Memory Alpha:Category tree
From Memory Alpha, the free Star Trek reference.
Please read through the policy below to familiarize yourself with our common practices and rules.
If you have any questions, suggestions, or complaints, please post them on the talk page.
With the implementation of MediaWiki 1.3, it became possible to sort articles into categories. In order to ensure that these categories will be useful to users of the wiki, it was decided that establishing a clear category tree prior to enabling the category system would avoid problems.
Because it is a labor-intensive process to remove or alter a category name once it exists (categories must be orphaned to be deleted, and they cannot be redirected), all categories must be approved by a user consensus, similar to the deletion consensus, except in this case the consensus must be reached before you create a category here on Memory Alpha. To suggest a new category, use the category suggestions page, is dedicated to consensuses on suggestions for a single category name. Before adding a new category suggestion to this page, you should browse our existing categories and the discussions related to them. Remember also that we want to categorize the article with the correct sort keys.

[edit] Provisional categories
As categories are approved, they will be listed in the next section of those two pages. Partially approved categories, marked with {{newcategory}}, are listed for discussion on separate sections of the above two pages; they can be browsed through Special:Whatlinkshere/Template:Newcategory, or Category:Memory Alpha provisional categories.
[edit] Existing categories
While an overall category structure is a work in progress, some categories have already been accepted by the community. Articles may be added to these categories:
- Category:Planets
- This is a list category (a category for instances of planets). This means that every planet may (and should) be included in this category. Don't include moons, planetoids, asteroids or other celestial bodies, colonies, cities, lists of planets or other articles related to planets. If the name of the planet contains a roman numeral, use a sort key in which this numeral is replaced by a double-digit (Example: [[Category:Planets|Rigel 07]] for Rigel VII).
- Category:Sectors
- This is another list category. Include all sectors, but nothing else - no quadrants, zones, areas, regions, systems, no lists of sectors or other articles related to sectors. If the sector is a numbered sector (for example, Sector 63), only use the number as the sort key (Example: [[Category:Sectors|63]])
- Category:Nebulae
- List category. Include all nebulae. No specific sort key.
- Category:Moons
- List category. Include all moons. No specific sort key.
- Category:Clusters
- List category. Include all clusters. No specific sort key.
- Category:Titles
- List category. Include all titles. No specific sort key.
- Category:Delphic Expanse
- This is a locational category. Anything (species, planets, terms) relating to the Delphic Expanse area should be listed here. While there is no specific sort key , general sorting rules apply (regarding ship prefix or last-name first for humans).
- Category:Mirror universe
- A category for anything relating to the Mirror universe. Only articles directly talking about "mirror universe items" should be listed here. General sorting rules apply.
- Category:Weapons
- A list category for all forms of weapons - except hand-held weapons, which belong in the subcategory Category:Hand-held weapons. General sorting rules.
- Category:Starships
- List category for individual starships. Subcategories for starships of major powers will be created, others should be added directly to this category. General sorting rules apply, for example ignoring prefixes.
- Category:Starship classes
- List category for all starship classes. General sorting rules.
- Episodes
- List categories for episodes of all series, and also movies. General sorting rules apply, regarding articles such as "The" or "A" (Example: [[Category:TOS episodes|Corbomite Maneuver, The]])
- Category:TOS episodes
- Category:TAS episodes
- Category:TNG episodes
- Category:DS9 episodes
- Category:VOY episodes
- Category:ENT episodes
- Category:Movies
Note that this is just a small sample of the categories that are currently in use. For a complete list, see the full category listing.
[edit] Maintenance categories
We also use categories to help with the regular maintenance task of listing specific articles somewhere ("attention needed", "featured article" etc.) by creating a category and adding it to the relevant template. The prefix "Memory Alpha" is used for all maintenance categories that are included via a template.
