How to contribute to the process of building and governing definitions?

* comment * column: post a comment to the current definition, tell us the motivation for a change (f.e. def-1: "Type" is too vague)

* corrections * column: corrections requested (f.e. def-1: use "climate models families") . If comments suggest a rejection decision (cf (3)DR bellow), this column can be left empty and one can fill directly the "new definition" column

* new definition * column: the replacing definition in case of rejection decision (cf (3)DR bellow) or corrections accepted (cf (5)CA bellow)

* status * column: is for governance decision about definition. Status can be one of the following:

  • (1) DS="definition submitted"; next step is (2), (3) or (4)
  • (2) DA="definition accepted"
  • (3) DR="definition rejected"; it is no worth to submit corrections, next step is (7)
  • (4) CS="correction submitted" (definition not accepted as it stands); next step is (5) or (6)
  • (5) CA= "correction accepted" next step is (7)
  • (6) CR="correction rejected"; next step is back to (4) or go directly to (7)
  • (7) NDS="new definition submitted"
  • (8) NDA="new definition accepted"
  • (9) NDR="new definition rejected"; next step is back to (7)

The roadmap for definition governance may apear somewhat "heavy", but the advantage of these multiple steps is that we do not expect the same person to fill-in all of the columns. One can only provide a comment on a submitted definition without changing its status (1); another person will submit a correction (4) and a third one (or the same one but in a second round) can propose a new definition (7) after having accepted (5) or rejected (6) the submitted correction.

Once harversted a set of accepted corrections (CA), a "new definion" is written and submitted (NDS).

The defintions are fixed when the status DA or NDA is reached.
