+<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 simplified replacement for the
+<a href="../uri-map/uri-map.html">uri-map</a> extension, since the <q>map</q>
+context parameter has been found problematic. This extension is functionally
+equivalent to the uri-map extension with a NULL context. New implementations
+are encouraged to use this extension for URI mapping.</p>
