*Put the specialists category aside by grouping them in "item by xxx" categories.

*Put the specialists category aside by grouping them in "item by xxx" categories.

This is not perfect as you don't necessarily want on the top level technical details of components or interiors, but as stated, it is a compromise. In the past, we have already discussed ideas to be able to tag some images as most representative/best/postcard type/... and to allow category displays to filter on that, but software development on wikipedia seems to be halted since years, at least on Commons. Note that we have very often a similar problem to create long flat lists (people by name, ships/aircraft by registration number, ...), but this is easier to solve with "xxx by yyy" categories. Alternatively, one could think of a category called "trams running in Prague operated by xxx operator", as to avoid overcat fundamentalists. --[[User:Foroa|Foroa]] ([[User talk:Foroa|talk]]) 18:21, 22 March 2013 (UTC)

* Place each image into both '' in Prague'' and '' trams in Prague'', even though one is a subcat of the other. Ignore [[WP:OVERCAT]] where it is interpreted that no item should ever be included in a transitive supercategory. The reason is that each category here has a different [[:en:use case|use case]]: '''' is something like the tram model type, route or location (useful to many groups), whilst '''' is for tram-spotting individuals. Not my interest, not something I'd put interest into categorising (for mundane trams at least), but nor should I dismantle someone else's work in building such a category tree.

: As noted at the top, MW has many extensions such as DPL for making categories more powerful. However they won't be happening on WMF projects for good performance reasons. Sadly there's also a problem at WP especially, where categories are neither understood, nor used well. [[User:Andy Dingley|Andy Dingley]] ([[User talk:Andy Dingley|talk]]) 22:10, 22 March 2013 (UTC)
