Disputatio Vicipaediae:De categoriis

message: You have marked :Categoria:Auctores for deletion and I believe you have reasons why you think we should not use :Categoria:Auctores. In this case it is not obvious to me why it should not be used. Even if we had discussed the reasons anywhere, this would not keep people from creating it again. This is the reason why I am generally looking for other solutions than deleting something. It's a similar discussion as I had about  with Ioshus Rocchio. Alternatives which cross my mind, depending on the reasons:
* a REDIRECT to :Categoria:Auctores
* a template saying that this is an unwanted category and categorizing the category below :Categoria:Unwanted categories
* a REDIRECT to :Categoria:Scriptores and adding a remark there, saying that :Categoria:Scriptores is the preferred name for :Categoria:Auctores
* etc.
Maybe the categorization pages should keep some hints for categorizing, I mean: what should go into that category and what not.
What do you think?
BTW ... shouldn't we better discuss this on the talk page of :Vicipaedia:Categoria?

replies: text: Concerning the special aspects at hand: I could not identify any difference in meaning between :Categoria:Auctores and :Categoria:Scriptores. I thus believed that this is a case of unwanted duplication, where some articles end up in one category and others in another category, while in fact all those articles should go into one common category.

text: I do not prefer any one of the two category names over the other. The only reason why I chose to mark :Categoria:Auctores (and not :Categoria:Scriptores) for deletion is that the former had only one entry while the latter currently has 30 entries and six subcategories.

text: Alternative: If one understands auctor in a broader sense, one might argue that :Categoria:Auctores should be a supercategory for :Categoria:Scriptores, :Categoria:Pictores, :Categoria:Compositores and possibly also :Categoria:Artifices.

text: Concerning the general aspects at stake: I would prefer deletion of any “unwanted” category over any other solution for the very simple reason of red links versus blue links: If an article is added to a non-existing category, everyone gets a clear visual indication (a red category link) that something is wrong here. If, however, there is any content to a category page (a redirect [are redirects between categories technically possible at all?] or a template saying this is an unwanted category), category links will show up in blue and the article will definitely not show up in the desired category.

text: In my view, the more meaningful and the more systematic our hierarchy of categories (and its documentation on Vicipaedia:Categoria) is, the easier it will be to place articles in the correct categories.

text: How to “keep people from creating” unwanted articles/categories:

text: # put those on your watchlist (it is possible to watch non-existing pages) and you will see them when they are created

text: # create a page (a subpage of your user page or a page in the Vicipaedia namespace) with links to the unwanted pages and you will see when a red link turns blue.

replies: text: :Ok, it really seems to be better to delete unwanted categories.

text: :Concerning :Categoria:Auctores versus :Categoria:Scriptores: I am not sure. I'd follow the definition of Auctor in :de:Autor, so Scriptor might be a synonym of Auctor or part of it. Maybe it would help if we had an article Auctor or Scriptor where this question could be clarified. Alternatively we could put a remark on the category page. For me, Scriptor is easier to use. BTW, shouldn't :Categoria:Poetae be part of :Categoria:Scriptores? --Roland2 13:49, 25 Maii 2006 (UTC)

thread_title:  Category names (proposal) 

message: An article should not be categorized in Supercategories. "Germania" is a supercategory of "Urbes Germaniae" (Terra -> Europa -> Germania -> Urbes Germaniae). "Urbes Europaeae" is another supercategory of "Urbes Germaniae". The category (!) "Urbes Germaniae" should be categorized in "Urbes Europaeae", "Germania" etc. but not in "Europa" or "Urbes". "Caesar" should be categorized in "Imperatores Romani", "Viri militares", ... maybe "Calendar" etc. but not in "Homines".

Ok, these receipe will bring up the same result: How to categorize an article?
* Step 1: Be as specific as possible: :Categoria:Poetae is better than :Categoria:Homines, :Categoria:Vindobona is better than :Categoria:Austria, :Categoria:Urbes Germaniae is better than :Categoria:Urbes.
* Step 2: Choose a category for each aspect: Leonardus Vincius is in :Categoria:Italia | :Categoria:Artifices | :Categoria:Architecti | :Categoria:Mathematici | :Categoria:Inventores.
* Step 3: Then remove the "supercategories". A category is a supercategory if it is a parent or parent-of-parent or parent-of-parent-of-parent or ... category of a specific category. The article Alabama should be in :Categoria:Alabama but not in :Categoria:Civitates Americae Unitae because this is a supercategory of :Categoria:Alabama. This avoids redundancy.
The advantages:
* If we had 50 articles in :Categoria:Poetae we could move :Categoria:Poetae from "Homines" to "Artifices" without touching these 50 articles.
* If we had 50 articles in :Categoria:Urbes Germaniae and we put just :Categoria:Urbes Germaniae into "Germania" and "Urbes Europaeae" we had indirectly all of these 50 articles in both "Germania" and "Urbes Europaeae". There is no need to put the :Categoria:Germania into these 50 articles. — If you need a new category, just create it. ;-)
* In short: it is better maintainable.

thread_title: Supercategories (proposal)

message: In the last few days, people seem to have been unsure where to use :Categoria:Homines directly and where to use :Categoria:Biographia.
For the reasons which have already been discussed above, I would strongly advocate to add persons to specific categories only and not to any supercategory of the category/categories chosen. That is to say: Once one has chosen :Categoria:Scriptores Romani Antiqui, do not add your article to :Categoria:Scriptores nor to :Categoria:Homines. :Categoria:Homines should really be a "fallback" category only, in case one does not have any appropriate subcategory at hand.
Regarding :Categoria:Biographia as it seems to be used at present, this category seems quite redundant to me. If we added every article about a person to this category, then there would be no difference to :Categoria:Homines. In my view, we should use this category not for persons, but for books about the life of a person (see e. g. en:Category:Biography, en:Category:Biographies, de:Kategorie:Biografie, fr:Catégorie:Biographie).
Any views on this? --UV 21:31, 22 Octobris 2006 (UTC)
replies: text: I agree with you. We should put :Categoria:Biographia into :Categoria:Libri maybe and put some usage information on page :Categoria:Biographia. --Rolandus 12:56, 26 Novembris 2006 (UTC)
I agree for the category "homines" but not for Biography. If you are looking for a personage and you are not sure if he was a writer or a philosophe, it's important to have a supercategory where you can find all the persons --Massimo Macconi 16:43, 26 Novembris 2006 (UTC)

text: I am not sure whether I have expressed my opinion in clear terms above. I think that

text: * :Categoria:Biographia should not contain any article about a person. Instead, it should only contain articles about books about persons.

text: * persons should be added to one or more specific categories, but not to any supercategory thereof. If a person was a composer and a philosopher, the article should be added to both categories. If a person was a philosopher and a Roman philosopher, the article should be added to the latter category only (because "Roman philosopher" is a subcategory of "Philosopher"). A page should be added to a general category (like "Philosopher" or "Homines") only if there is/one does not know any appropriate subcategory (like "Roman philosopher").

thread_title:  About [[:Categoria:Homines]] and [[:Categoria:Biographia]] 

message: Dear UV, I see that on the it.wiki the category "Biografie" is a general category which is about the life of a lot of persons and not only about books. From my point of view I believe that we must keep in line with the other wikipedias--Massimo Macconi 11:23, 27 Novembris 2006 (UTC)
replies: text: Here the Italian wiki is rather lonesome ;-) :it:Categoria:Biografie has no interwiki links. :en:Category:Biographies has 6 interwiki links and there (as well as on de) it is said that the category is just for books. In theory, whenever a person is an artist or a writer, he/she should be in both categories. However, I know that in practice this is sometimes not true. But you could search in page Specialis:Allpages. I'd prefer UV's position, however, I personally could live with an exception if we really want this. In this case I would call this extra category "Omnes homines" maybe, not "Biographia". --Rolandus 00:02, 28 Novembris 2006 (UTC)
replies: text: :I like the idea that Biographia should be about biographies, not be biographies themselves. But then, like the lonely it page, it should be Biographiae.--Ioshus (disp) 01:33, 28 Novembris 2006 (UTC)

text: Without realising it, I have intruded into this discussion by creating :Categoria:Libri biographici. It seemed a good idea at the time, as a parallel to :Categoria:Libri historici etc. Andrew Dalby (disputatio) 18:18, 17 Decembris 2006 (UTC)
replies: text: : No problem! Should consensus evolve about the "homines" and "biographia" problems in the sense that I have suggested, then we should decide which one of the three titles (:Categoria:Biographiae or :Categoria:Vitae or :Categoria:Libri historici :Categoria:Libri biographici - emendavi, recte, ut spero:Iovis Fulmen 17:51, 30 Augusti 2008 (UTC)) is most appropriate for articles about books about persons. Then, we should merge any remaining categories. Greetings, --UV 22:15, 17 Decembris 2006 (UTC)
