The goal of the GNU PDF project is to develop and provide a free, high-quality and fully functional set of libraries and programs that implement the PDF file format, and associated technologies.
We are working to implement support for the following technologies and specs:
* PDF 1.7
* PDF/A-1 (ISO 19005-1:2005)
* Extensible Metadata Platform (XMP)
* XML Forms Architecture v2.4 (XFA)
