You've read the Statement of Work for your next client project: A full content audit of their website to prepare for the client's first migration to Drupal. This client has 50k+ PDFs on their website, and few (if any) are 508-compliant. Your job is to audit all PDFs for 508 compliance to support a new, accessible Drupal website. Scared? I was when it happened to me. This session shares tips I learned to audit PDFs for 508 compliance at scale and make new content that everyone can access in Drupal. We'll cover: - Key differences to audit accessibility for PDFs vs. HTML - Tools to audit for 508 compliance at scale - When to use web scraping vs. web crawling - A roadmap to prepare non-compliant PDFs for migration to Drupal - Concrete steps to make PDFs accessible from the start. - What participatory design is, and how you can co-design Drupal sites alongside users with accessibility needs.
