
Web services specifications should be used together for best interoperability.
To date, WS-I has finalized the Basic Profile, Attachments Profile and Simple
SOAP Binding Profile.
SOAP::WSDL aims at complying to the WS-I Basic Profile (but does not implement
full support yet).
Meant for transporting a RPC message. All contents of the SOAP body are put into
a top-level node named equal to the SOAP operation.
WS-I Basic Profile allows the use of rpc message style.
SOAP::WSDL does not support rpc message style yet.
SOAP::Lite supports rpc message style only.
Meant for transporting arbitrary content. No additional nodes are inserted
between the SOAP body and the actual content.
WS-I Basic Profile allows the use of document message style.
