Re: [Audacity-devel] LV2/LADSPA library summary

[George F. <faz...@gm...>]

Hello Lars,

I wouldn't like to influence your decision too much (mainly since my  
understanding
of the internals and dependencies of these libraries is still  
limited), but I have a small note.

If the semantic-web world really takes off there might be interest to  
use these libs for other purposes too.
As an example I already compiled them with audacity to extended the  
metadata editor and they might become
part of the Vamp plugin support as well.
I think it would be best to have the most general solution possible  
since Redland, Rasqual and Raptor
support quite different though sometimes overlapping functionality.
My main (less related) question really is whether static linking is  
there to stay in the long term?
(I used them installed as system libraries on os/x which worked just  
fine.)
