Hello,

suppose you have a long list of pdf files and you want to add the same
metadata
(say, Author, subject) to all of them. Is there an utility somewhere
that does it?

Thanks,
Bob

iText (Java) or iTextSharp (.NET) can do this.
You can add regular PDF metadata, XMP metadata or both.

This is some sample code that adds an author and a title,
in the form of both regular and XMP metadata:

PdfReader reader = new PdfReader("HelloWorldNoMetadata.pdf");
PdfStamper stamper = new PdfStamper(reader,
  new FileOutputStream("HelloWorldStampedMetadata.pdf"));
HashMap info = reader.getInfo();
info.put("Author", "Bruno Lowagie");
info.put("Title", "Hello World stamped");
stamper.setMoreInfo(info);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
XmpWriter xmp = new XmpWriter(baos, info);
xmp.close();
stamper.setXmpMetadata(baos.toByteArray());
stamper.close();

br,
Bruno

and a 'for' loop in your shell. (recommended!)
