Forum:CT Archive/Canon/Legends image categorization

It seems, per the question raised at Forum:SH:Legends images, that some easy form of distinguishing between Canon and Legends images is needed to help reduce the number of images in the wrong continuity article. I threw together a simple system tonight, but after resistance at the aforementioned SH thread, I gave in and hereby propose a formal CT.

My system can be seen at Template:Information. It consists of one new parameter to the template, which is set to a value indicating its canonicity. This in turn adds a category (or two) to the file, which enables category intersections of subject categories and canonicity categories, enabling easier sorting through large subject categories. Links to CategoryIntersection are already present on every category page containing anything other than subcategories, and additional links can be easily added to enable one-click intersections with the canonicity categories.

Resistance in the SH has come in two forms. One says that we don't need any such system because people ought to check the source first. While true, a categorization system makes this step easier, plus this system eliminates the need to check dozens of images in a giant category before you find one that happens to be Canon (or Legends, as the case may be). The second proposes splitting the subject categories instead, meaning Category:Canon images of X and Category:Legends images of X. This seems to me to be too much extra work for not enough extra benefit; more manual work and/or more complicated bot work will be needed, and it simply produces the same results that are (or will be) only one additional click away on mine.

Adopt the proposed system

If people object to the fact that Special:CategoryIntersection returns text links instead of a gallery, I believe that can be solved with a little work, some JavaScript magic, and creative use of Special:Blankpage. &mdash;MJ&mdash; Comlink 03:55, December 24, 2014 (UTC)
