WDDX (Web Distributed Data eXchange) is a programming language-, platform- and transport-neutral data interchange mechanism designed to pass data between different environments and different computers.
WDDX and XML-RPC, both created in 1998, were the precursors to SOAP and Web services. SOAP borrows the envelope/header/body structure and the transport + interaction neutrality from WDDX and the HTTP and RPC bindings from XML-RPC.
WDDX is functionally comparable to XML-RPC and WIDL. The specification supports simple data types such as number, string, boolean, etc., and complex aggregates of these in forms such as structures, arrays and recordsets (row/column data, typically coming from database queries). There are WDDX interfaces for a wide variety of languages, including ColdFusion, Ruby, Python, PHP, Java, C++, .NET, Actionscript, lisp, Haskell, Perl.
Example: (from php.net/wddx)
<wddxPacket version='1.0'> <header comment='PHP'/> <data> <struct> <var name='pi'> <number>3.1415926</number> </var> <var name='cities'> <array length='3'> <string>Austin</string> <string>Novato</string> <string>Seattle</string> </array> </var> </struct> </data> </wddxPacket>
