liblrdf is a lightweight RDF metadata handling library with extensions for
manipulating LADSPA Schema-specific data.
This version adds:
* MacOSX compatibility, courtesy of Taybin Rutkin
* A convienient method for reading control scale points
* A convienient method for writing preset information
An example showing how to use the two new methods can be found in
examples/scale_test.c and examples/setting_test.c
Scales are a way of mapping the semantics of port values to labels, eg.
that an oscilator wave control has known behaviours for 0, 1 and 2 mapping
to "sine", "square" and "saw".
An RDF scale description of his plugins is included with Tom's Audio
Plugins (http://www.hszk.bme.hu/~st444/tap/tap.html) and an RDF
description of the scales for mine is on the website
(http://plugin.org.uk/src/metadata/swh-scales.rdf, you can install it in
/usr/local/(share/)ladspa/rdf/) and will be included in the next release.
