Description Language) Standard for describing services, inputs, outputs, other data supported by a Web service. Documents coded machine readable and used by developer tools for creating programs to access the service. SOAP Protocol for requesting Web services and for sending responses to Web (no longer an acronym) service requests. XML (eXtensible Markup Language)

Used for transmitting documents. Contains metadata to validate format and completeness of a document, includes considerable overhead (see Figure 615a). JSON (JavaScript Object Notation) Markup language used for transmitting documents. Contains little metadata. Preferred for transmitting volumes of data between servers and browsers.
