Hello,

Thanks a lot for your useful comments!
So here we are:

1. CHARCOAL SPECS

http://bionecho.org/terrapreta/charcoalspec.txt
I have updated it, taking into account Ron's comments. I also started to add
the unities of measurement, but for some parameters I'm not sure which is
the best one:
- heating rate
- charcoal yield
- thinning
- calorific value
- for the compositions in general, C, H content...
- same question for H2O, O2 sorption...
- same question for the remaining parameters in A.Biochar properties ->
Physical properties -> Charcoal physical properties! Btw, are there here
superfluous parameters?
- a measurement reference is also sometimes missing I guess, as soon as a
mass is provided (e.g. "initial charcoal dry mass (mg)"...relative to what?)

- should we express the productivity / economical value in general? How ?
- Ron what do you mean by "spreading width"? Is it different from the size
of the field where the experiment takes place?

2. REVIEWING PROCESS

I like the idea of a 2-steps reviewing. My proposition for the process:

0. Online form completion. The submission has the status "UNCHECKED".
1. Initial automatic syntax parsing (check if all mandatory fields have been
completed, if the values are in the permitted ranges...). If it's ok,
submission receives the status "WELLFORMED".
2. Submission sent to XV members of the group "VERIFIERS".
3. As soon as YV verifiers give their approval, the submission status
becomes "ACCEPTABLE". It is then sent to XR members of the group
"REVIEWERS".
4. As soon as YR reviewers give their approval, the submission status
becomes "ACCEPTED".

Following questions have now to be answered:

1. Who are the VERIFIERS ?
2. Who are the REVIEWERS ?
3. Values of XV, YV, XR, YR ?
4. How are the XR members selected ? (random?)
5. At which stage should the submission appear in the DB ? (i.e. with which
status?) The current status should then clearly appear online.
6. Which restrictions for the automatic parsing ? So what is required for
UNCHECKED->WELLFORMED ?

Sincerely yours,
Christelle
