Various standards have different requirements for tagging Notes. Of course, there are additional things to consider. The text of the footnote is placed in a Span tag. Ordinarily, the number is placed in a Label (Lbl) tag. A Note tag contains it all, but there may be sub-structures inside. Tagging the note itself, what the reference points to, has several parts. Notice that the Reference tag is in the Paragraph tag with the rest of the paragraph’s text. The superscript number 2 is highlighted at the end of a paragraph in the physical view. The screenshot below shows a Reference tag in the Tags tree with the number 2 inside it. In each instance of a footnote or endnote, the superscript number is placed within a Reference tag. Endnotes show up at the end of the document. For footnotes, the second part is the note itself, which appears at the bottom of the page. The first part is the superscript number in the main body of the document.
There are two separate components to tagging footnotes or endnotes. Likewise, the main body of the document can be a paragraph, list or table, though we will primarily use paragraph in this article.
The guidance and suggestions offered in this article are for version 1 of the PDF standard (ISO 32000) and version 1 of PDF/UA.This article provides guidance on tagging and offers suggestions and options to consider when determining the tags’ reading order in the Tags tree. A question that often comes up in our PDF remediation classes is, “how do you tag footnotes or endnotes?”
