Secretariat Updates

  • Status of normalization of GRIB2 template notes questions (GRIB 2 #118): will take some more time to finalize, each question will be posted as a separated issue.
  • Status of normalization of BUFR4/CCT notes (BUFR4 #74 and CCT #58): will take some more time to finalize, each question will be posted as a separated issue.
  • A new issue will be created to discuss if it is useful to indicate "deprecated" (or "discouraged" if more appropriate) in addition to "see Note X" in GRIB2 parameters that are "deprecated."

The list of issues proposed so far, divided into substantial ones and those with editorial nature.

Recommended practice of Github issue management

  • When a new proposal (issue) is created, the issue is generally assigned to the person who makes the proposal and put in "submitted" status.
  • Once the team agrees to the general approach and decides to go to validation status, chair moves the issue to "in validation" status and the Secretariat creates a branch. If further discussion is necessary, the issue is moved to "in discussion" status.
  • Once the team agrees to the final proposal, assignee consolidates the finalized the proposal in the original post, updates the branch, and post a comment saying "branch updated" with mention to Chair and the Secretariat. (Please do not change issue status.)
  • Chair confirms that the proposal is finalized and the associated branch is updated, and moved the issue to the "validated" status.
