Commons:Monuments database/Missing commonscat links
This page contains an overview of Missing commonscat links discovered in lists of monuments. These are categories on Wikimedia Commons (commonscats) that are specific to a given monument but where there is no information about this category in the lists on Wikipedia. To help you add these the 'missing commonscat links' pages have been developed. They list potential Commons category candidates that could be added to the lists based on the use of monument templates on Wikimedia Commons. All the pages and the statistics are updated on a regular basis by a bot.
How does it work?
Every night a ErfgoedBot updates the Monuments database with all the lists we have on Wikipedia. One of the values it identifies is if there is a known Commons category for a particular Monument. After it has looked at all of the lists it examines all of the use of monument template on Wikimedia Commons. If it comes across a monument template on a Category page, and that monument does not already have a category connected to it then it makes a note of this and reports it on the missing commonscat links page.
How can you help?
Go to the missing commonscat links page (linked below). Look at the suggested categories and if appropriate add them to the lists on Wikipedia. If they are completely inappropriate then remove the monument template from the category on Commons.
