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 simplified replacement for the +uri-map extension, since the +map context parameter has been found problematic. New implementations +are strongly encouraged to use this extension for URI mapping.

+""" . + +urid:map + a lv2:Feature ; + lv2:documentation """ +

A feature which is used to map URIs to integers. To support this feature, +the host must pass an LV2_Feature to LV2_Descriptor::instantiate() with URI +LV2_URID_MAP_URI and data pointed to an instance of LV2_URID_Map.

+""" . + +urid:unmap + a lv2:Feature ; + lv2:documentation """ +

A feature which is used to unmap URIs previously mapped to integers by +urid:map. To support this feature, the host must pass an LV2_Feature to +LV2_Descriptor::instantiate() with URI LV2_URID_UNMAP_URI and data pointed to +an instance of LV2_URID_Unmap.
