Hi Phill,


Thank you for the useful suggestions.


The customer I am currently assisting has multiple lines of business. It
appears to me that the different needs of these entities impacts whether web
designers use fillable PDF files displayed in-line or whether they allow for
the referencing of a PDF (downloadable) via link to a PDF file in a
repository from a web page.

Subject: Re: PDF's Exposed via Web Pages and Accessibility


can you comment a little more about your use of the term " embedding PDF
files in web pages"?   
I assume you mean "not attaching them", or otherwise making them available
to be detached, downloaded, printed, etc. But embedded as in "displayed
in-line" with a PDF browser plug-in? 

>From a software architecture perspective, there are several considerations
or requirements, but not that many "best practices" other than my list

Possible Courses of Action: 
Identified are a set of possible courses of action that need to be
considered when developing a remediation plan for making PDFs accessible
with a sustainable approach.  Depending on the type of issues found and the
type of PDF itself (e.g. data tables and/or interactive forms) the
enterprise can take one or more of the following possible courses of action:

1.        Alternative format - strongly consider providing an alternative
format of the same information at the same availability.  For example, for
PDFs that contains a data table, consider providing a spreadsheet equivalent
in CSV or Microsoft Excel format of the same data, and provide it
dynamically on-demand when that is how the PDF is provided.  Another example
is to provide a more mobile friendly accessible e-Pub 3 or a desktop HTML 5
version of the information with an appropriate CSS style sheet for printing.

2.        Repair the back-end system - consider repairing the back-end
system that collects the information and dynamically creates the PDF.  For
example, do an analysis of the original source data, PDF templates, XML
schemas and any transformation systems that created the dynamic PDF to
identify repair options and requirements.  This will often require working
with the back-end system owner (software developer or vendor). 
3.        Repair the PDF - Assess and remediate the PDF and replace it for
future downloading or reference.  For example, a single annual company
report may simply be repaired once and then replaces the previous
inaccessible version. 
4.        Repair on-demand - Upon request, assess and repair the PDF
document.  This course of action will often require educating the customer
help desk with procedures on how to respond to customer request, often
require adding end-user information on how to request a repaired PDF, and a
responsive repair procedure that is acceptable to end-user expectations. The
on-demand option could also be out-sourced to a 3rd party service provider
with appropriate turn-around times expectations set. . 
5.        Replace the back-end system - replace the back-end system with one
that is capable of creating accessible PDFs.  Conduct an assessment of the
system, including original source data, PDF templates, XML schemas and any
transformation systems that creates the PDF to ensure it will meet
accessibility standards.  Commercial back-end systems are available for
comparisons and assessment of applicability to the enterprise's
6.        Establish the back-end creation process, tools,  and procedures -
replace the process, tools,  and procedures that are used to create the
original PDF.  For example, provide training and software wizards that guide
the original author to make or output accessible PDFs for original source
systems such as Microsoft Office Word and PowerPoint.  Often this course of
action will also require a periodic audit of PDF attachments to determine if
the process and procedures are being followed and that only accessible PDFs
are being posted to the website.     
7.        Patch the back-end system - repair part of the back-end system by
intercepting the PDF content during the workflow and redirect the output to
a transformation system that can convert/repair the PDF before the final PDF
is posted for end users to download.  For example, work with a 3rd party
service provider that specializes in back-end PDF remediation. 
8.        Remove - Assess the value or need of keeping inaccessible PDF
available and remove the ones that are no longer needed. 

Combination - Some appropriate combination of the above possible courses of
action.  Often this approach is used across an enterprise where different
back-end process, procedures, and systems are used (for example by line of
business), each requiring a different course of action.  Often an enterprise
wide as-is assessment along with a strategy and roadmap will be the most
efficient and effective course of action for the enterprise..

Subject:        PDF's Exposed via Web Pages and Accessibility 


I am currently working on a Customer Communications Management architecture
project for a financial services firm. One of the issues I have been asked
to investigate, from an architectural perspective, is the use of PDF files
embedded within a publicly available web page. 
I have been reviewing the proposed refresh of the United States of America
Section 508 regulation, which specifically calls out using PDF/UA when
embedding PDF files into web pages:
In looking at this issue from an architectural perspective, it seems like
placing some form of validator in the delivery channels from PDF creator to
web page delivery would likely be necessary to insure all PDF's made
available for web page deployment were PDF/UA compliant. 
I am hoping that subscribers to this W3C list with experience in this area
might be able to comment on best practices for embedding PDF files in web
pages and maintaining accessibility conformance (Examples: WCAG 2.0 and the
ISO Standard known as PDF/UA) going forward.
