doclicense and pdfmanagement

[u-fischer]

The newest pdfmanagement-testphase version no longer contains a patch for hyperxmp. Instead it uses its own code to add xmp-metadata. The loading of hyperxmp is suppressed as the package is incompatible.

doclicense should therefore not assume that hyperref is loaded through hyperxmp but load it itself.

\DocumentMetadata{%
  testphase=phase-II,
  uncompress,
  lang=en-US,
  pdfstandard=a-2u}

\documentclass{article}

%\IfDocumentMetadataTF{\usepackage{hyperref}}{} %load hyperref is pdfmanagement is used

\usepackage[type={CC},modifier={by-nc-nd},version={4.0},lang={english}]{doclicense}

doclicense should therefore not assume that hyperref is loaded through hyperxmp but load it itself.

Does it really assume that? When I look at the code

latex-packages/doclicense/doclicense.dtx

Lines 695 to 729 in 4bb0436

	\AtEndPreamble{%
	\@ifpackageloaded{ccicons}{}{\RequirePackage{ccicons}}
	% For \doclicenseIcon
	\@ifpackageloaded{graphicx}{}{\RequirePackage{graphicx}}
	% For \doclicenseImage
	\@ifpackageloaded{hyperref}{}{\RequirePackage{hyperref}}
	\@ifpackageloaded{csquotes}{%
	% csquotes has already been loaded so we are fine.
	}{%
	\ifcsdef{enquote}{%
	% \enquote is defined but not by csquotes.
	\@ifpackageloaded{biblatex}{%
	\PackageError{doclicense}{The enquote macro is defined by biblatex}
	{This package assumes that the enquote macro is defined by the
	csquotes package. Please load csquotes before you load biblatex so
	that biblatex does not define enquote instead.}%
	}{%
	\PackageError{doclicense}{The enquote macro is defined by an unknown package}
	{This package assumes that the enquote macro is defined by the
	csquotes package. Please check why enquote is defined without
	csquotes being loaded. Maybe try loading csquotes early so that it
	can define the enquote macro instead.}%
	}
	}{%
	\RequirePackage{csquotes}
	}
	}
	\@ifpackageloaded{hyperxmp}{%
	% The following options are only defined when the hyperxmp package was loaded.
	\hypersetup{%
	pdfcopyright = {\doclicenseLongTextForHyperref},
	pdflicenseurl = {\doclicenseURL},
	}
	}{}
	}

both packages are loaded independently by doclicense if they were not loaded at the end of the preamble.

Can you propose a patch/pull request that fixes it for you? I currently don’t have the latest TeX Live installed so I cannot test your example.

sorry I got a bit lost in your various if-clauses and so tried to fix the problem it the wrong way. I will update the pdfmanagement to remove the error there.

But it remains the problem that hyperxmp is not loaded and so your hypersetup is lost. I suggest that you replace

  \@ifpackageloaded{hyperxmp}{%
    % The following options are only defined when the hyperxmp package was loaded.
    \hypersetup{%
      pdfcopyright  = {\doclicenseLongTextForHyperref},
      pdflicenseurl = {\doclicenseURL},
    }
  }{}

\IfDocumentMetadataTF
 {
    \hypersetup{%
      pdfcopyright  = {\doclicenseLongTextForHyperref},
      pdflicenseurl = {\doclicenseURL},
    }
 }
 {
   \@ifpackageloaded{hyperxmp}{%
    \hypersetup{%
      pdfcopyright  = {\doclicenseLongTextForHyperref},
      pdflicenseurl = {\doclicenseURL},
    }}{}
 }
