XML in itself is not sufficient it is too arbitrary in that you can code it in many ways to describe the same piece of data. The W3C family of specifications collectively known as the Resource Description Framework (RDF) serves this purpose of providing methodologies to establish syntactic structures that describe data. SOAP messages are typically conveyed over HTTP transport, although other transports (such as JMS or e-mail) are equally viable.

SOAP APIs for Web services are described by WSDL documents, which themselves describe what operations a service exposes, the format for the messages that it accepts (using XML Schema), and how to address it. The SOAP message body encapsulates the application-specific payload. The header is used to exchange contextual information that is not specific to the application payload (the body), such as authentication information. The first is the use of an XML message format for platform-agnostic encoding, and the second is the message structure, which consists of a header and a body. There are two key components of the SOAP specification. Originally an acronym for Simple Object Access Protocol, SOAP has been re-termed Services-Oriented Access Protocol (or just SOAP) because its focus has shifted from object-based systems towards the interoperability of message exchange. SOAP is a fundamental technology of the Web Services paradigm. The Google Maps API is intended for access through browser-side JavaScript, and is an example of client-side technology. However, many interesting potential, the next generation of services available on the World Wide Web.) The benefits of client-side mashing include less overhead on behalf of the mashup server (data can be retrieved directly from the content provider) and a more seamless user-experience (pages can request updates for portions of their content without having to refresh the entire page). To facilitate data retrieval, providers often expose their content through Web-protocols such as REST, Web Services, and RSS/Atom (described below). In the mashup example, the providers are Google and the Chicago Police Department.

These are the (sometimes unwitting) providers of the content being mashed. A mashup application is architecturally comprised of three different participants that are logically and physically disjoint (they are likely separated by both network and organizational boundaries): API/content providers, the mashup site, and the client's Web browser.
