Template:DEFAULTSORT
- Template:DEFAULTSORT – Controlling Article Categorization
Template:DEFAULTSORT is a crucial, yet often overlooked, feature within MediaWiki that significantly impacts how articles are organized and displayed in category listings. For beginner wiki editors, understanding and utilizing this template is essential for maintaining a clean, logical, and user-friendly wiki. This article will provide a comprehensive guide to DEFAULTSORT, covering its purpose, functionality, implementation, best practices, troubleshooting, and advanced considerations. We'll also connect its importance to broader wiki maintenance strategies.
What is DEFAULTSORT?
At its core, DEFAULTSORT dictates the *sort key* used when an article appears within a category. Without DEFAULTSORT, articles are categorized alphabetically based on their full page title. This can lead to a disorganized and confusing category listing, especially when dealing with articles that begin with articles like "The," "A," or "An," or with numerical prefixes.
Consider a category of articles about trading strategies. Without DEFAULTSORT, articles titled "A Beginner's Guide to Moving Averages," "The Power of Fibonacci Retracements," and "10 Tips for Day Trading" would appear at the top of the category, pushing more relevant entries further down. This is clearly undesirable.
DEFAULTSORT allows you to specify a different sorting key, effectively overriding the default alphabetical sorting based on the full title. In the examples above, you might use DEFAULTSORT keys like "Beginner's Guide to Moving Averages," "Power of Fibonacci Retracements," and "Tips for Day Trading," respectively, resulting in a much more logical and useful category arrangement.
Why is DEFAULTSORT Important?
- Improved Category Navigation: The primary benefit is a well-organized category structure, making it easier for users to find the information they need. Think of categories as the index of your wiki – a poorly organized index is useless.
- Enhanced User Experience: A logical category order boosts the overall user experience, encouraging exploration and knowledge acquisition. Users are more likely to find and utilize information when it’s easily accessible.
- Consistent Categorization: DEFAULTSORT promotes consistency across the wiki, ensuring that articles are categorized in a predictable and standardized manner.
- Reduced Maintenance: While it requires initial effort, implementing DEFAULTSORT correctly reduces the need for frequent category reorganization and cleanup. Proactive organization is always more efficient than reactive fixing.
- SEO Benefits (Indirectly): While not a direct SEO factor, a well-structured wiki with easily navigable categories can indirectly improve search engine rankings by increasing user engagement and time spent on site. This relates to overall wiki design principles.
How to Implement DEFAULTSORT
The implementation of DEFAULTSORT is remarkably simple. It involves adding the following code to the *bottom* of the page, typically within the category links section:
```wiki DEFAULTSORT:Your Sort Key ```
- Replace "Your Category Name" with the actual name of the category you're adding the page to.
- Replace "Your Sort Key" with the text you want the article to be sorted by within that category.
Example:
Let's say you're creating an article titled "The Impact of Volume Spread Analysis on Trading Decisions" and want to categorize it under "Trading Strategies." You would add the following to the bottom of the page:
```wiki DEFAULTSORT:Impact of Volume Spread Analysis ```
This will ensure that the article appears in the "Trading Strategies" category sorted alphabetically by "Impact of Volume Spread Analysis" rather than "The Impact..."
Best Practices for Choosing Sort Keys
Choosing the right sort key is critical. Here are some best practices:
- Remove Articles and Prepositions: Generally, remove leading articles ("The," "A," "An") and common prepositions ("of," "in," "on," "for," "to," "with") from the sort key. This ensures a more natural sorting order.
- Use Key Words: Focus on the most important keywords that describe the article's content.
- Maintain Consistency: Establish a consistent pattern for creating sort keys across the wiki. For example, if you always remove "The" from titles, do so consistently. Consistency is paramount in wiki standards.
- Consider Alternative Titles: If the article title is overly verbose, consider a shorter, more concise sort key that still accurately reflects the content.
- Handle Numbers Carefully: For articles with numbers in the title, decide whether to include the number in the sort key or spell it out. Consistency is key here. For example, "10 Tips for Day Trading" could be sorted as "10 Tips" or "Ten Tips."
- Use Lowercase: Sorting is generally case-insensitive, but using lowercase for sort keys can help avoid potential issues and maintain consistency.
- Avoid Special Characters: While MediaWiki generally handles special characters, it's best to avoid them in sort keys to prevent unexpected behavior.
Common Mistakes and Troubleshooting
- Placement: The DEFAULTSORT tag *must* be placed after the category tag. Placing it before will not work.
- Typos: Double-check for typos in both the category name and the sort key. Even a small error can prevent the article from being categorized correctly.
- Missing Tag: Ensure you haven't forgotten to add the DEFAULTSORT tag altogether.
- Conflicting Categories: If an article is assigned to multiple categories, each category should have its own DEFAULTSORT tag with a key appropriate for that category.
- Category View: Sometimes, changes to DEFAULTSORT may not be immediately visible in category listings. This is often due to caching. Try purging the page cache (see Help:Purge ) or waiting a few minutes for the cache to update.
- Hidden Categories: Ensure the category you are trying to sort into isn't a hidden category. Hidden categories, typically used for maintenance, won't display articles in the usual category view.
Advanced Considerations and Special Cases
- Multiple Categories: When an article belongs to multiple categories, you need a DEFAULTSORT tag for *each* category. The sort key should be tailored to the context of that specific category.
- Redirects: DEFAULTSORT applies to the target of a redirect, not the redirect page itself.
- Templates and Modules: If you're using templates or modules to generate category links, make sure the DEFAULTSORT tag is included within the template/module code. This is especially important for articles generated dynamically.
- Sorting by Date: For articles related to events or news, you might want to sort by date. Use a format like "YYYY-MM-DD" in the sort key to ensure correct chronological ordering.
- Sorting by Author: In some cases, you might want to sort by author. Use the author's last name as the sort key.
- Using Parameters in Templates: More complex scenarios may involve using parameters within templates to dynamically generate the sort key. This requires advanced knowledge of template programming.
DEFAULTSORT and Wiki Maintenance
Regularly reviewing and updating DEFAULTSORT tags is an important part of wiki maintenance. Pay attention to:
- New Articles: Always add a DEFAULTSORT tag when creating new articles.
- Category Reorganization: When you reorganize categories, review the DEFAULTSORT tags of the articles within those categories to ensure they are still appropriate.
- Article Title Changes: If you change an article's title, update the DEFAULTSORT tag accordingly.
- Broken Category Links: Check for broken category links and fix them. Broken links can disrupt the category structure.
- Category Size: Large categories can be difficult to navigate. Consider splitting them into smaller, more focused categories and updating the DEFAULTSORT tags accordingly. This relates to Information Architecture.
