There are other issues here as well. Technology advances rapidly, and
what once seemed a good choice may rapidly become dated. Without
wishing to start a flame war, I think Java applets are dead (sorry
Phylowidget), Flash is fading away (thank you Steve), and increasingly
we will see lightweight SVG and Canvas-based browsers, non-web based
browsers that exploit specific hardware (iPad anyone), and Google-
Earth based browsers.
I doubt one-size-fits all will work. Standards themselves won't
address this issue, and I personally doubt RDF is where we want to be
focussing efforts anyway. A decent JSON format for trees and
associated metadata would be much more palatable for developers. It's
worth remembering that the great success of Newick (and Nexus) was
largely due to the ease of parsing.
Regards
Rod
