Hi,

Thanks for the initial summary Christophe and for comprehensive comments 
Carlos. Please find some more responses from me:

The first question is how are assignments assigned. For a previous Task 
Force (the "Evaluation Tools Task Force" [1]), we had a simple list [2]. 
TF participants volunteered to work on specific tools and their names 
were listed beside these tools. They were responsible to carry out some 
reviews of these tools and submit their feedback to the group. This 
worked pretty well and I think we should try this approach. Just a 
simple volunteering system where people keep themselves busy by signing 
up to do reviews.

The second questions is if the same TF participant should be doing the 
reviews of step 2 and step 3. The answer is ideally yes but it is not a 
must. For example, we may have a delay in reviewing the *content* of 
test samples and may therefore want to queue up test samples that are 
structurally ready. So structure review and content review should be 
considered as separate processes to make things simple for now.

OK, let's keep a separate list connecting test sample with TF 
participants who are responsible for reviewing them. I'll work on that 
list, probably an XML document in the shared CVS space so that we can 
all edit it.

Do we want to keep a history of the review comments? For example when a 
test sample is changed or otherwise resubmitted, it is re-reviewed. Do 
we modify the initial comment or create a new comment and keep the old 
one? What other requirements do we have for the tool(s) we will use?

Yes, this is a typo. Fixing...

I strongly agree with a timeout, and agree with keeping an eye on the 
"quorum". The number and the affiliation of the responders should be 
considered. I propose this be primarily the responsibility of our dear 
TF facilitators, but we all have the duty to help keep an eye too.

Accepting or rejecting a test sample shouldn't be the call of an 
individual, especially since we are aware that there is a subjective 
factor to the review (see the comment below). This is why this is only 
an output of step 5, after all the group has had the chance to review 
the test sample and to participate in the voting.

Step 3 is supposed to be a preparatory step to facilitate the review by 
the group. It is much easier to review a test sample in step 4 based on 
an initial review. The comments from step 3 can help point out specific 
things to look at for the convenience of the other TF participants. 
However, step 4 (an online strawpoll with a timeout) can only start 
after step 3 has been accomplished.

I hope this clarifies why these are separate steps, let me know if there 
needs to be further clarification.

Yes, we should get started and test the process. We already have three 
test samples uploaded by Vangelis and Daniela. We need three volunteers 
to do reviews...

Yes, the content review may have some subjective aspects, or at least 
criteria that are hard to define. This is why we have the collective 
review in step 4, and a collective decision in step 5. We should also 
continue working on refining the checklist as we go along and learn from 
our review activities.
