PDF/A is designed to do much in this area: It saves the look and searchability of the original file, and it requires that the original fonts, colors, and layout be preserved in the PDF/A you produce. The goal of any conversion program, even microfilming and scanning, is to create a new record that is as much like the original as possible. PDF/A is specifically designed to support rich metadata. For digital files, metadata is often stored within the file itself, so it is important to be able to save this metadata (and even add to it) when converting one digital file to another. This metadata can include many pieces of information, such as the name of the author and the date of a file. To understand a digital file, you often need good metadata to give context to the file.

Again, so long as PDF is around, PDF/As will be easy to read and use. The PDF format has been around since 1991, so this format is unlikely to disappear soon.

Adobe distributes for free Adobe Reader software for reading PDFs, allowing everyone to read a PDF/A at no additional cost in computing equipment or hardware. Also, since PDF/A is merely a subset of PDF, any software product that can read a PDF can read a PDF/A. The value of this universal use of PDF is that this means it is unlikely to die out as a format anytime soon. Something ubiquitous is something that you can find everywhere, and the PDF and PDF/A formats are used by hundreds of millions of people across the world every day.

What this means is that a PDF/A created in a Windows environment will be perfectly readable and usable in a Mac environment, or vice versa. Since its inception, the PDF format has been accessible across computing platforms, and the PDF/A format has this same advantage. Microsoft Word, for instance, is ubiquitous and long-lived, but it is missing other essential features that would make it a candidate for long-term storage of records. Note that you will find file formats that have one or even a few of these advantages, but it is the accumulation of these that makes PDF/A a good preservation format.

The advantages of PDF/A given below will serve as a checklist of features necessary in any preservation format. If you are considering other digital file formats as options for long-term or permanent storage, compare their advantages to those of PDF/A. PDF/A has many advantages as a file format for the storage of records with long or permanent retention periods. (See the State Archives’ 2013 Digital Imaging Guidelines for the guidelines for scanning and OCR’ing textual documents.) Advantages of PDF/A Whenever you OCR a document, however, there will be data errors in the converted text. Paper documents can also be converted to PDF/A during scanning, but if doing so it will be best if you also use optical character recognition (OCR) software to convert the images of letters in the document into electronic text. It is not appropriate for files that are always in flux, such as databases. The format works best for static files that do not change. Any digital file that can be printed can be converted to a PDF/A, though this format is better for some documents than others. You could even convert a sequence of digital images into one PDF/A. Other digital files may also be converted to PDF/A, including regular PDFs, email, digital images, and spreadsheets. For these reasons, PDF/A is a good format in cases where the appearance of the document matters to interpretation and understanding it. If the document is in color, the color is still there as well. Each page of the original document appears as a single page in the preservation file, the same fonts are used in both documents, and you can search the text of the PDF/A just as you had in the original. When you convert such a file into a PDF/A, the resulting file retains the look and feel of the original document. PDF/A can be used to store many types of records, but it is most valuable as a format for storing long-term copies of digital textual documents, such as Microsoft Word files. One of the great values of PDF formats is that they are open standards, used widely across the world, and designed to record both images and machine-readable text in one document. It is an international standard and a subset of the PDF format.

The format, though, can also be used for scanned documents.

The PDF/A (or Portable Document Format Archival) is a format designed as a preservation format for digital records, particularly documents.
