Apache OpenOffice (AOO) Bugzilla – Issue 122033
Support for PDF/A-2 (ISO 19005-2:2011)
Last modified: 2023-08-21 14:51:14 UTC
PDF/A is widely used for long-term preservation of documents. For example many governments (a.o. European, Austrian, Dutch, Brazilian, German, Swiss) recommend or mandate PDF/A. Apache OpenOffice already supports exports to PDF/A-1, which is great. PDF/A-2 is the second part to the standard. It adds some significant extra features. Therefore it is important that Apache OpenOffice will support PDF/A-2. In the below you will find some basic information on PDF/A-2 from Wikipedia and some pointers to more background information. --- PDF/A-2 address some of the new features added with versions 1.5, 1.6 and 1.7 of the PDF Reference. PDF/A-2 should be backwards compatible, i.e. all valid PDF/A-1 documents should also be compliant with PDF/A-2. However PDF/A-2 compliant files will not necessarily be PDF/A-1 compliant. Part 2 of the PDF/A Standard is based on a more recent version, PDF 1.7 (ISO 32000-1), rather than PDF 1.4 and offers a number of new features: * JPEG2000 image compression * support for transparency effects and layers * embedding of OpenType fonts * provisions for digital signatures in accordance with the PDF Advanced Electronic Signatures – PAdES standard * possibility to embed PDF/A files in PDF/A-2 for archiving of sets of documents as individual documents in a single file.[5] Part 2 defines three conformance levels: PDF/A-2a, PDF/A-2b and a new conformance level PDF/A-2u. PDF/A-2u represents Level B conformance (PDF/A-2b) with the additional requirement that all text in the document have Unicode mapping. --- Background information: - http://en.wikipedia.org/wiki/PDF/A#PDF.2FA-2 - http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=50655 - http://www.digitalpreservation.gov/formats/fdd/fdd000319.shtml - http://www.scl.org/site.aspx?i=xb965

In the same way, AOO should support PDF/A-3 too. This is necessary to make invoices in CII format (Factur-X) https://tfig.unece.org/contents/cross-industry-invoice-cii.htm
Maybe we should think about using something like Poppler to support these functionalities. https://poppler.freedesktop.org/
