    What is a PDF/A?

    Portable Document Format (PDF) files are a handy way to exchange documents with others without requiring them to have a copy of the application that was used to create the original document. PDFs provide a way to view, as well as print, an accurate representation of the original document. The PDF format was around for a number of years and rapidly grew to become a de facto standard. As the use of the PDF format exploded, so did the variations in the format. Not everyone implemented the format in exactly the same way, and not everyone supported every new feature that was added to the format as it evolved. Demand grew for improved standardization as well as a version of a PDF that could be used for long term document archiving. A PDF file format was desired that would assure that documents created using the format would be able to be viewed and displayed at any point in the future – regardless of other changes in the rapidly changing world of computer technology. At the same time, the number of paper documents being stored was rapidly decreasing in favor of electronic document storage. Since many documents form a legal record, it was also important that the content of the original documents be maintained perfectly and were able to be viewed and printed perpetually.

    What is a PDF?

    We all take for granted that everyone knows what a PDF is. But there is a lot more to a PDF than many people realize. PDF stands for “Portable Document Format.” In its most basic form, a PDF is a standardized computer data file format used for exchanging information with others. Because the file format is based on a published standard, it theoretically makes it possible that anyone can open any PDF document as long as the PDF document follows the rules outlined by the standard. The PDF standard is normally referred to as the “PDF specification.” It evolved from a project at Adobe Systems Corporation whose goal was to create a standard format for exchanging documents across diverse computer platforms. Originally, the PDF specification was proprietary to and owned by Adobe, but in later years they released information to the public and relinquished their rights of ownership. Eventually, the International Organization for Standardization (IS0) published a standard for it. The specification has been enhanced over the years to include new features. The first version of the PDF specification was given a 1.0 designation. Subsequent versions of the specification have been developed and named using a version increment of .1 for minor revisions or 1 for major revisions. The current PDF specification version is 1.7. Adobe has complicated the standard by adding its own proprietary extensions with versions numbered using a “Level” numbering scheme. The PDF specifications have been designed so that each version is compatible with all of the previous versions. So PDF documents created using the 1.0 specification can still be displayed by software that implements the 1.7 specification. But the reverse is not true.
