pdfx-ext

Updated and extended version of LaTeX package pdfx by River Valley. In accordance with the LPPPL, this new version has a new name to avoid confusion.

It mostly focuses on PDF/A-1b compliance and eventually including a reference list in the XMP metadata.

The original package was distributed under the LaTeX Project Public License; this is too.

Goals

I had a few ideas for this package:

• support all constructs of the original package (including Subject, which wasn't implemented before)
• comply with the PDF/A standard (which has its quircks, like allowing at most one dc:creator in PDF/A-1)
• allow the author's URI to be embedded as dcterms:creator
• embed a subset of the PRISM vocabulary in XMP in the PDF/A prescribed way (partially complete)
• embed (subsets of) the FaBiO and CiTO ontologies in XMP in the PDF/A prescribed way
• use XMP to embed a layout style-independent and machine readable reference list
• provide a construct (macro, or a program) to convert BibTeX to PRISM+CiTO statements in XMP
• be a reference implementation for connecting PDF documents created from LaTeX to the Semantic Web/Web of Data :)
• support PDF/A-2, which supposedly supports multiple dc:creators

Instructions

Basic install instructions:

• put *.xmp, pdfx-ext.sty and glyphtounicode-cmr-tex in a directory pdfx-ext in $TEXMF/tex/latex

Usage instructions:
