The Digital Preservation Coalition (DPC) and Charles Beagrie Ltd have released Preservation with PDF/A by Betsy Fanning, the latest in their series of Technology Watch Reports to the public. This is now the 14th Technology Watch Report produced over the last 5 years by Charles Beagrie Ltd and the DPC. It provides a comprehensive review of the PDF/A standard and its use.

An update to the original Technology Watch Report, Preserving the Data Explosion: Using PDF published in 2008, the report begins with a history of the PDF/A standard and its development, before moving on to an examination of conformance levels, validation methods and considerations to be made when choosing to use PDF/A for long-term preservation.

“Conformance to the standard is not a simple ‘yes/no’ binary state, in part because there are now four variants of PDF/A,” explains author Betsy Fanning. “One question that is often asked is: ’When should I use PDF/A, and which version should I use?’ This report attempts to answer that question and to provide some guidance about the strengths, weaknesses, opportunities and threats associated with each.”

Preservation with PDF/A examines each of the four variants and lays out the conditions under which it might be beneficial to use PDF/A-3 rather than PDF/A-1, and vice versa, before presenting a range of practical considerations to make the most effective use of the file format.

Neil Beagrie, managing editor of the Technology Watch Report series on behalf of the DPC, added “the choice of file format is a component of a wider technical and organizational infrastructure which comprises a comprehensive digital preservation solution. This report will make interesting reading for anyone putting together their digital preservation strategy.”
