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.html)
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. - Steve
