Only really a toy, but:
Aparently, ages ago I made an online LADSPA 2 RDF metadata editor:
http://plugin.org.uk/md-creator/
(
http://www.music.columbia.edu/pipermail/linux-audio-dev/2004-October/010011…)
It's very similar to the stuff I knocked up last night, though its not
exactly the same (the namespace is different, and it uses ladspa: for
everything, not DC where it should). It generates and reads longhand-only
Turtle (AKA NTriples).
I might fix it up to match the current strawman at some point, but I dont
think it's important.
