There used to be an established set of procedures for aging stale ITP and ITA wnpp entries, and setting them back to O.
As I recall, it was something like: If the ITA or ITP is more than a month old, then: QA/WNPP sends email asking if they still intend to package or need help, If no response that in a few weeks, the package is set back to O, RFP, or RFA, as appropriate. This used to be documented somewhere on qa.debian.org, IIRC, but I can't find it anymore. Particularly nice would be tables showing the status; something like http://qa.debian.org/orphaned.html. Also, a separate question: packages which transitioned from O to ITA are still officially orphaned, but we don't track them at http://qa.debian.org/orphaned.html, right? Finally, there seems to be a bug in the WNPP labels, because an ITA package could be either orphaned (and about to be adopted), or maintained with an RFA (and about to be adopted). Those are very different states from a QA standpoint; if it is RFA->ITA then the old and new maintainers have collective responsibility; but if it is O->ITA, then QA has the responsibility. Thomas
