Hi Christophe,

This is great, thanks! It seems that we have several pieces in place. We 
should however reverse the order and start with the user requirements 
first. It seems that we would have two types of users:
  - Task Force participants
  - Public visitors

The Task Force participants probably need to:
  - see the full status list
  - sort/filter the status list
   + according to the assigned reviewer
   + according to the review status
   + ...
  - see the HTML view of the metadata
  - see the reviews for test samples
  - edit the reviews for test samples
  - edit the status of the test samples

The public visitors probably need to:
  - see a list of the ready test samples
  - sort/filter this list
   + according to Success Criteria
   + according to Technology
   + ...
  - see the HTML view of the metadata
  - download the test sample (or batches?)


I think that if we start at this user end as well as on the other end of 
seeing what we already have (as you have done below), then we could meet 
in the middle with a fairly good idea of what needs to be done.

Regards,
   Shadi
