Accessibility

This page details specific steps taken to make the Omni CMS environment more likely to generate accessible content, as well as steps you, the content creator/editor can take to ensure your content is accessible. While some of the information provided may be of use to the general web development community at SDSU, the intended audience is the group of users maintaining and creating content for SDSU in Omni CMS.

Please visit the Accessibility site for information intended for a broader audience.

Editing/Creating Content

Visit Creating a Page / Metadata or use the In This Section navigation to find more information about ensuring the accessibility of content.

Images

All images must have an alternative description which serves the equivalent purpose of the image. The description should omit words like "image" or "photo". Images should not contain text. Images provides a more detailed description of the related accessibility requirements.

Captions (synchronized to the media) must be provided. [WCAG 2.0 SC 1.2.2 Captions (Prerecorded) - Level A]

Video with Audio or Other Synchronized Media (Prerecorded)

How Omni CMS Can Improve Accessibility

Components

Components don't give the user the full WYSIWYG experience, but they do allow users to add complicated content to the page without requiring an understanding of the underlying markup. By presenting a form to the user, the content can be limited to very specific requirements and even validated before being placed on the page.

Toolbars

Toolbars are assigned to users based on their user level/access requirements. These toolbars determine which options are available to them within a WYSIWYG content region. The toolbars page goes into more detail about the differences between the provided toolbars as well as the reasons certain options were removed from the toolbars.

Templates

In some cases, the templates can catch inaccessible content which was entered into the editor (sometimes inadvertently and/or through the use of copy & paste from other sources) and modify, remove, or replace the content with a more accessible alternative. Defining these rules in the templates can be difficult and there may be multiple methods of inserting inaccessible content which have to be dealt with in different ways.

At some point we may include a list of these changes/replacements, but we don't have a definitive list of the desired modifications at this time.
