It only sets up a relation UniqueID -> paths
i just took some code from jack-rack and showtaxonomy.c

This is essentially what has to be done:
i can send the complete file if this is not sufficient for
you....



PRIVATE void setup_lrdf( void ) {


 lrdf_init( );
 plugin_mgr_load_path_uris();

 PathIndex = g_relation_new(2);
 g_relation_index(PathIndex, 0, g_int_hash, g_int_equal);
 decend(LADSPA_BASE "Plugin", "LADSPA");
}

void decend(char *uri, char *base)
{
	lrdf_uris *uris;
	unsigned int i;
	char *newbase;
	char *label;

	uris = lrdf_get_instances(uri);

	if (uris != NULL) {
		for (i = 0; i < uris->count; i++) {
			guint *uid = safe_malloc( sizeof( guint ) );
			char *basedup = safe_string_dup( base );

			*uid = lrdf_get_uid( uris->items[i] );
			

			//printf("%s/[%d]\n", base, *uid );
			
			g_relation_insert( PathIndex, uid, basedup ); 
			//printf( "selct: %d\n", g_relation_count( PathIndex, uid, 0 ) );
		}
		lrdf_free_uris(uris);
	}

	uris = lrdf_get_subclasses(uri);

	if (uris != NULL) {
		for (i = 0; i < uris->count; i++) {
			label = lrdf_get_label(uris->items[i]);
			newbase = malloc(strlen(base) + strlen(label) + 2);
			sprintf(newbase, "%s/%s", base, label);
			//printf("%s\n", newbase);
			decend(uris->items[i], newbase);
			free(newbase);
		}
		lrdf_free_uris(uris);
	}
}
