How to generate a PDF/A-3b document with LuaLaTeX?

Question

I want to convert my document to PDF/A-3b. I'm using lualatex and I have a custom font if that matters. I've tried setting the pdf attributes with hyperref, but that appears to not be enough. How do I go about doing that?

You can try with the new pdfmanagement of LaTeX. It creates xmp-metadata. hyperxmp is not compatible anymore and should not be used.

\DocumentMetadata{pdfstandard=A-3b}
\documentclass{article}
\usepackage{hyperref}
\hypersetup{pdftitle=test,pdfauthor=me}
\begin{document}
some text
\end{document}

Be aware that "testphase" means that this in the testphase and not every package is already compatible. Check the documentation if needed.

Answer 2

LaTeXcan't produce PDF/A out of the box. You either need to use the pdfx or the hyperxmp package. pdfx is meant as the all-in-one solutions for all kind of PDF varieties, but it's rather fragile, so hyperxmp might be the better solution.

Check out PDF/A with hyperref on TeX Live 2013 and PDF/A with CMYK, how? for some hints how to go about this.
