Embed non-PDF files (e.g., BibTex) into PDF with hyperlink in the PDF

Question

This question led to a new package:
intopdf

Aim

I want to achieve following:

1. Embed paper.bib into PDF

2. paper.bib should be opened with the OS tool associated with mimetype application/x-bibtex

3. Have paper.bib listed in the attachment section in Acrobat Reader

   

4. The attachment section should have a proper description

5. Have paper.bib listed in the "\EmbedFiles" in PDF (can be checked with Acrobat Pro)

   

6. Have paper.bib listed in the bookmarks section

   

7. Have a working link to paper.bib in the PDF

   

   

8. Have the link visible also in the printed version

9. No strange additional icon. Following should not appear:

   

10. Link should be marked as link

Tried solutions

1. embedfile together with hypgotoe

\documentclass {article}
\usepackage{mwe}
\usepackage{filecontents}
\usepackage{embedfile}
\usepackage{hypgotoe}

\begin{filecontents}{paper.bib}
@article{demo,
  author={Demo Author}
}
\end{filecontents}

\begin{document}

\embedfile[
  desc={BibTeX entry of this paper},
  mimetype=application/x-bibtex
]{paper.bib}

\href{gotoe:embedded=paper.bib}{BibTeX}

\end{document}

1. YES: Embed paper.bib into PDF
2. YES: paper.bib should be opened with the OS tool associated with mimetype application/x-bibtex
3. YES: Have paper.bib listed in the attachment section in Acrobat Reader
4. YES: The attachment section should have a proper description
5. YES: Have paper.bib listed in the "\EmbedFiles" in PDF
6. Partially: Have paper.bib listed in the bookmarks section (OK: SumatraPDF, NOT OK: Acrobat Pro X)
7. NO: Have a working link to paper.bib in the PDF. SumatraPDF opens the tex file, Acrobat Reader does nothing
8. YES: Have the link visible also in the printed version
9. YES: No strange additional icon
10. YES: Link should be marked as link

2. navigator

\documentclass {article}
\usepackage{mwe}
\usepackage{filecontents}
\usepackage{navigator}

\begin{filecontents}{paper.bib}
@article{demo,
  author={Demo Author}
}
\end{filecontents}

\begin{document}

\embeddedfile[BibTeX entry of this paper]{paper.bib}{paper.bib}

\openfilelink{paper.bib}{BibTeX}

\end{document}

2. YES: paper.bib should be opened with the OS tool associated with mimetype application/x-bibtex
3. YES: Have paper.bib listed in the attachment section in Acrobat Reader
4. YES: The attachment section should have a proper description
5. YES: Have paper.bib listed in the "\EmbedFiles" in PDF
6. NO: Have paper.bib listed in the bookmarks section
7. PARTIALLY: Have a working link to paper.bib in the PDF: Double click opens file in SumatraPDF, not working in Acrobat Reader
8. YES: Have the link visible also in the printed version
9. YES: No strange additional icon
10. NO: Link should be marked as link

3. attachfile

\documentclass {article}
\usepackage{mwe}
\usepackage{filecontents}
\usepackage{attachfile}

\begin{filecontents}{paper.bib}
@article{demo,
  author={Demo Author}
}
\end{filecontents}

\begin{document}

% We need "doubleprint", because the text of \textattachfile is not printed when printing a PDF
% We use the idea from https://tex.stackexchange.com/a/19045/9075, accepting that
% the pointers to the files are renderedin semi-bold way
\newlength{\Urlname}
\newcommand{\doubleprint}[1]{\setlength{\Urlname}{\widthof{#1}}\hspace{-\Urlname}#1}

\textattachfile[%
  print=true,%
  color=0 0 0,%
  icon=Paperclip,%
  description={BibTeX entry of this paper},%
  mimetype=application/x-bibtex%
]{paper.bib}{BibTeX}%
\doubleprint{BibTeX}

\end{document}

1. YES: Embed paper.bib into PDF
2. YES: paper.bib should be opened with the OS tool associated with mimetype application/x-bibtex
3. YES: Have paper.bib listed in the attachment section in Acrobat Reader
4. YES: The attachment section should have a proper description
5. NO: Have paper.bib listed in the "\EmbedFiles" in PDF
6. NO: Have paper.bib listed in the bookmarks section
7. Partially: Have a working link to paper.bib in the PDF. Double Click in Acrobat Reader, single click in SumatraPDF
8. YES: Have the link visible also in the printed version
9. NO: Strange additional icon Acrobat Reader
10. NO: Link should be marked as link

Debug Information

The /Type /Embeddedfile entry is appearing next to the embedding text in the PDF, not in the global file catalog:

The icon is because of the attachment. In Acrobat Pro, one can drag'n'drop the attachment:

4. embedfile together with stackoverflow tweaks

This solution extends the first solution with

• http://tex.stackexchange.com/q/230581
• Opening a non-PDF file clicking on a bookmark

Proposal:

\documentclass {article}
\usepackage{mwe}
\usepackage{filecontents}
\usepackage{embedfile}
\usepackage{hyperref}
\usepackage[atend]{bookmark}

Debugging hints

The tools to list the internal PDF structure are discussed at Best tool for inspecting PDF files?. The screenshots above are made by Acrobat Professional X. iText RUPS seems to be close to Acrobat Professional's capabilities.

Question

How to achieve that eat least following goals are met:

1. paper.bib should be opened with the OS tool associated with mimetype application/x-bibtex
2. Have paper.bib listed in the attachment section in Acrobat Reader
3. The attachment section should have a proper description
4. Have paper.bib listed in the bookmarks section
5. Have a working link to paper.bib in the PDF
6. Have the link visible also in the printed version

Optionally, following would be good:

7. No strange additional icon.
8. Link should be marked as link

Answer 1

This solution does not solve all the problems, but it didn't fit into a comment:

This is similar to attachfile, but without \doubleprint and 9, 10 fixed and making the annotation unmovable:

\documentclass {article}
\usepackage{mwe}
\usepackage{filecontents}
\usepackage{hyperref}

\begin{filecontents}{paper.bib}
@article{demo,
  author={Demo Author}
}
\end{filecontents}

\makeatletter
\newcommand\attachandlink[4]{%
  \leavevmode%
  \immediate\pdfobj stream attr {
    /Subtype /\pdfescapename{#2}
  } file{#1}%
  \immediate\pdfobj{<<
    /Type /Filespec
    /F (\pdfescapestring{#1})
    /EF << /F \the\pdflastobj\space 0 R >>
  >>}%
  \pdfstartlink user {
    /Subtype /FileAttachment
    /FS \the\pdflastobj\space 0 R
    /F 416
    /CA 0
    /Contents (\pdfescapestring{#3 Double click to open.})
  }%
  \pdfstartlink attr{
    \Hy@setpdfborder
    \ifx\@pdfhighlight\@empty%
    \else%
      /H\@pdfhighlight
    \fi%
    \ifx\@urlbordercolor\relax%
    \else%
      /C[\@urlbordercolor]
    \fi%
  } user {
    /Subtype /Link
  }%
  #4%
  \pdfendlink%
  \pdfendlink%
}
\makeatother

\begin{document}

\attachandlink{paper.bib}{application/x-bibtex}{BibTeX entry for this paper}{BibTeX}

\end{document}

1. YES: Embed paper.bib into PDF
2. YES: paper.bib should be opened with the OS tool associated with mimetype application/x-bibtex
3. YES: Have paper.bib listed in the attachment section in Acrobat Reader
4. YES: The attachment section should have a proper description
5. NO: Have paper.bib listed in the "/EmbeddedFiles" in PDF 
6. NO: Have paper.bib listed in the bookmarks section
7. YES: Have a working link to paper.bib in the PDF, double click is required on Adobe Reader
8. YES: Have the link visible also in the printed version
9. YES/NO: Strange additional icon in Adobe Reader only on Mouseover
10. YES: Link should be marked as link

The Goal 5, listed in /EmbeddedFiles, would be easy to add and probably would add paper.bib to the bookmarks section in SumatraPDF as well (I'm not sure about this one, I couldn't get SumatraPDF to show a bookmarks section for any PDF), but there would be side effects: To open the embedded file without Javascript in Adobe Reader, it has to be added as a File Attachment Annotation at a special location, while files referenced in the /EmbeddedFiles directory are attached to the whole document. One file can be referenced in both ways, but then Acrobat Reader for example will list the file twice.
