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.

+ +

This extension is intended as an improved and simpler replacement for the uri-map extension, since the +map context parameter has been found problematic.
