You can organize sites under each geographic category by topic according to the following guidelines and template for creating subcategories. Please note that subject subcategories may not be further built out by geographic area.

Topical Areas Under Each Regional Heading

Standard Subcategories

The following are the only topical subcategories that you may create directly under a geographic category or subcategory. You will not need to use all of these.


The Regional branch contains links to English language Web sites, and its users are assumed to have knowledge of the English language. Similar to other languages, there are regional differences on the use of English language vocabulary to express concepts and category names. In order for the Regional taxonomy to be as consistent, standard, and stable as possible, terms used for category names should generally be the same across the directory. The only place where English usage may differ in the Regional branch is in countries where British English is used in the print and online media, and spoken by its citizens. For countries where English is an official language, and British English is spoken by its citizens, editors may use British English for category names when different from US English. All other areas of DMOZ should use US English for category names.

Subcategorization of Topics

Creating Subject Categories

Before you begin creating subcategories, ask yourself the question:

Does the topical breakdown of the category duplicate the Regional taxonomy of a category in the main subject branches of DMOZ?

If yes, do not create subject subcategories, and create an @link to the category in the main subject branch. See related DMOZ Guidelines.

Let's say you want to create the following category:
Regional: Europe: United_Kingdom: Arts_and_Entertainment: Literature

This duplicates the existing category:
Arts: Literature: World_Literature: British_Literature

Do not create the category in Regional. Create Literature@ under the Regional: Europe: United_Kingdom: Arts_and_Entertainment category, pointing to Arts: Literature: World_Literature: British_Literature

Let's say you want to create a category for local Bicycling clubs in Maine:
Regional: North America: United States: Maine: Recreation and Sports: Bicycling

However, per the DMOZ Guidelines, there exists the following category:
Sports: Bicycling: Regional: United States: Maine

Do not create the category in Regional. Create an @link to the Sports category in the Regional: North America: United States: Maine: Recreation and Sports category.

If no, then you may create subject subcategories according to the template and guidelines given below.

When creating a topical subcategory in Regional, you should make sure that an @link is placed in the appropriate category in the main subject branch of the directory. The best way to do this is to post the following type of message in the Rename/Delete/Move/Sort Requests thread in the topical branch forum - I created the following category: <insert category string> Please create the appropriate @links in the <subject name> branch.

I created the following category:
Regional: North America: Canada: News and Media: Television
Please create the appropriate @link in the Arts: Television: Regional category.

Also make sure to place a related category link back to the topical area in the category being created. In the above example, the link should point to the Arts: Television category, not to the Arts: Television: Regional one.

Subject Categories Sample Template

There is some flexibility when building out topical subcategories. Use the sample template to help guide you when building out the taxonomy and adding sites. When using the sample template, please keep these points in mind:
