Help:Classification in categories
Contents
Classification in general 
Classification in categories is essential to find quickly articles or media types or just for a classification. [[Category:Flora]] creates a category. But it has to be mentioned that it will not be found by a standard search, because this page isn't esteablished yet really. To do so you have to click the red link from the category's name and add a description or purpose of this particular category. An added colon, however, creates only a link to the category, e.g.: [[:Category:Flora]].
Sorting
In general each category or page is sorted by it's name, but it's also possible to alter this behaviour:
| Wiki-Page Abies alba … |
Now this category will be sorted differently as given and not like “Abies alba”. In a similar way you can alter the way of sorting of categorised words themselves:
- Example
- On a page named “Resource Subtype” you can sort it to “Subtype” (i.e. letter S) by adding the optional sorting word after the vertical bar “|”:
[[Category:Metadata | Subtype]].
Nesting
It's also possible to nest categories in the following way and create sub-categories:
| Page with [[Category:A sub-category]] |
Sub-category's page with [[Category:Super-category]] | ||
| follow link of category→ |

Classification using template “Metadata”
For media data a special template was developed that handles categorisation as well. Here is an example for a German description of a Heteropteran wing description:
{{Metadata
| Type=StillImage
| Title=Wanzenflügel mit Legende
| Caption = Ein Wanzenflügel für Erklärungen in Bestimmungsschlüsseln.
| Scientific Names = Heteroptera
{{en| inline=1 | Heteroptera }}, {{de| inline=1 | Wanzen}}, {{cz| inline=1 | Ploštice}}, {{fr| inline=1 | Heteropter}}, {{fi| inline=1 | Luteet}}
| Metadata Language=de
| Language = de
| Creator= [[User:GiselaWeber]]
| Subject Category = Insecta, Heteroptera
| General Keywords = Morphological details, Legends, Schematic drawings, Wings (Insecta)
}}
…which produces:
