WDDX: A Deeper Look

Last time we looked at the underlying reasons why Allaire created its XML-based inter-application data transmission standard called Web Distributed Data eXchange (WDDX). As I said this is a system that is designed to move data generically between different applications so they are available with their context intact.The key to this is stripping the task down to its most basic form. The reason for taking this approach is to solve the problem pragmatically without trying to provide a totalistic solution that solves all problems forever. Avoiding the "golden hammer" approach, according to Allaire's Simeon Simeonov, gets WDDX out and into the hands of developers faster so that it can be put to use quickly to solve real problems today. Eventually, when all of the ancillary services and pieces of the full XML framework are finished, approved by their respective standards bodies and consortia, Sim thinks that WDDX will be superceded by a completely XML native solution. In the meantime, though, WDDX provides a way for many developers to experiment with some of the opportunities that XML opens up without having to wait and without having to make expensive investments in new frameworks based on unfinished specifications.
