# Web Services Specifications

The core XML, SOAP and WSDL standards form the basis for an extensible set of Web services specifications. Together these specifications describe a set of interoperable protocols for designing secure, reliable messaging and transactional solutions for loosely coupled, service-oriented architecture (SOA) systems.

The Gateway is designed to be platform/technology neutral to allow it to be easily incorporated into any service owner's business solution. To assist in this goal, where appropriate functionality is required, Web services specifications/standards have been adopted by the Gateway.

The XML, Metadata, Messaging and Security are briefly described in this section since they are used by the Gateway.

The following Web services specification versions are currently supported:

- Web Services Addressing: WS-Addressing (2004/03)
