XML Resource Directory Description Language (RDDL)

This document describes the Resource Directory Description Language (RDDL). A RDDL document, called a Resource Directory, provides a package of information about some target, including:

* Human-readable descriptive material about the target.
* A directory of individual resources related to the target, each directory entry containing descriptive material and linked to the resource in question.

The targets which RDDL was designed to describe are XML Namespaces. Examples of “individual related resources” include schemas, stylesheets, and executable code designed to process markup from some namespace. A Resource Directory is designed to be suitable for service as the body of an entity returned by dereferencing a URI serving as an XML Namespace name.
