RDDL meaning in Computing ?

Answer:

What is Resource Directory Description Language mean?

In computing, Resource Directory Description Language (RDDL) is an extension of XHTML Basic 1.0. An RDDL document, called a Resource Directory, provides a package of information about some target. The targets which RDDL was designed to describe are XML namespaces. The specification for RDDL has no official standing and has not been considered nor approved by any organization (e.g., W3C).

RDDL is designed to allow both human readers and software robots to find any sort of resource associated with a particular namespace. Instead of putting one thing at the end of a namespace URI, RDDL puts a document there that lists all the machine-processable documents that might be available, including:
