This extension is deprecated. New +implementations should use LV2 URID +instead.

This extension defines a simple mechanism for plugins to map URIs to +integers, usually for performance reasons (e.g. processing events typed by URIs +in real time). The expected use case is for plugins to 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 the +extensibility of RDF with the performance of integers (or centrally defined +enumerations).
