<p><b>New page</b></p><div>'''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 namespace]]s. The specification for RDDL has no official standing and has not been considered nor approved by any organization (e.g., W3C).<br />
<br />
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 [[Uniform Resource Identifier|URI]], RDDL puts a document there that lists all the machine-processable documents that might be available, including:<br />
<br />
* [[Document Type Definition]]s (DTD)<br />
* [[XML schema]]s in a variety of languages (including [[Regular Language description for XML|RELAX]], [[Schematron]], [[W3C XML Schema]], [[Regular Language description for XML|TREX]], and others)<br />
* [[Cascading Style Sheets]], [[XSLT]], and other style sheet specifications<br />
* Specification documents<br />

An RDDL document identifies each related resource by a resource element in the http://www.rddl.org/ namespace, which is customarily mapped to the rddl prefix. This element is a simple [[XLink]] (that is, it has an <code>xlink:type</code> attribute with the value simple) and its <code>xlink:href</code> attribute points to the related resource. Furthermore, the <code>xlink:role</code> attribute identifies the nature of the related resource and the optional <code>xlink:arcrole</code> attribute identifies the purpose of the related resource. An optional <code>xlink:title</code> attribute can provide a brief description of the purpose of the link.<br />
