Working with Categories¶

Creating a new Category¶

For creating a new category, create a new mediawiki page in the Category namespace and give the new category a distinct name

1	`Category:Employee --> creates a new page named 'Employee' in the 'Category' namespace`

Enter additional information about the category on its page

Adding wikipages to a category¶

To make a mediawiki page a member of a category, add a link to the category on the page

1	`[[Category:Employee]] --> Adds the current page to the category "Employee"`

Category Hierarchies¶

Mediawiki allows to build category hierarchies, i.e., it employs super- and sub-category concepts to resemble the ‘broader’ and ‘narrower’ relationships between categories known from taxonomical classification systems.

In order to make a category a sub-category of another category, add [[Category:{Super_category}]] to the sub-category page.

Example:

On the category page 'city':
============================

[[Category:Settlement]] --> makes 'Settlement' the super category of category 'city'

Note

Please note that category hierarchy can be any graph (multi-inheritance, cycles, etc.)

Linking to a Category¶

To create a link to a category, use a leading colon before the category name (without this colon, the current page would be added to the category):

1	`[[:Category:Help]] −−> Link displays as "Category:Help"`

To change the link text, write the text inside the link tag after a pipe:

1	`[[:Category:Help\|Help category]] −−> Link displays as "Help category"`

Category links can be placed at any location at a wiki page. However, due to maintenance and consistency reasons, it is good practice to define distinct locations in wiki pages for specifying category memberships. ↩
