Content reuse in DITA is a versatile practice that can be applied to various types of content components, not limited to specific topics or elements. It allows organizations to efficiently reuse and reference different kinds of content, such as text, images, tables, links, or any structured information within DITA documents, enhancing consistency and efficiency in technical communication.

Content reuse in DITA is not restricted to a single type of content. It can be applied to various elements and data within DITA documents, making it highly adaptable. Common types of content that can be effectively reused in DITA include text, images, tables, links, structured content, and variables.

Text:

Blocks of text, sentences, or paragraphs can be reused across documents. For example, common instructions, disclaimers, or product descriptions can be created once and referenced in multiple places.

Images:

Images and graphics are often reused for consistency. Logos, icons, diagrams, or product illustrations can be stored in a central location and referenced across documents.

Tables:

Tables, especially those with consistent data like technical specifications, can be created once and reused in various documents. This ensures data accuracy and consistency.

Links:

Hyperlinks and references to external resources, such as websites or documents, can be reused for easy maintenance and consistent linking.

Structured Content:

Elements like steps, substeps, warnings, notes, or lists can be reused to maintain a consistent structure and formatting in different documents.

Variables:

DITA provides a mechanism for defining variables. For example, a variable for a product name can be reused throughout documents, and when the product name changes, it can be updated in one place.

Example:

A product documentation set for a software application includes various content types:

Text: Common installation instructions, legal disclaimers, and company contact information are used across multiple documents. Any updates or changes can be made in a single location and are reflected throughout.

Images: The company logo appears at the beginning of each document. Instead of embedding the logo directly into each document, it is stored as a reusable image and referenced in each document.

Tables: A table displaying system requirements is the same for multiple software versions. This table is created once and referenced in various user guides to ensure accuracy and consistency.

Links: References to a glossary of terms or an online support portal are consistent across documents. These links are reused, simplifying maintenance and ensuring that users always access the correct resources.
