[BiO BB] Graph Formats

[erick antezana]

Hello,
   does anyone know or use some XML-based exchange graph format for 
representing pathways/regulatory networks/etc ?

GraphML (http://graphml.graphdrawing.org/index.html) seems to be a nice 
format as well as GINML 
(http://www.esil.univ-mrs.fr/~chaouiya/Recherche/GINML/index.html)... 
could someone advice me which one to use? Pros ans Cons?

thanks in advance,
erick
