The PDF/A standard does not define an archiving strategy or the goals of an archiving system. This need exists in a wide variety of government, industry and academic areas worldwide, including legal systems, libraries, newspapers, and regulated industries.
PDF ATTRIBUTES A VS AT ARCHIVE
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. PDF/A was originally a new joint activity between the Association for Suppliers of Printing, Publishing and Converting Technologies ( NPES) and the Association for Information and Image Management AIIM in conjunction with Adobe to develop an international standard defining the use of the Portable Document Format (PDF) for archiving documents.

However, the suitability of a PDF file for archival preservation depends on options chosen when the PDF is created: most notably, whether to embed the necessary fonts for rendering the document whether to use encryption and whether to preserve additional information from the original document beyond what is needed to print it. PDF is a standard for encoding documents in an "as printed" form that is portable between systems. Part 3: Use of ISO 32000-1 with support for embedded files
PDF 1.4 ( Adobe Systems, PDF Reference, third edition) Standards ISO 19005 – Document management – Electronic document file format for long-term preservation (PDF/A) The ISO requirements for PDF/A file viewers include color management guidelines, support for embedded fonts, and a user interface for reading embedded annotations. PDF/A differs from PDF by prohibiting features unsuitable for long-term archiving, such as font linking (as opposed to font embedding) and encryption.
PDF/A is an ISO-standardized version of the Portable Document Format (PDF) specialized for use in the archiving and long-term preservation of electronic documents.
