Digital Accessibility in Archives
How can historically grown documents from archives be converted into accessible PDF/UA and accessible HTML5?
MoreSoftware “tags” documents automatically
As CCM experts, we help our customers convert documents into accessible PDF files. The solution developed by Compart not only automatically tags newly created documents, but also existing documents from archives.
PDF/UA documents and test criteria
The PDF Association has clearly defined the requirements for the PDF/UA standard. With the Matterhorn Protocol 1.1, it has also published a binding test catalog for accessible PDF documents and forms. It contains 136 error criteria in 31 test groups.
Minimum requirements for accessible PDF/UA documents
The ISO standard for PDF/UA describes precise rules for accessible PDF files. The minimum requirements include:
- Documents are classified according to content and meaningless artifacts
- Content must be provided with semantically suitable tags (standard PDF 1.7 tags) and added to a coherent document structure tree
- Artifacts are only to be provided with a tag
- The logical reading order must be reflected in the structure tree
- Images or other graphic elements must be described with an alternative text

The product page for document creation describes how users can easily create legally compliant PDF/UAs.
Strategies for the conversion of existing documents
Making historically grown documents from archives accessible will be a particular challenge. This is because many were created without taking accessibility standards into account. The aim must be to establish an infrastructure that converts all document types automatically and securely.
