Drupal Best Practices: Planning Information Architecture Carefully
When building a website, especially using a content management system (CMS) like Drupal, one of the most crucial steps is planning the information architecture (IA) carefully. A well-structured information architecture ensures that your site is not only intuitive for users but also scalable and easy to maintain over time. This is particularly important in Drupal, where the flexibility of the platform can sometimes lead to complexity if not approached thoughtfully.
In this post, we'll explore key best practices for planning your information architecture in Drupal, focusing on three primary areas:
- Content Types & Fields: Designing reusable content types and fields to avoid redundancy.
- Taxonomy: Using taxonomy for categorization and tagging to make content organization easy and efficient.
- Entity Reference: Leveraging entity references to create relationships between content types, fostering a dynamic, interconnected structure.
By the end of this article, you’ll have a clear understanding of how these practices contribute to creating a well-organized, scalable, and maintainable Drupal website.
Understanding Information Architecture in Drupal
Information architecture refers to the way information is structured and organized on your website. In Drupal, this includes how content is modeled, categorized, and connected. IA is important for several reasons:
- User Experience (UX): A well-planned IA ensures that users can find the information they need quickly and easily, improving the overall user experience.
- Scalability: As your site grows, a solid IA helps maintain order, preventing content duplication and ensuring that new content fits seamlessly within the existing structure.
- Maintainability: With a clear structure, it’s easier for developers and content editors to manage the site, making updates, enhancements, and content creation more efficient.
Let’s dive deeper into the three key components that contribute to a robust information architecture in Drupal.
Content Types & Fields: Designing Reusable Structures
What Are Content Types and Fields?
In Drupal, content types define the structure of different types of content on your site. For example, a “Blog Post” content type might have fields for the title, body text, author, and publication date, while a “Product” content type might have fields for the product name, description, price, and image.
Fields are the individual pieces of information within a content type. For instance, the “title” and “body” of a blog post are fields that hold specific types of data (text, images, numbers, etc.).
Best Practices for Designing Content Types and Fields
- Avoid Redundancy by Reusing Fields Across Content Types:
One of the most common mistakes in Drupal site building is creating redundant fields that perform the same function across multiple content types. For example, if you have a “Title” field in a blog post, news article, and product content type, it’s better to create a single, reusable “Title” field that can be used across all these content types. This approach saves time, reduces clutter in the administrative interface, and ensures consistency across the site. When planning your content types, think about what fields can be shared across different content types. Fields like “Author,” “Publication Date,” and “Tags” are common across many types of content, so creating them once and reusing them can simplify your site structure and make it easier to manage in the future. - Create Reusable Content Types for Similar Data:
If you find yourself creating multiple content types that share similar fields, it might make sense to consolidate them. For example, instead of having separate content types for "Case Study" and "Success Story," consider creating a single “Case Study” content type and using taxonomy or fields to differentiate between the two. By designing content types with reusability in mind, you can prevent data silos, ensure consistency across different sections of your site, and streamline content management processes. - Consider Future Growth:
When planning your content types, think beyond your immediate needs. Your site may start with just a few content types, but it could grow over time. Consider how new types of content might be introduced in the future and design your architecture to accommodate this growth. For instance, if you’re building an e-commerce site, you might start with basic content types like “Product” and “Category.” However, as your business grows, you might need to add more specific types like “Digital Product” or “Subscription Service.” By designing a flexible content structure from the beginning, you’ll be better prepared for future expansion.
Field Types: Choose the Right Type for the Right Job
Choosing the right field type is essential to building an efficient and user-friendly site. Here are some common field types and their ideal use cases:
- Text Field: Use for short text entries like titles or names.
- Text Area: Ideal for longer text, such as the body of an article.
- Image Field: Use for uploading images.
- Entity Reference: Useful for linking content together (more on this later).
- Boolean (Checkbox): Great for true/false or yes/no data.
By carefully selecting and reusing fields, you create a streamlined, maintainable content model that can grow alongside your website.
Taxonomy: Organize Content with Categorization and Tagging
What is Taxonomy in Drupal?
In Drupal, taxonomy refers to the system of organizing content into categories or tags. It allows you to create vocabularies (sets of terms) that can be used to classify content in meaningful ways. For example, if you run a news site, you might have vocabularies like “Topics,” “Regions,” or “Authors.”
Taxonomy helps both users and content editors find, filter, and manage content more effectively. It’s particularly useful for creating dynamic content displays, such as filtering blog posts by topic or organizing products by category.
Best Practices for Using Taxonomy
- Use Taxonomy for Categorization:
When planning your site’s information architecture, think carefully about how you want to categorize content. Taxonomy vocabularies are ideal for creating hierarchical categories, such as product categories, article topics, or blog tags. By organizing your content using taxonomy, you can easily create views and filters that allow users to explore content in a more structured way. - Limit the Number of Vocabularies:
While it can be tempting to create multiple vocabularies for every possible category, this can lead to confusion and overlap. Instead, aim to create a few well-defined vocabularies that cover the most important dimensions of your content. For example, a news site might have vocabularies for “Topics” (e.g., Politics, Business, Technology) and “Regions” (e.g., North America, Europe, Asia). When in doubt, start with fewer vocabularies and expand as necessary. Overcomplicating your taxonomy structure can lead to difficulty in managing and filtering content. - Use Tags for Non-Hierarchical Grouping:
In addition to hierarchical vocabularies (e.g., categories), Drupal’s taxonomy system allows for tags, which are non-hierarchical. Tags are a great way to group content in a more flexible way, enabling you to create relationships between content that don’t fit into a strict hierarchy. For example, on a blog, you might use tags to connect articles on similar themes. If a user clicks on a tag like “sustainability,” they’ll be able to see all articles that mention or relate to that topic. - Leverage Taxonomy for Views and Filters:
One of the powerful features of Drupal is its ability to use taxonomy to create custom views and filters. For instance, you can use taxonomy terms to create a page that displays all content related to a particular topic or to build a filterable search interface that lets users explore content by different criteria. By using taxonomy effectively, you can create a dynamic and interactive user experience that adapts to the needs and interests of your audience.
Entity Reference: Connecting Content Types
What is Entity Reference?
In Drupal, entity references are a type of field that allows you to create relationships between different content types. For example, if you have a “Product” content type and a “Review” content type, you can use an entity reference to link each review to the relevant product. This creates a more interconnected, dynamic site where content is related and easily accessible.
Entity references can also be used to link other types of entities, such as users, taxonomy terms, or files, creating rich relationships between different parts of your site.
Best Practices for Using Entity References
- Create Relationships Between Related Content:
One of the key benefits of entity references is the ability to create related content displays. For example, if you’re building a blog, you can use entity references to link related articles together. This not only improves the user experience by providing relevant content but also helps with SEO by creating internal links between pages. Another example is linking products and reviews. By using entity references, you can display reviews on the relevant product pages and vice versa, enhancing both content discoverability and user engagement. - Avoid Hardcoding Relationships:
Instead of manually linking content together in each post or page, use entity references to automate these relationships. For example, if you create a field that links blog posts to authors (who might be a separate content type), you only need to update the author’s information once, and it will be reflected across all their linked content. This approach reduces redundancy and ensures consistency, making it easier to maintain the site over time. - Leverage Entity Reference Fields in Views:
Just like taxonomy, entity references can be used in Views to create dynamic lists of related content. For example, you can create a view that shows all the products related to a specific category or all blog posts written
