During IS&T 2008 in Bern, LuraTech discussed PDF/A-1, which is the current ISO standard for long-term archiving. Since then, the ISO committee and its Class A liaison member, the PDF/A Competence Center, has been working on the new part of the standard, PDF/A-2 (ISO 19005-2). PDF/A-2 is now in draft international standard (DIS) status and is expected to become an international standard in Fall 2010. This paper presents an overview of PDF/A and describes the new functions of PDF/A-2 with respect to user applications. In addition, we will discuss the current usage of PDF/A in archives and libraries and outline the advantages of PDF/A-2 for these markets.
