==Categories==

This page is a '''guide to categorizing opera-related articles'''. [[WP:CATEGORY|Categories]] are sometimes implemented on Wikipedia in an ''ad hoc'' fashion, henceand tend tocan be erratic, with new ones appearing all the time. HereThe are[[Portal:Opera/Categories|Opera category tree]] contains all the currently usedexisting categories forand operatheir sub-categories. (You can view the sub-categories by clicking on the '''[+]''' next to the category title.) topics:

===Operas===

===Operas===

===OtherBasic categories===

All opera title articles belong in:

*[[:Category:Operas]]. For further information see [[WP:DUPCAT|Non-diffusing subcategories]].

Operas are further categorized by language:

*[[:Category:Czech-language operas]] • [[:Category:Croatian-language operas]] • [[:Category:English-language operas]] • [[:Category:French-language operas]] • [[:Category:German-language operas]] • [[:Category:Hungarian-language operas]] • [[:Category:Italian-language operas]] • [[:Category:Russian-language operas]] • [[:Category:Spanish-language operas]]

by genre (which should be plural and in the original language to avoid confusion):

*[[:Category:Azioni teatrali]] • [[:Category:Ballad operas]] • [[:Category:Chamber operas]] • [[:Category:Children's operas]] • [[:Category:Comédies mêlées d'ariettes]] • [[:Category:Drammi giocosi]] • [[:Category:English comic operas]] • [[:Category:Farse]] • [[:Category:Grand operas]] • [[:Category:Intermezzi]] • [[:Category:Marionette operas]] • [[:Category:Minimalist operas]] • [[:Category:Multimedia operas]] • [[:Category:Music dramas]] • [[:Category:One-act operas]] • [[:Category:Opera buffa]] • [[:Category:Opera oratorios]] • [[:Category:Opera semiseria]] • [[:Category:Opera seria]] • [[:Category:Opéras-ballets]] • [[:Category:Opéras bouffes]] • [[:Category:Opéras comiques]] • [[:Category:Opéras féeries]] • [[:Category:Operettas]] • [[:Category:Pastoral operas]] • [[:Category:Rescue operas]] • [[:Category:Romantische Opern]] • [[:Category:Semi-operas]] • [[:Category:Singspiele]] • [[:Category:Tragédies en musique]] • [[:Category:Verismo operas]] • [[:Category:Zarzuelas]] • [[:Category:Zeitoper]]

and normally by composer, i.e.:

*[[:Category:Operas by Giacomo Puccini]]

(N.B. for the purposes of Wikipedia (and indeed other encyclopedias such as Grove), operettas are considered a subcategory of operas, so, for example, The Merry Widow is in Category:Operas as well as Category:Operettas.)

In practice a single opera title article will have many category tags at the foot of the page. The order in which these appear should start with the most specific and end with the most general. For example, Tosca belongs to the following categories:

<nowiki>

[[Category:Operas by Giacomo Puccini]]

[[Category:Verismo operas]]

[[Category:Italian-language operas]]

[[Category:Operas]]

</nowiki>

Please note that for typographical reasons '''stubs''' go two line spaces after category tags.

===Composers, critics, directors, librettists and managers===

All opera composers belong in [[:Category:Opera composers]]. (Separate categories for composers of different genres of opera are no longer used.)

[[:Category:Opera critics]]&nbsp;• [[:Category:Opera directors]]&nbsp;• [[:Category:Opera librettists]]&nbsp;• [[:Category:Opera managers]]

===Singers===

Singers are categorized by nationality, ie, [[:Category:French opera singers]] etc, and by voice:

[[:Category:Operatic sopranos]]&nbsp;• [[:Category:Operatic mezzo-sopranos]]&nbsp;• [[:Category:Operatic contraltos]]&nbsp;• [[:Category:Operatic countertenors]]&nbsp;• [[:Category:Operatic tenors]]&nbsp;• [[:Category:Operatic baritones]]&nbsp;• [[:Category:Operatic bass-baritones]]&nbsp;• [[:Category:Operatic basses]]

Operas are further categorized byminimally languageby:

===Other categories===

;Composer

There are three main categories for opera organizations: [[:Category:Opera houses]] (sub-categorised by country), [[:Category:Opera companies]] and [[:Category:Opera festivals]]. (Opera houses may also be found in other categories, such as city, e.g. [[:Category:Milan]], and buildings, e.g. [[:Category:Buildings and structures in Vienna]].) Associations etc. are under [[:Category:Opera organizations]].

;Genre

*[[:Category:Operas by genre]] (N.Bwhich should be plural and in the original language used in standard reference books to avoid confusion). forFor the purposes of Wikipedia (and indeed other encyclopedias such as [[Grove]]), operettas are considered a subcategory of operas, so, for example, ''[[The Merry Widow]]'' is in [[:Category:Operas]] as well as [[:Category:Operettas]].)

;Language:

*[[:Category:Operas by Giacomo Puccinilanguage]]

;Year of premiere

*[[:Category:Operas by year]]

===Further categories===

Opera terms are categorized under: [[:Category:Opera terminology]]. Audio and video recordings of opera on 78, LP, CD, DVD etc. are categorized under: [[:Category:Opera recordings]]. Publishers are under [[:Category:Opera publishers]], and publications under [[:Category:Opera publications]]. Topics which don't fall under any of the above can always be included (temporarily) in [[:Category:Opera]]. Lists of opera-related items are categorised in [[:Category:Opera-related lists]].

Other categories include [[:Category:Operas by setting|Operas by setting]]; [[:Category:Operas by world premiere ___location|Operas by world premiere ___location]]; [[:Category:One-act operas|One-act operas]]; [[:Category:Unfinished operas|Unfinished operas ]]; [[:Category:Lost operas|Lost operas]]; [[:Category:Operas by source|Operas by source]] (for operas whose libretti are based on plays, novels, films, etc.)

===Category sortingorder===

In practice a single opera title article will have many category tags at the foot of the page. The order in which these appear shouldgenerally startstarts with the most specific and endends with the most general. For example, ''[[Tosca]]'' belongs to the following categories:

[[:Category:Operas by Giacomo Puccini]]|[[:Category:Verismo operas]]|[[:Category:Italian-language operas]]|[[:Category:1900 operas]]|[[:Category:Operas]]

There is also a partially-implemented family of categories taking the form <nowiki>[[Category:YYYY operas]]; these form sub-categories of [[Category:NNth century operas]]</nowiki>. These are usually years of first performances.

Please note that forFor typographical reasons '''stubs'''[[WP:Stub|stub]] tags go two line spaces after category tags.

(Forms of Chinese opera are listed under [[:Category:Performing arts]] not opera.)

==Opera singers==

In addition to [[:Category:People|general biographical categories]], opera singers are categorized by:

==Other opera-related topics==

'''Alphabetical order in the listing of operas/people'''

Articles which don't fall under any of the below topics can always be included (temporarily) in [[:Category:Opera]]. For further possible categories, see [[Portal:Opera/Categories|the full category tree]] for all opera-related articles.

'''Organizations and venues''' (When adding these, please check each category for the appropriate sub-category, if any)

The titles of articles are sorted omitting the definite or indefinite article such as "A", "The", "Le", "La", "Les", "Der", "Die", "Das", etc. This is done using a "Default sort" tag, which is placed before the categories. For example [[La naissance d'Osiris]] requires <nowiki>{{DEFAULTSORT:Naissance d'Osiris}}</nowiki>. That means that the opera will file under N and not under L, although the actual article title ("La naissance d'Osiris") will appear in the Category listing under N.

*[[:Category:VerismoOpera operashouses]]

*[[:Category:Opera companies]]

*[[:Category:Opera festivals]].

*[[:Category:Opera organizations]] for associations such as [[Opera Europa]].

;Opera terms

*[[:Category:Opera terminology]] (Formsnote that forms of [[Chinese opera]] are listed under [[:Category:Performing arts]] not opera.)

'''Audio and video recordings''' (on 78, LP, CD, DVD etc.)

Two other points here: first, the default sort title should always start with a capital letter, as lower-case initial letters are filed after upper-case Z; second, if there's a special character or accent early in the title, the default sort title should not contain the special character/accent, for a similar reason. So, in the same category, if "Zéphire" isn't changed to "Zefire", it would file after "Zwerg".

;Publishers

;Lists

==Category sorting==

People have to be sorted in the same way, e.g. <nowiki>{{DEFAULTSORT:Verdi, Giuseppe}}</nowiki>, otherwise Verdi will appear under 'G' rather than 'V'.

To ensure that articles are listed in the correct order on their category pages, the {{tl|DEFAULTSORT}} tag needs to added at the beginning of the article's list of categories.

*The titles of articles are sorted omitting the definite or indefinite article such as "A", "The", "Le", "La", "Les", "Der", "Die", "Das", etc. This is done using a "Default sort" tag, which is placed before the categories.
