I'd like to generate a PDF/A-compliant document. Thus I need to embed the metadata using XMP but somehow the following MWE doesn't work.



\Title{My Sample Title} 


How can I fix this and what's up with packages like hyperxmp?

    "does not work" is not an appropriate error message. What is the exact error you get?

    Just move the \newcommand{\Subject}{...} line before \usepackage[a-1b]{pdfx}

  • Well, there isn't any error but the PDF doesn't contain any metadata afterwards. Moving the subject line or leaving out the subject at all doesn't help either.

    Do you have ISOcoated_v2_300_bas.ICC in your computer somewhere? See : Add metadata in pdf as type pdf/a

Your provided example works fine for me. Therefore, I have to assume there is some confusion about the XMP Metadata and/or the process on how to typeset the document.

First of all, XMP metadata is not the PDF metadata, e.g. XMP data can be viewed by using Adobe Acrobat: File, Properties, Additional Metadata; whereas the normal metadata already shows up under file, properties.

Secondly: Do you use pdflatex to create your document?
