Hi everyone!

I am remediating PDFs and I was wondering if there is a recommended
structure for organizing tags? I know that you can actually name them, and
I have when tagging a table by hand, but is there an actual industry
standard? I've checked W3 but the only thing I've found is this article
about PDF techniques for WCAG 2.0
<https://www.w3.org/TR/WCAG20-TECHS/pdf#PDF2>.

I have been using a method when I name every tag by page number and in what
order it appears in the document.

Example:

(This is what my tags panel inside the Accessibility tool looks like in one
document)

[Tags]
[<Part> Chapter 5]
indent [<Sect> Page 12]
indent indent [<H1> 12.1]
indent indent [<H2> 12.2]
indent indent [<P> 12.3]
indent indent [<P> 12.4]
indent [<Sect> Page 13]
indent indent [<P>13.1]
indent indent [<P> 13.2]

End example

I think this system should work for most articles and things that I work
on, but I probably will encounter something that completely negates this.

Hi Laurie, the Tagged PDF Best Practice Guide: Syntax Document<https://www.pdfa.org/wp-content/uploads/2019/06/TaggedPDFBestPracticeGuideSyntax.pdf> from the PDF Association give some information about structure and grouping. In terms of titles for tags - I suggest picking something that works best for you to help you understand what is covered without having to expand the elements. Titles might also be helpful to someone else who you are working with to remediate or someone who might come after you to remove the tags tree to quickly locate portions of the document. I find that when element highlight is on in large documents and tags have to be expanded Acrobat can be slow - so naming can help you quickly jump around without having to use the highlight feature or expand the tag. The title's won't be visible to users of assistive technology when reading a document though - but they would be visible to anyone who looked in the tags structure - so be mindful of comments.

Building on Jonathan's comments, the grouping tags are used like this
example:

Tags
<Document> Should encase all of the tags in the entire document
<Art> Which is an article, not artwork.
Should group an entire story, from its heading to
the end.
<Hx>
<P>
Followed by more regular element tags, <L>, <Table>
and others.
<Sect> A small section of content related to the
article/story.
Common example is a sidebar to a story.

The <Part> tag is for a major section of a large document. Examples: a
chapter of a book, a department in a magazine.

<Div> is not well defined in PDF/UA and is not recognized by AT, so we don't
recommend its use in most PDFs.
