Category maxes out at 7 entries[edit]

I just created Category:Authors and writers external links templates and populated it. With for example {{Gutenberg author}}. However Gutenberg author and many others are not showing up, staying in the parent cat of Category:People and person external link templates. It seems to have maxed out at 7 entries. I notice the other sub-cat to Category:People and person external link templates, Category:Canada politics and government external link templates, is also maxed out at 7 entries (though maybe its natural number, just suspiciously the same). Is 7 a bug, or feature? -- GreenC 15:39, 7 October 2014 (UTC)

Template updates cause an low priority task to start that updates the category later. So it is not instant and in the past has taken weeks. Vegaswikian (talk) 16:55, 7 October 2014 (UTC)
You edited the template documentation subpages like in [1]. That is the correct action but it's affected by the delay described by Vegaswikian. If you null edit the actual template pages then the category should update right away, but there is no need to use null edits for a minor issue like this. Just wait for it to eventually happen automatically. I realize it seems odd that the category is sometimes displayed at the bottom of the pages, but the pages are not displayed in the categories. However, the page and the category can be updated at different times when the categorization is done via a transcluded page. PrimeHunter (talk) 17:03, 7 October 2014 (UTC)
Ok thanks for the explanation (and Vegaswikian). Regards. -- GreenC 18:47, 7 October 2014 (UTC)

Alphabetisation mystery[edit]

Look at Category:Health ministries. You'll find two groups of entries under the letter I - one in the usual place, and another one between D and E just containing Ireland. I've checked that both 'I's are in fact the same Unicode character, so what's happening? Colonies Chris (talk) 09:32, 1 November 2014 (UTC)

I don't know what was causing it, but I've fixed it (by temporarily changing the sort key to "ZIreland" and then changing it back to "Ireland"). DH85868993 (talk) 11:20, 1 November 2014 (UTC)

transcluding a category into an article[edit]

is it possible? here's an example: replacing the link to category with a category transclusion in Copernicus Publications#See also. Thanks. Fgnievinski (talk) 04:40, 6 November 2014 (UTC)

It's possible, but doing so will only show the contents of the category page, rather than the members of the category itself, which isn't usually what you want. Jackmcbarn (talk) 04:55, 6 November 2014 (UTC)

Why all these saint categories for one article?[edit]

I just saw someone changing a category from Medieval Scottish saints to Medieval Roman Catholic Scottish saints at Saint Ninian and noticed he is now in 7 'Saint' categories. Does this make sense? Thanks. Dougweller (talk) 09:09, 14 November 2014 (UTC)

According to Wikipedia:Categorization#Categorizing pages, "each categorized page should be placed in all of the most specific categories to which it logically belong", so that change is correct, given the current category structure. Whether we should have that many specific ("Medieval Roman Catholic Scottish ...") is a separate matter. WP:OVERCAT is the relevant guideline. Mitch Ames (talk) 12:20, 14 November 2014 (UTC)
Thanks. I'll ask there. Dougweller (talk) 14:40, 14 November 2014 (UTC)

Putting articles of eponymous categories in parent cat[edit]

Input from editors familiar with categorization is requested at Talk:Paddle steamer#Category:Ship types. Mitch Ames (talk) 05:32, 16 November 2014 (UTC)

Proposed clarification[edit]

The above-mentioned disagreement has been resolved, by reference to WP:EPONYMOUS. However it does highlight the fact that the WP:EPONYMOUS exception to the general rule of WP:SUBCAT is not mentioned in SUBCAT or the first paragraph of WP:CAT#Categorizing pages (as non-diffusing categories are). I suggest that it should be. Thus I propose the following changes to Wikipedia:Categorization:

Categorizing pages

... In addition, each categorized page should be placed in all of the most specific categories to which it logically belongs. This means that if a page belongs to a subcategory of C (or a subcategory of a subcategory of C, and so on) then it is not normally placed directly into C. For exceptions to this rule, see Eponymous categories and Non-diffusing subcategories below.




A page or category should rarely be placed in both a category and a subcategory or parent category (supercategory) of that category (unless the child category is non-diffusing – see below – or eponymous). ...

Support, comments or objections? Mitch Ames (talk) 12:09, 1 December 2014 (UTC)

I've made the change. Mitch Ames (talk) 12:24, 9 December 2014 (UTC)

Toponyms by language[edit]

I don't understand why categories like Category:Romanian toponyms are not allowed. Since Category:Slavic toponyms and Category:Latin place names, why it can't be another one for Romanian, another for German and so on?

Where can I gather together Romanian language toponyms like Păltiniș Păltinișu, Peșteana, Peştera (disambiguation) and other disambiguation pages like that? At least can I make a list with them?

I have read Wikipedia:Categories for discussion/Log/2012 November 26 and Wikipedia:Categories_for_discussion/Log/2012_November_13#Category:Norwegian_toponyms but I don't see any valid reason to remove such categories.

If a name like Banka is used in both Slovakia and India, it can be put in both Category:Slovak toponyms and Category:Hindi toponyms. If a name belongs to many languages (like Alba), then it can be added to categories in a invisible manner, so it won't bother the reader with too many categories. —  Ark25  (talk) 04:43, 8 December 2014 (UTC)

As far as your last point is concerned, categories are either hidden, or they are not. There is no facility for them to be hidden on some pages and visible on others. All the best: Rich Farmbrough17:43, 13 December 2014 (UTC).
