Introduction

Hierarchical category systems like Curlie traditionally have been called classification systems. Taxonomy and ontology are additional terms used to describe the work of organizing categories. The goal in developing a category structure is to create a system that allows people to easily find material.

Curlie follows a peer review process, so no individual editor owns his or her category. Even if you are the only editor listed in a category, there will be other editors who will be able to edit and add sites there. These editors include parent category editors, editalls, metas and admins.

Editors have learned from experience that communication (e.g., by e-mail or by posting proposed changes in the appropriate editor forum) is critical to a successful editing process. When you want to make changes such as creating subcategories, or moving sites between categories, you should communicate with other editors before going ahead. Even if you are the sole editor of a category, you should communicate changes to parent category editors.

Creating Subcategories

Generally, subcategories may be helpful when the number of links exceeds 20, but creating subcategories when there are fewer than 20 links generally will hinder users' ability to find the desired information. Once a category has 20 or more links, editors may see groups of links that can be easily organized by subtopic.

If you edit outside of the Regional branch, you should sub-categorize and organize sites by topic whenever possible. When you have exhausted all possible ways of organizing sites by topic, you may organize sites by geographic area or by an alphabet bar, whichever is appropriate. Generally, organizing sites into alphabet bars should be done as a last resort.

Alternatively, you may decide to keep all your sites in one category. For example, the category Business: Transportation and Logistics: Trucking: Truck Sales: Used: North America contains 50+ links to sites selling used trucks. It is difficult to break this category up into topical subdivisions based on the type of product, since all sites seem to offer the same or very similar products and services.

If you are listed as editor of a category, you can automatically also edit in any subcategories or sub-subcategories underneath it, as a "parent editor". You don't need to name yourself as editor of subcategories that you create, and it is recommended that you not do so, unless it is a "pet" category or special interest of yours, where you expect to lavish lots of time and attention on building it up, or if you are acting as part of a planned reorganization that will lead to the subcategory being moved elsewhere, and you wish to continue to maintain the category after it is moved. Leaving smaller categories without a listed editor serves to attract new editors to join Curlie, and current editors to branch out into new areas. In extreme cases editors may be asked to resign from over-extensive lists of categories that they have editing access to "from above."

Choosing Subcategory Names

Curlie currently does not use a prescribed thesaurus for assigning subcategory names, however it is suggested that you utilize the Preferred Terms list where possible. The following guidelines may be useful in assigning names that will ensure consistency across the directory and prevent duplication of categories.

Note: Regional editors have developed their own prescribed and recommended list of subject subcategories to be used under geographic locations in the Regional branch only. Please see the Regional Guidelines for more information.

Duplicate and Related Categories

An effective editor will search and/or browse through the directory in areas inside and outside his or her top level category to find areas of potential duplication. Questions editors have found useful to consider include the following: Is my subcategory cross-disciplinary, and if so, what other areas could resources in my subcategory be classified under? If there is a subcategory in another area of Curlie that is similar to my subcategory, should I create a Related Categories link? Should I create an @link? (See also @Links below)

Topical Subcategory Names vs. Form Subcategory Names

Where a category's resources are related to one another by their topic (e.g., Civil War sites, Venture Capital sites), a good subcategory name meets the following criteria:
1. The subject is expressed using an English language term, or English equivalent of a foreign language word, whenever possible and appropriate. For some categories, it is appropriate to use non-English language words, such as scientific sites where the subject may be most commonly identified by a Latin word.
2. Words to describe the topic appear in a subject-specific dictionary or widely used thesaurus or are typically used by the news and media covering the subject area. The name should use the word(s) by which the topic is most commonly known. (e.g., E-Commerce instead of Electronic Commerce).
Where a category’s resources are related to one another by their form (e.g., Chat Rooms and Message Boards, News sites, Directories), a good subcategory name usually uses the word that is used most frequently in other areas in pertinent top category.

Characteristics of Helpful Subcategory Names

Helpful subcategory names

Do not use acronyms or abbreviations unless they are commonly understood
Do not repeat the name of the parent category

Collection of business news sites under Business
Don't use: Business News
Use: News and Media

Collection of TV production company sites under Arts: Television
Don't use: Television Production Companies
Use: Production Companies
Are not called "General," "Miscellaneous," "Other Topics," or any other variation that implies a collection of general or unrelated links. Links in these general, or catch-all categories should be placed at the top of the most appropriate topical category or moved to an appropriate topical subcategory.
The sites in a category such as Recreation: Outdoors: Hiking: Backpacking: General_Sites should all be moved to Recreation: Outdoors: Hiking: Backpacking. All general backpacking sites should be listed in the upper most relevant category in a subject branch. If there was a site in General Sites that was a site for a backpack manufacturer, then it should be moved to the Backpacks subcategory (which is under Shopping) rather than the main Recreation: Outdoors: Hiking: Backpacking category.
Do not use abbreviations or symbols (such as &, +, `n, or etc.) to represent words.

Don't use: Periodicals, magazines, etc.
Use: Magazines

Don't use: Resources `n Directories
Use: Directories

Don't use: Arts_&_Crafts
Use: Arts_and_Crafts
Do not use terms for subcategory names that would incorrectly suggest a category contains links to illegal content (e.g., Warez or Bootlegs)

Directories and Resources

Several categories in the directory have been created in order to list sites that are web directories or contain resources covering a particular subject area. The terms resources and directories are at times used interchangeably; however, they should be used to classify two types of sites that are quite different. The following is how Curlie defines the scope of Directories and Resources categories.

Directories

Use to classify sites that contain alphabetical or classified lists of resources covering a particular subject area.

Resources

Use to classify sites whose purpose is to provide a comprehensive overview of a particular subject area. Resource sites typically include general information about a topic, and provide directories, FAQs, chats and forums, publications, etc. Most resource sites should be listed in the main topical category. If the main category gets too large, the sites may be placed in a subcategory called Resources.

Changing the Name and Location of a Subcategory

Only editors with catmv (category move) permissions can rename and move categories. Simple changes, such as typographical errors and those that bring category names in line with templates and category guidelines, can be requested by posting to the "Category Move/Rename/Delete Requests" thread in the appropriate forum.

Complex changes such as those affecting hierarchy and ontology should be discussed and agreed upon by the editing community. Follow these tips and advice when reorganizing category hierarchies: Reorganizing Categories.

Do not manually make category changes by creating a new category, moving sites from the old category to the new destination category, and then deleting the old category. Curlie loses valuable logs and category navigation integrity when this happens. A catmv by an editor with appropriate permissions is the most efficient way to move large numbers of links. Editors found making manual category moves (manual catmvs) may have their editing permissions revoked. For further information, see The Perils of the Manual Category Move (catmv).

Regional Subcategories

The Regional branch of the directory is the place to list sites focusing on a specific geographic region. In general, the subject branches of Curlie contain sites that do not have a particular geographic focus and/or the sites are of global interest. If you are interested in creating a directory for regional and local resources, then you should consider becoming an editor in the Regional branch. A local resource is one that covers a limited area, usually within a country's state, province, or other equivalent administrative area (e.g. locality, metro area, county, region). Editors may create regional subcategories when no other type of organization will work. Please read the FAQ - Creating and Maintaining Regional Subcategories Under Topical Categories for more detailed instructions.
