Accessible and Tagged PDF
2021-03-10 · via Jonathan Fine

Accessible PDF

A PDF document is accessible to me if I can open and read it. That might depend on the circumstances and the document. It is a human-related property of the document. A real human being reading the document.

Tagged PDF

A PDF document is tagged if roughly speaking from it an equivalent HTML document can be obtained, by applying some technically specified software. The real human being reading the document is not present.

Suppose a person with a disability tries to read a tagged PDF document. If they succeed, the PDF is accessible to them. If they fail then it is not.

To be a tagged PDF is a technical question. To be an accessible PDF is a human question. Let's not confuse the two concepts.

Does it have to be a PDF that the person reads? Perhaps accessible HTML is both easier to produce and easier to read.

We all have habits

Software engineers see many problems as being technical. Politicians see many problems as being political. Teacher tend to see many problems are educational. And so on. They are all correct to some degree.

A LaTeX developer might hope that adding tags to a PDF document would make it accessible. But that outcome is not certain. And certainly expensive. At least 2 persons working for 4 year, according to this document (PDF)

Perhaps HTML would be better.

The law of the instrument

According to Abraham Maslow's Law of the instrument

it is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail.
