pdfaPilot

Archival

Enterprise PDF processing

callas pdfaPilot is a flexible and highly customizable PDF checking and correction engine ready to be built into larger solutions as background PDF service. It was explicitly conceived for use in the long-term archival and accessibility markets or for enterprise solutions. Even though that is its primary focus, it still supports all of the print-oriented functionality found in callas pdfToolbox.

pdfaPilot can be integrated in many ways (using hot folders, command-line, a full SDK, ReST API…, etc.), runs on most—if not all—modern operating systems, and has modest system requirements. Some of the most important features are described below, but the technology is so flexible that many other PDF-related workflow tasks can also be automated with it. If your need isn’t covered here, contact us so we can evaluate the best way to accomplish what you need.

Features

Support for archival workflows

callas actively participates in the ISO committees working on the PDF/A standard for long-term archival using PDF. As a result, all different versions and flavors of the PDF/A standard are fully supported by pdfaPilot. It can check whether PDF files comply with the standard or convert incoming PDF files to PDF/A.

Such conversions can be done with minimal to no quality loss for PDF files where possible, but fallback mechanisms can be used to ensure the highest possible percentage of PDF files are converted into PDF/A.

Accessibility

More and more legislation requires PDF files to be accessible. In most cases, this means that the PDF must comply with the PDF/UA (which stands for PDF for Universal Accessibility) ISO standard. pdfaPilot can verify that a PDF is compliant to the PDF/UA standard for those aspects that are machine-verifiable.

Additionally, pdfaPilot integrates technology that converts tagged PDF files into HTML with different visualizations of the structure and tagging present in the PDF file. This is designed to facilitate human verification of the quality of the structure and tagging in the tagged PDF file.

Email conversion

pdfaPilot has integrated “email-to-PDF” functionality that takes common email file formats and converts them into standards-compliant PDF/A files. The advantages of the technology are that the template used to represent the email in PDF is fully customizable (and thus can be adapted to specific workflows or use cases), and that pdfaPilot offers a variety of options on how to handle email attachments. Using PDF/A-2 or PDF/A-3, the attachments are embedded in their original format and/or converted into PDF/A.

Electronic invoicing

pdfaPilot has supported the German ZugFeRD electronic invoice standard from the very beginning. It could create a ZuGFeRD invoice from an XML and PDF version of the invoice, verify compliance of an existing electronic invoice, or extract the XML component from it for further processing. With the electronic invoicing initiative being picked up as a European standard, pdfaPilot still supports handling such documents.
