Digital Preservation with Portable Documents: a workshop to introduce and discuss the PDF/A version

Introduction The portable document format (PDF) is ubiquitous, easily-produced and is widely used in a diverse range of environments.  A variant of the standard – PDF/A in which ‘A’ stands for archive – was published in 2005.  This version of the standard, also published as ISO 19005, minimises the dependencies between the contents of a file and the system on which it is rendered.  This self-contained characteristic of PDF/A makes it particularly attractive for those...
