PDF/A-2 Released by ISO


The International Organisation for Standardization released PDF/A-2 for the long-term archiving of electronic documents. PDF/A-2 is based on PDF 1.7, which supports a range of improvements in document technology such as JPEG2000 compression, transparency effects and layers, the embedding of OpenType fonts, and provisions for digital signatures in accordance with the PADeS (PDF Advanced Electronic Signatures) standard. Part two of the standard, according to the article on the Image and Data Manager website, also offers the possibility to embed PDF/A files into PDF/A-2. This allows groups of documents to be archived coherently as individual documents.
