Why is Category:Wikipedia Start-Class vital articles in People with 297 entries?

a red link although it has almost 300 articles in it? I'm not even clear who determines this. Wikipedia:Vital articles shows only 136 articles for people, reasonable as there are only 1000 covered. And yet another thing I've yet to learn, how in the world do I remove a category from a talk page?

Do you mean Category:Wikipedia Start-Class vital articles in People? If so, looking at the first in the cat, Talk:Abu Muslim Khorasani, it's in there because it has {{Vital article|level=4|topic=People|class=Start}} - of those three parameters, only |level=4 wasn't responsible for the cat. Most categories found on talk pages are there because of the banners and other boxes before the first section. Anyway, I've created it now, so that it won't show as a redlink. --Redrose64 (talk) 13:42, 25 April 2014 (UTC)

Thanks. I now understand and have found that there is an expanded vital articles page. Dougweller (talk) 15:49, 26 April 2014 (UTC)

Tagging a category for verifiability of members?

I was looking at Category:Neo-noir and while it's certainly better than some categories I've looked at with regard to the listed articles (hopefully) verifiably belonging to the category, it's not great either. If it was a bit worse I might consider taking it to CFD, but I'd rather see the underlying articles be improved, or less ideally, the category pruned to exclude the articles which don't verifiably belong.

Is there a template that can be applied to the category to call attention to it, so that invested parties have a chance to review and improve the underlying articles or remove them? If not, are there less extreme options available than either going to CFD or taking it upon myself to review all of the 354 category members? Thanks for your thoughts.

In my opinion, tagging the category will not produce results. This is an ongoing issue with categories that require maintenance. It is difficult to do. Yea, we can create the tag, but how do we determine if anyone is following up? So I guess I agree with your suggestion but how would we make it effective? Vegaswikian (talk) 18:36, 28 April 2014 (UTC)

Thanks for your input. I agree that tagging the category page itself could be ineffective, but at the same time it would at least be something. I do have a thought that perhaps the category tagging could propagate to all members of that category as a way of getting more attention ("The category X, which this article belongs to, has been tagged for verifiability concerns. Please review this article to ensure that it meets the criteria to be a member of that category, and so on and so forth..."), but I'm not at all sure that that would be a good or practicable idea. DonIago (talk) 18:52, 28 April 2014 (UTC)

I know there are occasions where I would like to tag a category in an article as citation needed or some such when it is not clear that the category should be used. But I'm not aware of any way to do something like that. Vegaswikian (talk) 19:21, 28 April 2014 (UTC)

There is Template:Category unsourced, but I'm not sure how many editors use that or are even aware it exists. I would tend to consider it more expeditious to just delete the category. That said, for a category with 300+ members manual tagging would be, to put it nicely, impractical. DonIago (talk) 19:33, 28 April 2014 (UTC)

Masada

I noticed this edit, removing all categorizes from an article into an eponymous category Category:Masada. I have the feeling this is not the way to categorize. On the other hand, I checked New York and saw that some, but not all, categories go through Category:New York. What do you say? Which categories should remain on the article page itself? Debresser (talk) 10:40, 11 May 2014 (UTC)

• Hi Debresser and thanks for your concern. Feel free to add whatever relevant categories to the main article page. There is no clear-cut pattern on WP for this. Sometime the main article and its category share the same category names at the bottom of their pages, and at other times it's only the main category that has the sub-categories at the bottom of the page. Either way both are legit. So feel free to also add back categories to the article page if you think that will help readers navigate to related topics more easily. All the best, IZAK (talk) 10:50, 11 May 2014 (UTC)

I was referring to WP:DUPCAT and WP:EPON. Debresser (talk) 11:32, 13 May 2014 (UTC)

Category:Wiki Loves Earth 2014 Nepal

I found Category:Wiki Loves Earth 2014 Nepal listed in Wikipedia:Database reports/Uncategorized categories, but can't figure out how to parent it. Any ideas?

It appears to consist of a series of pro-forma lists, which I presume some sort of project is working to complete. --BrownHairedGirl (talk) • (contribs) 20:01, 12 May 2014 (UTC)

Doubtless it has to do with the photo contest on Commons; the content will be lists of the natural-heritage sites that are eligible subjects. I guess it could go in Nepal geography-related lists. It should probably be named more generally, something like Natural monuments of Nepal, similarly to the lists of buildings &c. used by Wiki Loves Monuments.—Odysseus1479 01:43, 13 May 2014 (UTC)

All included?

Should articles on rivers, towns etc. be all included in their base category, such as Category:Rivers of Maine and Category:Rivers of Cumberland County, Maine or just Category:Rivers of Cumberland County, Maine? It doesn't make sense to me that we should sort these further and still include them in a base category. Thoughts?--TM 14:39, 15 May 2014 (UTC)

Generally once an article is included in a subcategory, that is sufficient. I guess rather then using both, the argument could be made that you don't need the subcategories. Vegaswikian (talk) 17:39, 15 May 2014 (UTC)

So it would be correct to include an article about a river in Cumberland County, Maine only in Category:Rivers in Cumberland County, Maine, not Category:Rivers in Maine and its county subcategory? User:Hmains created a category tree and has consistently fought my effort to simplify the categories and remove the state-level category when a county-level subcategory exists.--TM 11:51, 23 May 2014 (UTC)

For rivers, I would say that WP:DIFFUSE applies - if the river is categorised into Category:Rivers of Cumberland County, Maine, and that category is a member of Category:Rivers of Maine, the river shouldn't also be placed in Category:Rivers of Maine. If some of the counties in Maine don't have a "Rivers of xx County, Maine" category, the river can go directly into Category:Rivers of Maine until a subcat is created for the county.

However, similar matters have been brought up before, see this thread. --Redrose64 (talk) 12:22, 23 May 2014 (UTC)

It is highly unintuitive to only categorize rivers by county. Most readers would have no idea what counties a river passes through (and for most purposes, it is irrelevant. older ≠ wiser 13:40, 23 May 2014 (UTC)

• example a great example of "all included" is Category:Presidents of the United States - we want all presidents in there, even if some of them are in subcategories. "All included" is just another way of saying "All categories below should be treated as non-diffusing". There aren't any clear guidelines as to when this is or isn't a good idea. I think for rivers, it's probably fair to subdivide, unless the river crosses multiple counties - not clear on geography so not sure if that works or not.--Obi-Wan Kenobi (talk) 16:47, 23 May 2014 (UTC)

comment from categorizers on Category talk:Media manipulation

Hi folks -- We have a discussion a category talk page, and it would be helpful to have some other eyeballs / participants. Category talk:Media manipulation -- Thanks, Lquilter (talk) 23:13, 15 May 2014 (UTC)

Creating categories for one article

Is there any rule against creating categories that will have just one article? A user has recently started taking articles out of (for instance) Category:1963 elections in Europe and putting them in newly-created national subcategories (e.g. Category:1963 elections in Austria). The vast majority of these categories will only have one article, as no other elections took place in the country that year. Number 57 11:26, 17 May 2014 (UTC)

Austrian elections pre-1980 were sometimes in category 19xx elections in Austria (1949, 1953) & sometimes in category 19xx elections in Europe (eg 1956, 1959). Hugo999 (talk) 11:42, 17 May 2014 (UTC)

It's not good practice, see WP:OC#NARROW. --Redrose64 (talk) 11:44, 17 May 2014 (UTC)

"...unless such categories are part of a large overall accepted sub-categorization scheme..." per WP:OC#SMALL. Key words "overall" and "accepted". postdlf (talk) 17:06, 17 May 2014 (UTC)
