As tags are ordered by usage count, replacing
[maven] will encourage every asker to use
maven even if they use specifically maven-1 or maven-3.
So as @Pascal Thivent said, "don't retag
The best solution (IMO) is either to "blacklist"
[maven] to only have specific versions, or have
[maven] as a synonym to
I prefer the second solution :
- The synonym can be changed later (when
[maven-3] will be more common)
- If the tag is incorrect (the question wasn't really about maven-2 but about maven-1) it can be changed manually.
- I looked for the
[java-se] tag (which is a synonym to
[java]), and there is still today 12 questions tagged with
[java-se], so I suppose that when a tag become a synonym it doesn't change everything automatically. Even if
[maven] would be a synonym to
[maven-2], questions previously tagged with
[maven] would keep their tag until they're manually retagged to
[maven-1]. (But this point would have to be checked first)
This way :
[maven-3] represent maven in a specific version
[maven] is a simple synonym to the current most used maven version. Plus, as a synonym the
[maven] tag would have to be manually entered (with no completion), this way, less people would use directly this tag.
I thought there were an easy way to remove a synonym but apparently it will need moderator privileges (at least).
How and when decide that maven-3 is more used/common than maven-2 ?
I would say when there will be more questions with
[maven-3] than questions on
[maven-2], (yes it's totally subjective, but I think with some common sense everybody can agree on a point where maven3 is more popular than maven2).
[maven] for general questions is also a very good solution (see @dalle answer), the downside is the fact that
[maven] isn't really popular (compared to other maven tags) and will be even less if maven-1 question are correctly retagged, so people will mostly specify the version of maven when they'll tag their question and the
[maven] won't be as relevant as it should.
In the given example (windows, windows-xp, windows-vista, windows-7) the
[windows] tag is far more popular than others, that's why it works well. (and this was a weak argument)
