Clave: CI  Ref: ICETC'17f Patricia Acosta-Vargas, Sergio Luján-Mora, Tania Acosta. Accessibility of Portable Document Format in Education Repositories. Proceedings of the 2017 9th International Conference on Education Technology and Computers (ICETC 2017), p. 239-242, Barcelona (Spain), December 20 - 22 2017. ISBN: 978-1-4503-5435-6. https://doi.org/10.1145/3175536.3175574 This article describes a study on accessibility in the Portable Document Format. This type of file is increasingly used on the Web. In order to make the format universally accessible, it is suggested to apply the standards defined by the World Wide Web Consortium in the Web Content Accessibility Guidelines 2.0. However, not all PDF documents are accessible. In this research, the accessibility of PDF files was evaluated when applying the PDF Techniques based on WCAG 2.0. As a case study, it was applied to the universities in Latin America with the highest academic prestige according to the classification of Webometrics. The evaluation of the documents found that, in general, universities have not been concerned with providing accessible documents. In this research, we study the problems encountered in documents and the solutions to generate more accessible and inclusive documents.
