PDF METADATA AND ITS CONVERSION TO XJDF

Abstract

In this paper, we show an example of how a product description such as the specifications of the print substrate can be embedded as metadata in a PDF file using a well-documented technology for variable data printing. We demonstrate the corresponding data structures in PDF. Moreover, we are explaining how these structures can be integrated in a PDF file and retrieved afterwards with a JAVA program. In addition, this metadata is converted into XJDF, which can be passed on to a commercially available workflow management system. The basic structure of XJDF is explained as well as its generation with JAVA.
