+
+This extension defines a simple mechanism for plugins to map URIs to and from
+integers.  This is usually used for performance reasons, for example for
+processing events with URI types in real-time audio code).  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.
+
+This extension is intended as an improved and simplified replacement for the
+[uri-map](uri-map.html) extension, since the `map` context parameter there has
+proven 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.
