This question is a follow-up to Is [*-lang] an acceptable tag? And [factor] discussion , which points out that the factor tag is in practice much more used for the "factor" data type in R than for the Factor language. There isn't a whole lot of discussion there, but the consensus seems to be that factor-lang and r-factor would be reasonable tags for the language and the data type, respectively.
My question, based on being fairly SO-active but not very meta-active: what's the protocol for this kind of (possibly) hostile takeover/usurpation/repurposing of a tag? Does one just ask on Meta and take the consensus answer as being SO policy? Is there a mechanism for asking the original tag proposers/editors if one wants to do it politely? Is there a "bulk retag" option to change most of the factor tags to r-factor (and manually change a few to factor-lang for the language or factoring for the mathematical operation, removing tags from those that are in none of these three categories) or do the interested parties just have to roll up their sleeves and retag ~150 questions manually?
Of course, we could just retag most of the questions as r-factor and leave the factor tag alone, but a bulk-retag option would still be useful, and I'm still curious about the 'usurpation' issue as a general question about SO ethics.
I have looked for answers on meta , without success (maybe I'm using the wrong search terms) ...
