Creating and managing visual documentation, such as diagrams and schematics, in the IT industry using DITA XML is essential for conveying complex technical concepts effectively. DITA provides structured methods to handle visual content within documentation.

Image Elements

DITA allows for the inclusion of images within documentation topics. These images can be referenced using the <image> element, which specifies the path to the image file and other attributes. Here’s an example:

<image href="diagram.png" placement="inline" scalefit="yes" />

This example demonstrates how images, like diagrams, can be embedded within the content, ensuring that visuals are an integral part of the documentation.

Alt Text for Accessibility

Accessibility is crucial in IT documentation. DITA supports the inclusion of alternative text for images to make content accessible to individuals with disabilities. Here’s how alt text can be added:

<image href="network_topology.png" placement="inline" scalefit="yes">
  <alt>Network Topology Diagram</alt>

By providing alt text, organizations ensure that all users, including those using assistive technologies, can understand the content.

Image Versioning

Just like textual content, visual documentation often requires version management. DITA allows for versioning of images by including version information within the topic structure. For instance:

<image href="architecture.png" placement="inline" scalefit="yes" version="1.2" />

By maintaining versions of visual assets, IT organizations can keep track of changes and ensure the accuracy of visual documentation.
