adding links - out of tree structure

I have a Word 2007 document with a TOC and converted to acrobat 9. The TOC has page view links so that the user can jump to the different content pages. When I converted to PDF that links were gone but the links in the footnotes were there.

when I went to add a link in the TOC it works fine. When I check with the Accessibiity checker it says it is outside the tree structure. When I look at the Tag it is still a 'reference' tag instead of a 'link'. Anyway to resolve this? As a point, it must pass the accessibility checker to be accepted.

thx

Hi,

From Adobe Accesible PDF documentation:

Quote:
Adding Accessible Links (to a PDF)–Acrobat provides several ways to create active links for text, objects, and URLs in a PDF document.
However, because the methods differ in how they affect the tag tree,
Adobe recommends only one method at this stage in the workflow:
activating each link manually by using the Create Link command.

Unlike the other methods for creating links in a tagged PDF document
(by using the Links tool or the Create From URLs In Document command),
using the Create Link command adds all three tags that screen readers require in order to recognize a link.
The other methods create only one of the three tags, which means that you must manually edit the tag tree
to add the remaining two tags for each link and place these tags in the proper reading order in the tree.
Although you must activate links one by one, using the Create Link command provides the fastest results
and the least amount of follow-up work to make the links accessible to screen readers.
All that you need to do afterward is edti the tag tree to add alternate text to the new links, if desired.

You must use Acrobat Professional to perform this accessibility task, and to add alternate text to links.
Creating links by using Acrobat Standard does not generate any tags for the links.

thx, this has been very helpful. The issue now is that 3/4 of the links pass but about a 1/4 of them come up as inaccessible link. I deleted the link and started over followed the procedure again and still end up with inaccessible link. Very frustrating, any ideas how to resolve this issue.

thx again

Hi,

You may need to clean out the structure tree.
Open a testing copy of the PDF the the first PDF page.
Open the Tags panel and then the Options menu (drop-down with cog-wheel icon).
Click on 'Highlight Content'.
Back into the Options menu, click on 'Find'.
In the Find Element dialog, select 'Unmarked Links'.
Make note of any found.
These would be the Link element(s) that contribute to a Full Check (Adobe PDF) identifing
<... element(s) that are not contained within the structure tree.>Similarly, run 'Find' for Unmarked Comments or Annotations if you have used these.
Run 'Find' for Unmarked Content.
Remember, this will also locate Artifacts; so, be aware of what you've decided are supposed to be Artifacts. Anything else is contributing to
<... element(s) that are not contained within the structure tree.>You can add a Tag for Unmarked Content while in the Find Element dialog but 'Create Tag from Selection' may be better.
In the Tag panel, select the desired parent element.
Now use the Select tool to select the content on the PDF page.
Back to the Tags panel Option menu; select 'Create Tag from Selection'.
A container icon will appear as a child to the element (tag) you had selected in the Tags panel.

As you clean up, walk the structure tree to observe the tree/page content alignment.
Fully expand the structure tree in the Tags panel.
From the Options menu, select 'Highlight Content'.
Use the cursor arrow keys to walk down. Left arrow to collapse as desired.
Are tags appropriate to content, in the right order, have a proper hierarchy (nesting), etc.

Just a note re: Full Checker (Adobe PDF) --
While this does check for items necessary for success, it does not check for correct element structure across the board. An example is the <Table> element.
A "layout" table (no <TH> elements) will not be 'flagged' by Full Checker (Adobe PDF).
Lack of an appropriate "header row" with <TH> elements is a non-accessible PDF.
ISO 32000-1, Section 508's 1194.22 paragraphs (g) & (h), WCAG 1.0 (5.1, 5.2), and the release draft to the updated standars and guidelines to correlated to WCAG 2.0 are all rather clear that <TH> is required.

Be well...
