Determine if the Document is Tagged-2

 

Reveal the Tags Panel

 

There are two ways to accomplish this:

Check Document Properties Tags

This option is the most efficient way to check for tags. Document Properties can also indicate if the PDF is tagged.  

Anywhere on the PDF, right-click > Document Properties. Alternatively, on the keyboard:CTRL (for Windows) or CMD (for Mac) + DApplication - Source Document

To view the original program from which the document was created, look for "Application";  this displays the source program.  In the following example, the original program used is Word.  This information is very helpful, as we now know the PDF document can be easily converted into a Word doc, where all the accessibility principles can be applied in an environment that is far easier than in Adobe Acrobat Pro DC.  Of course, this solution may not work for all documents.

Document Properties can share information about source document and if the document it tagged.

Use the Tags Panel to view tags

To open the Tags panel, select View > Show/Hide > Navigation Panes >Tags.Examine the Tags panel.A tagged document will show tags and a structure tree descending from the root node. To fully expand the entire tree, Control + click on the root node labeled “Tags” (See “Figure 12. Tags Panel Structure Tree Showing Tags”).  An untagged document will display the words “No Tags Available” as its root and no structure tree will appear (See “Figure 13. Tags Panel with No Tags Available”).
