Part 1: Use of PDF pdf can only see symbols. PDF is a standard for encoding documents in an “as printed” form that is portable between systems. The goal was to address the growing need to electronically archive documents in a way that would ensure preservation of their contents over an extended period of time and ensure that those documents would be able to be retrieved and rendered with a consistent and predictable result in the future. This need exists in a wide variety of government and industry areas worldwide, including legal systems, libraries, newspapers, and regulated industries.

A standard does not define an archiving strategy or the goals of an archiving system. It identifies a “profile” for electronic documents that ensures the documents can be reproduced exactly the same way using various software in years to come. All of the information necessary for displaying the document in the same manner is embedded in the file. Audio and video content is forbidden. All fonts must be embedded and also must be legally embeddable for unlimited, universal rendering. Colorspaces specified in a device-independent manner.

Use of standards-based metadata is required. External content references are forbidden. A documents in a single file.

A standard, by authors aware of features that present long-term preservation issues. A Competence Center led to the development of the Isartor Test Suite in 2007 and 2008. A-1b conformance, allowing developers to test the ability of their software to validate against the standard’s most basic level of conformance. The veraPDF consortium subsequently won phase 2 of the PREFORMA contract in April 2015. Phase 2 completed on-schedule by December 2016.

A file can be formally correct yet still have incorrect glyphs. Only a careful visual check can uncover this problem.

Because generation problems also affect Unicode mapping, the problem attracts the attention when a visual check is carried out on the extracted text. Meaning that for a document to be completely compliant with the standard, it will be correct internally, while the system used for viewing or printing the document may produce undesired results. A-3 doesn’t support the notdefglyph flag. Therefore, this type of conversion can result in unrendered content. A-2 Standard Published by ISO!
