This paper describes the implementation of the PDF Accessibility Validation Engine (PAVE). PAVE is a web based application for identifying and correcting accessibility issues in PDF documents. The accessibility analysis is based on the PDF/UA standard.

We previously introduced the idea of such a system in [1]. The entire application runs on a web server, allowing users to both analyze a PDF document in regard to accessibility issues and then to directly fix these issues within the browser, thus relieving them from installing software. A simple and intuitive user interface allows both experts as well as users with only little previous knowledge of PDF accessibility to work with PAVE.
