+<p>This extension defines a simple mechanism for plugins to map URIs to and
+from integers, usually for performance reasons (e.g. processing events typed by
+URIs in real time).  Typically, plugins map URIs to integers for things they
+"understand" at instantiation time, and store those values for use in the audio
+thread without doing any string comparison.  This allows for the extensibility
+of RDF but with the performance of integers.</p>
+
+<p>This extension is intended as an improved and simpler replacement for the <a
+href="http://lv2plug.in/ns/ext/uri-map">uri-map</a> extension, since the
+<q>map</q> context parameter has been found problematic.</p>
