RDDL, the Resource Directory Description Language, is an XML
application invented by Jonathan Borden, Tim Bray, and various other members of the
xml-dev mailing list to describe XML applications
identified by namespace URLs. A RDDL document lives at the namespace URL
for the application it describes. RDDL is a hybrid of XHTML Basic and
one custom element, rddl:resource
. A rddl:resource
element is a simple XLink that points to a resource related to the
application the RDDL document describes. Humans with browsers can read
the XHTML parts to learn about the application. Software can read the
rddl:resource elements.
