WDDX (Web Distributed Data eXchange) is a programming-language-, platform- and transport-neutral data interchange mechanism to pass data between different environments and different computers. It 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. ColdFusion, Ruby, Python, PHP, Java, C++, .NET, Actionscript, lisp, Haskell, Perl and various platforms support it very well.
