::I've run [[:Category:Trams in Prague]] through [http://toolserver.org/~magnus/catscan_rewrite.php?language=commons&project=wikimedia&depth=3&ext_image_data=1 CatScan V2.0β] and it found 3184 objects (pages, categories and files) and searched 1133 categories, this means that there are 1133 categories within [[:Category:Trams in Prague]] to sort only 2051 pages and files, surely this can be consolidated down to about many fewer categories.

:::I've thought of a solution. We can convert all of the "Tram xxxx (Prague)" categories to hiddencats, so that one can still click a link and show all photos of an individual tram, and then ad the broader category ie [[:Category:Tatra T3 in Prague]], so images will also populate that category, and lower dramatically the amount of categories visibly nested in [[:Category:Trams in Prague]]. Ideas? [[User:Liamdavies|Liamdavies]] ([[User talk:Liamdavies|talk]]) 14:42, 18 March 2013 (UTC)

:I think, Commons should categorize on all relevant levels, not only on the higher ones. The adequate level depends (besides other) on amount of the uploaded photos (files) and subcategories. I thing, more than 2000 photos are enough to be categorized thoroughly. Categories should sort the content systematically, not group hundreds of photos to one big dump. Categorization system of wiki projects is primarily modular, not by tags or keywords. Even if some pieces have only one or two photos still, there is useful to enable to find them (and to group the two photos together) - and moreover, many pieces have more photos.

:I see no reason in converting these categories to hiddencats. They are standard item categories - just as categories of individual buildings, villages, people etc. They should be visible, properly categorized and not separated. "Hidden" mark would solve absolutely nothing. Category of an individual vehicle must be certainly visible and foundable in the category of the corresponding type, so the amout of subcategories would not drop by such action. If we want some "summary" view, we can wait for some tool to effective browsing of subcategories or create some paralel category branch (trams by view etc.) or overview galleries but we should not destroy or paralyse the current detailed categorization by number.

:You are right that pieces of the newest types (Škoda 14T, Škoda 15T) have very short specific history (and only several of them have or had a specific advertisement coat or some specific equipment like WiFi), but it would be not desirable to differ categorizing standards for every type of tram. Btw, the type name is not so good visible on the vehicles as the fleet number, thus the number is more practical for the basic level of categorization. The simple unified system is very friendly who is searching or uploading a photo of a real vehicle.

:[[:Category:Tram_6138_(Prague)]] is obviously not an useless category. It is not empty but it contain one subcategory, which means that we have no photo of this tram before the reconstruction and renumbering yet, but we have some its photos past the reconstruction. Do you cannot see the subcategory, or don't understand the effort to associate the older and the newer photos of identic piece? We would make great thanks to the creators of that precise categorization.

:The files [[:File:Pivni tramway.jpg]] & [[:File:Nádraží Hostivař, 6815+6909.jpg]] are categorized by the visible trams and the trams are categorized by type. It implies from the basic principle of categorization: „Generally files should only be in the most specific category that exists for certain topic.“ Similarly, if we have a specific category for some king or president, the photos from such category are not categorized directly into the parent categories like "Kings of..." or "Presidents of..." I agree that modular categorization can be uncomfortable for some kinds of usage but it was chosen as the basic principle and have also many big advantages. --[[User:ŠJů|ŠJů]] ([[User talk:ŠJů|talk]]) 17:16, 18 March 2013 (UTC)
