PDF Metadata

Should we use metadata in PDF files?

At first glance, it looks like well-structured metadata (e.g., XML) may be the way to add bibliographic citation information to PDF files.

There is a program that appears to support PDF metadata: Advanced PDF Tools.

Here is their website: http://www.verypdf.com/pdfinfoeditor/pdf-metadata.html

There are two relevant versions of the software, one that has a WYSIWYG interface and the other as a command-line entry. The website descriptions indicate that this software might do what we need. However, in the short time I tried the program I could not find out how to get the metadata out of the PDF file.

Clearly, more time needs to be spent on this software.
