Accessibility in Orbis

Orbis Accessibility

Ex Libris development has focused on accessibility compliance for Orbis.

The tactics and techniques used for accessibility compliance in Orbis were derived from discussion documents and use of tools including the FAE (Functional Accessibility Evaluator) tool. The FAE tool analyzes web content based on the use of CITES/DRES Html Best Practices (see for web development.

For example, one of the practices used is to declare a headings level 2 tag, <h2>, within ordered, <ol>, and unordered, <ul>, lists. The <h2> tag describes a descriptive label for a collection of links.

Since JAWS (see allows users to navigate web content via headers, <h1> ... <h6>, this is a good way to break up the web interface into logical components.

Orbis implements the use of <h2> headings within lists purely for accessibility navigation. The header is positioned off-screen using css so that a non-screen-reading user does not see the header.

As you work with Orbis, you will observe other characteristics of accessibility compliance.
