Invitation to a Meeting to discuss Ontologies for Phenotypes

Hi all,

Sorry for the short delay.  I was just getting ready to head off to 
the South Pacific with my class when this came.  But we are settled 
in now, in our tropical paradise, and I'm trying to catch up.

It was great that Pankaj came to our meeting in August; he did a fine 
job and the Deep Gene group got very interested in the potential 
overlaps between your efforts and ours.  I hope we could get together 
a joint workshop soon, and the idea of having it at the next PAG is a 
good one.  I'll be there myself, and we are having a Deep Gene 
sponsored symposium and workshop on "geneomics of plant reproduction" 
so there will be a good pool of people there with broad interests.

Would anybody like to be the organizer of a session on gene/phenotype 
ontologies in relation to phlogenetics?

Cheers,

Brent
