Accessibility Statement for Share-VDE

This is an accessibility statement from Casalini Libri SpA.

Measures to support accessibility

Casalini Libri SpA takes the following measures to ensure accessibility of Share-VDE:

  • Include accessibility throughout our internal policies.
  • Appoint an accessibility officer and/or ombudsperson.
  • Assign clear accessibility goals and responsibilities.
  • Employ formal accessibility quality assurance methods.
  • Testing with aXe

Conformance status

The Web Content Accessibility Guidelines (WCAG) defines requirements for designers and developers to improve accessibility for people with disabilities. It defines three levels of conformance: Level A, Level AA, and Level AAA. Share-VDE is partially conformant with WCAG 2.1 level AA. Partially conformant means that some parts of the content do not fully conform to the accessibility standard.

Additional accessibility considerations

We have implemented end user customization options for color themes and bolder fonts.

Limitations and alternatives

Despite our best efforts to ensure accessibility of Share-VDE, there may be some limitations. Below is a description of known limitations, and potential solutions. Please contact us if you observe an issue not listed below.

Known limitations for Share-VDE :

  1. We are aware of: Entity page images do not have text alternatives because Images are imported from external sites and do not currently have text alternatives, since they represent the same as the headlines on each entity page. We may add text alternatives, but are not currently sure if this would be helpful. Please use the forum on to report bugs if you encounter an issue or have advice for improving this.
  2. We are aware of: Further testing needs to be done with NVDA, JAWS, Dragon, and more technologies because We have used aXe, VoiceOver and strived to adhere to best practices for AA compliance, but we want to test more to make sure there are not any issues we are not aware of yet. We will be testing within the next month and applying any changes. Please report any bugs or advice in the forum on
  3. We are aware of: More mobile testing needed because We have built the site to work on mobile environments and tested continuously, but a more in-depth mobile testing process needs to be performed. We will be testing within the next month and applying any changes. Please report any bugs or advice in the forum on

Assessment approach

Casalini Libri SpA assessed the accessibility of Share-VDE by the following approaches:

  • Self-evaluation
  • continuous awareness and adjustment of design and frontend implementation to adhere with best practices for accessibility guidelines
  • testing with aXe and VoiceOver before version release
