Resource Directory Description Language

<p>In <a href="/facts/Computing/Kghtm9fX">computing</a>, Resource Directory Description Language (RDDL) is an extension of <a href="/facts/XHTML/6qHnmJSg">XHTML</a> 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 <a href="/facts/XML_namespace/vRXPlXVn">XML namespaces</a>. The specification for RDDL has no official standing and has not been considered nor approved by any organization (e.g., W3C).
</p><p>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 <a href="/facts/Uniform_Resource_Identifier/UjyqxTpA">URI</a>, RDDL puts a document there that lists all the machine-processable documents that might be available, including:
</p>
<ul><li><a href="/facts/Document_Type_Definition/JsvY9PyQ">Document Type Definitions</a> (DTD)</li>
<li><a href="/facts/XML_schema/uWam66Rj">XML schemas</a> in a variety of languages (including <a href="/facts/Regular_Language_description_for_XML/DtflueRu">RELAX</a>, <a href="/facts/Schematron/3GAKjQHG">Schematron</a>, <a href="/facts/W3C_XML_Schema/X6Uly3dm">W3C XML Schema</a>, <a href="/facts/Regular_Language_description_for_XML/DtflueRu">TREX</a>, and others)</li>
<li><a href="/facts/Cascading_Style_Sheets/tA90XBQo">Cascading Style Sheets</a>, <a href="/facts/XSLT/0gw4WVyJ">XSLT</a>, and other style sheet specifications</li>
<li>Specification documents</li></ul>
