[Tdwg-phylo] Publishing a trees in RDF

[Arlin Stoltzfus]

QED.  The technology is out there.  IMHO, the continual propagation of  
new tree-viewers by developers, and the sense of users that there is  
no tree viewer that satisfies their needs, is (in the medium-term and  
long-term) a cultural-organizational-educational problem and not at  
all a technical problem.

If this is true, then in order to solve the real problem, we need to  
think about  things like changes in funding structure, standards  
development, and modes of user engagement, not new graphics libraries  
that do just the right thing with only a few commands.
