Frequently asked questions (FAQ)
Is axesFlip GDPR compliant?
Yes, axesFlip is fully GDPR compliant and meets all legal requirements for data protection and accessibility.
Is a server required for the on-site installation of axesFlip?
axesFlip consists of two parts, the Designer and the Worker.
- The designer runs on any standard Windows desktop PC.
- The worker requires high throughput, so a Windows or Linux server is recommended. For very high throughput requirements, multiple servers can also be parallelized.
Which platforms does the axesFlip Worker support?
The axesFlip Worker supports Windows and Linux. A powerful server is recommended for operation, as the worker is designed for high throughput.
What is the minimum volume for which the solution is suitable?
There are two aspects to consider:
- axesFlip runs on the customer's servers, which involves preparation and installation work.
- Template creation involves training and development costs.
That is why we give a guideline figure of approximately 20,000 documents per year.
Is a manual review of PDF accessibility necessary?
It is always advisable to check at least some of the documents, not because axesFlip is unreliable, but because certain variations in the series documents may have been overlooked when creating the template.
We offer axesSense for automatic testing.
Alternatively, documents can be checked manually in PAC on a random basis.
What requirements and knowledge does a person need to create templates with 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.
axes4 provides training materials and is happy to offer advice.
What does a template look like?
Technically, a template is a text file in JSON format. However, users do not come into contact with this format. The JSON is generated by axesFlip Designer and displayed in a user-friendly interface.
When do I need a new template for a document?
As a guideline, anything that is perceived by a person as having the “same” layout can be processed using a template.
Examples:
- A quote, an order confirmation, an invoice, and a credit note that share the same basic layout but differ in terms of their title and a few other details have a single template.
- A bank statement and a loan application look completely different and therefore require two different templates.
Thanks to its innovative technology, axesFlip is particularly flexible when it comes to layout variations.
Will axesFlip help me create templates?
Yes, absolutely. axesFlip Designer was developed specifically to make creating templates as easy and efficient as possible. You work in an intuitive user interface that guides you step by step through the process, without any direct contact with the technical JSON format.
Is axesFlip necessary if accessible PDF documents can be created directly in a workflow?
No, axesFlip is designed for a workflow in which non-accessible documents are created.
If software can create accessible PDF documents directly, that is the preferred method. axes4 can provide advice on this (for example, with axesSense to check whether the documents are truly accessible).
Is there a debugger for errors when entering code in axesFlip Designer?
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 one in the context of axesFlip.
Can axesFlip handle complex document structures, including layout tables and dynamic content parts such as inserts?
Yes, 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.
How are images or graphics handled in axesFlip?
Images and graphics can be marked in axesFlip and tagged accordingly (typically Figure).
Does axesFlip work with interactive forms in PDF?
axesFlip is designed for documents that have a similar layout but different content (e.g., a bank statement). It is not suitable for static documents, which are better tagged manually once.
Since forms are static, they are not a use case for axesFlip.
How does axesFlip work with formulas? Can it handle MathML?
axesFlip does not currently support MathML. However, it has an architecture that allows new components to be added easily and flexibly. If the need arises, we can add a MathML node.
Furthermore, it is unlikely that formulas will appear as dynamic content in serial documents. Static formulas can be tagged as formulas with axesFlip.
