PDF accessibility — discovery and triage.
PDFs are usually the largest accessibility liability on a public-sector site. Parity gives them the same continuous attention as HTML pages: every PDF discovered during a crawl is queued for structural-heuristic analysis and tracked across scans.
What Parity checks
- Tagged-PDF (pdf-missing-structure) — checks the `/MarkInfo` `/Marked true` indicator. Untagged PDFs are functionally inaccessible to most assistive tech.
- Document language (pdf-document-lang-missing) — scans for `/Lang` in the catalog. Missing language hurts screen-reader pronunciation and language switching.
- Image alt indicators (pdf-image-alt-text) — detects image-subtype presence; flags candidates needing alt review.
- Parse error (pdf-parse-error) — pdfjs failure surfaces the PDF as needing attention.
How teams use it
Government sites typically host hundreds to thousands of PDFs in CMS asset libraries. Parity gives content managers a worklist that prioritizes by severity and recency, with copy-URL affordances for pasting back into the CMS asset search. Pairs naturally with a manual PDF/UA validator pass for the highest-stakes documents.
