This isn't a lot of context to work with, so I'm guessing what might work for 
you.

If you don't want to use poppler / pdfinfo, you could buy the adobe libraries, 
or you could try pdftk. Podofo may also be a possibility.

I do not think this will work in general. It might work for all the PDF files 
you care about though. Read the PDF specification (Section 10.2.2 or 
thereabouts) for information on the metadata stream(s).
