Is it possible to create PDF's that have a level 1 compliance with the PDF/A ISO standard? The website doesn't mention support for the standard at all. But it's crucial to my decision to use Prince as a PDF generator.
Last time I checked, PDF documents created by Prince were almost but not quite compatible. Do you have Acrobat Professional installed? It can tell you if a PDF complies with various profiles of the spec, and if not, what needs to be changed.
I don't have Acrobat installed. But fixing the issues that Acrobat mentions would not be a bullet proof approach to ensure that all PDF's generated by Prince are PDF/A-1a compliant, right? Some incompatibilities might be content driven.
True, the only guaranteed solution is to study the specification in detail then add a new command-line argument to Prince to force compliance with the spec, which might require rejecting some input documents depending on their content.
Does your customer specifically require PDF/A-1a, and not just PDF/A-1b? This will require us to support tagged PDF in Prince, which is definitely on the roadmap, but isn't likely to see daylight before next year.
Our roadmap is flexible, and we like a challenge. Perhaps we can take this over to email (firstname.lastname@example.org) and discuss what kind of documents you need to convert, and how much work it will take for us to support them.
I'm very interested in this too. Danish government has made an agreement with local governments that all non-editable documents published on web sites and sent to citizens and companies should be distributed in PDF/a1 - ref (in Danish): http://vtu.dk/filer/aabne-standarder/bilag58.html).
We are evaluating different PDF renderers for governmental clients and it would be a shame to settle with less visual appealing PDF's than those Prince XML can generate in order to comply with this.
