Benefits

• Efficient


• Ideal for all automated processes with PDF output.
  Thanks to the complete automation,
  an efficient and cost-saving creation of
  barrier-free documents is achieved.




• Scalable


• With a template-based solution such as axesFlip,
  the amount of documents is fully scalable on
  the customer side and can be adapted to
  a wide range of requirements.




• Versatile use


• axesFlip saves time and money:
  Your templates are tailored exactly to
  the specific needs of your organization.

Each document template can be flexibly expanded
and covers a variety of similar PDF documents;
so you need fewer templates to achieve more.





• Legally compliant


• High-quality accessible documents are
  created with axesFlip within a very short time.

You will achieve legally compliant accessibility
requirements for automated PDF documents
without changing your existing processes.

axesFlip Designer is a stand-alone program that
runs on any standard Windows PC to:

• analyze your PDF documents, and


• create a template (a text file) in JSON format.

The JSON is generated by axesFlip Designer
and displayed in a user-friendly interface.

The template describes the elements of the PDF document
(logo, body text, tables, etc.) in all their complexity.

The axesFlip Designer displays various types of errors,
such as syntax errors when entering code.
It is not a full-fledged debugger, but there is
no need for a debugger in the context of axesFlip.

Requirements on operator of axesFlip Designer:
The basic requirements are logical and structured
thinking as well as good knowledge in the field of
accessible PDF documents.

Software development skills (such as JavaScript or C#)
are not necessary.
The level of requirements is roughly comparable to
someone who is an Excel power user and can write
complex formulas in Excel.

Training materials and advice
can be provided upon request.

axesFlip Worker requires high throughput,
so a Windows or Linux server is recommended.
For very high throughput requirements,
multiple servers can also be parallelized.

The axesFlip Worker is an execution engine
that takes two inputs:

• a non-accessible PDF document
  (as a file or a stream)


• a template authored with the axesFlip Designer

With this as input, the axesFlip Worker converts
non-accessible PDF documents to accessible PDFs
that are fully WCAG and PDF/UA compliant;
cleanly tagged, readable by assistive technologies
such as screen readers, and of the highest quality.

You have several options for running
axesFlip Worker in your system environment:

• as a Command Line Interface (CLI)


• as a REST Service


• as an SDK integrated in your custom software

axesFlip Worker is designed to batch-convert
thousands of similar PDFs in a row.
axesFlip reaches a performance of
dozens to hundreds of pages per second,
depending on the complexity of the PDF document.

The architecture of axesFlip that combines proven
axes4 building blocks with new components.

The core of axesFlip consists of three main parts:

• the technical analysis and processing of
  PDF documents (as in axesPDF).


• the basic architecture for so called
  nodes (feature elements) that
  can be concatenated into a graph.

  Nodes with various functions such as
  element selection, sorting or tagging
  are available or can easily be added
  without changing the architecture.



• a custom expression language that
  allows you to capture PDF objects
  in a simple and effective way.

The expression language is
flexible, powerful and targeted
at its specific use case.

• axesFlip is designed for documents that have
  a similar layout but different content
  (e.g., a bank statement).
  axesFlip is not suitable for static documents,
  which are better tagged manually only once.

Since forms are static,
they are not a use case for axesFlip.



• axesFlip can correctly tag layout tables and
  handle dynamic content elements such as inserts.
  Even in complex scenarios, such as serial documents
  where customer A receives an insert and customer B
  does not, axesFlip processes all variants
  reliably and without barriers.

Elements in a PDF document can be
selected dynamically (e.g. depending on their
relative position to other elements).



• axesFlip can tag complex documents
  (e.g. tables, lists or combinations thereof)
  completely and technically correctly.

axesFlip can, for example,
tag tables correctly regardless of
whether they have 4 or 40 lines.



• Images and graphics can be marked in axesFlip
  and tagged accordingly (typically as "Figure").



• Templates can be created efficiently and flexibly
  using the node graph and the expression language.

Thanks to its innovative technology,
axesFlip is particularly flexible
when it comes to layout variations.

As a guideline,
anything that is perceived by a person as
having the “same” layout can be processed
using same template.

With a single template, many types of documents
can be made accessible. Quotes, order confirmations,
invoices, credit notes, reminders, in several languages,
share often the same basic layout,
but differ in terms of their title and a few other details
and therefore can have a single template.

A bank statement and a loan application
look completely different and therefore require
two different templates.



• axesFlip does not currently support MathML.
  However, axesFlip has an architecture that allows
  new components to be added easily and flexibly.
  If the need arises, a MathML node can be added.

Furthermore, it is unlikely that formulas will appear
as dynamic content in serial documents.
Static formulas can be tagged as formulas with axesFlip.
