Category:Floor 500

All we know passes through Floor 500.

Floor 500 is the top-level category for the Tardis. Like its namesake from TV: The Long Game, our Floor 500 is a central hub for information. All pages are ultimately linked to this one. The category is divided into four major kinds of information: stuff within the fictional Doctor Who universe, fictional stuff that's not in the Doctor Who universe, behind-the-scenes production information, and stuff that helps the wiki itself run.

No individual article pages should be in here, or indeed any type of page except for the main page and four subcategories.

Four on the floor

Category:Time-Space Visualiser is by far the largest of the subcategories. It contains the vast majority of articles present on this wiki. All categories and pages within it contain information written from an in-universe perspective. That is, they are written on topics that have to do with the narrative "reality" of anything that this Wiki defines as being part of the Doctor Who multiverse, from the television series to Faction Paradox. Such articles are easy to spot, because they're written in the past tense and tend to treat their subjects as "real" things that once existed.

Still, there are some works of fiction that are not within our definition Doctor Who universe for one reason or another. Articles about such fiction can be found in Category:Non-DWU material. A word of caution: please make sure you read T:CAN and T:VS before adding any of these categories to articles. There are actually very few works of fiction which can be classed, according to our rules, as truly "non-DWU". However, this does not mean that those stories not intended by their authors to be set in the DWU, it is merely our way of working with a system to classify sources so that we can efficiently write high-quality articles.

N

Finally, there's Category:The Hub, which is an administrative category for things that help the wiki function. Most of the things that get put in this category do so automatically, because a little piece of code makes it happen. Unless you really start editing the structure of this wiki, though, chances are you'll never peek inside this folder.

Keep 'em separate

No article should be tagged as being in more than one of these four main categories. An article can — theoretically — belong to an unlimited number of subcategories, but all these subcategories must be a part of only one of the four main categories. For instance, an article cannot combine both valid and invalid sources in the main "body" of text. Nor can it be written from both the real world and in-universe perspectives.

Any invalid or real world information on valid pages must be placed in the "behind the scenes" section.

This last assertion may be harder to grasp. If you have a category like category:People from the real world — which tags real-life people like Charles Dickens who have appeared in Doctor Who — you may believe that such a category belongs both within Category:Real world and Category:Time-Space Visualiser. In fact, though, the article Charles Dickens is written from an in-universe perspective. That is, it's about Dickens' relevance to the history of that universe, not our own. Thus, the category only belongs in Category:Time-Space Visualiser. Such cases, though, are rare. Most of the time, it's perfectly obvious which main category should house an article.

Exceptions

Despite the general desire to keep things only in one of the four categories, there are a couple of very specific exceptions, both having to do with Category:Merchandise:

• It is possible for an article or category to be in both Category:Real world and Category:The Hub, because they're both real world categories. So far, the only category to cross over in this way is Category:Galleries, because galleries are created by a specific feature of wiki markup code, and because all the galleries in the category were displaying Doctor Who merchandise, organized under Category:Merchandise.
• Because of a specific enumeration of Tardis:valid sources, Category:Doctor Who role-playing games is both a part of Category:Merchandise and Category:Non-DWU material.

Nomenclature

As a general rule, we've tried to make the distinction between real world and in-universe categories easy. Take, for instance, broadcasters. There are broadcasters in the Whoniverse, like AMNN. And there are broadcasters in the real world, like BBC America. Clearly, they shouldn't be in the same category, but somehow the word "broadcaster" will probably appear in the two separate categories that these articles require. Generally, it works like this:

Unmodified nouns name subcategories within Category:Time-Space Visualiser, and if it's in Category:Real world, it's prefaced with the words "Real world". Thus Category:Broadcasters is about broadcasters within the Doctor Who universe, whereas Category:Real world broadcasters is for broadcasters that actual.
