[Biopython-dev] Phylo: support for JSON trees

[Eric Talevich]

Hi Fabio,

This is an interesting idea. I'm concerned that there are many ways to
represent a tree as a JSON string, just as there are many ways to represent
it in XML. Do any of the tree-oriented web apps you know of (including
BioJS modules) accept JSON input in a specified way?

Cheers,
Eric
