discussion of the Creative Commons Metadata work

[Enrico Masala <masala AT polito.it>]

I just want to let you know that I wrote a simple Java program that is 
able to insert (and show) the Creative Commons License info into the XMP 
stream of a PDF file.
This has been mainly developed for the Linux platform, but since it is 
written in Java, it can run on every platform.
You can find all the details, and the code, on my home page at:
