Dear list, (especially Luigi) for online publication I need to create a PDF/A compliant output file. Does anyone have any experience with it and can tell me whether my setup will work? So far I'm using \setupbackend [ format={pdf/a-2a}, profile={default_cmyk.icc,default_rgb.icc,default_gray.icc}, ] \setupstructure[state=start,method=auto] I chose PDF/A-2a because there I can have PDF 1.7 which keeps the file size down but I can also switch to PDF/A-1a. I have *no* external pixel graphics, just included PDFs which are also produced by ConTeXt with the same setup. Online I found Luigi's paper on PDF/A-1a [1]. However, even after reading I'm unsure whether `intent` is optional or required. Since I don't own Adobe Acrobat (nor am I using Windows) I cannot verify the resulting output. Does anyone know any working free or open-source tools for GNU/Linux to do this task? Cheers, Henri [1] http://www.ntg.nl/maps/41/08.pdf
