[MOBY-dev] BioMOBY Asynchronous Service Call Proposal v2.2

[Pieter Neerincx]

Hi Johan et al.,

Thank you very much for the updated proposal! It took me a few days  
to read the proposal and all the referenced standards, so I can  
imagine it took you quite some time to put this together. I think the  
big picture looks good, but I do have a few small comments /  
questions. I'll send them one comment / e-mail in order prevent mixed  
up discussions and lengthy e-mails...

Thanks,

Pi
