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:

Dear Sonagi Kim,
I tried to embed CC licensing metadata in a PDF file using XMP.
This is what I was able to do.

I used Adobe Acrobat 7 Professional.
I downloaded the XMP file for my license from the cc website:
http://creativecommons.org/license/xmp?q_1=2&q_1=1&field_commercial=n&field_derivatives=n&field_jurisdiction=&field_format=&field_worktitle=&field_description=&field_creator=&field_copyrightholder=&field_year=&field_sourceurl=&lang=en-us&language=en-us&n_questions=3

Unfortunately after many trials I was not able to import it in Acrobat.
However, Acrobat 7 Pro allows you to specify copyright info by hand.

Choose "Document Properties", then "Additiona Metadata" and in the
Description panel you can specify copyright status (copyrighted),
Copyright notice "This work is licensed..." , and URL
"http://creativecommons.org/licenses/by-nc-nd/2.5/";.

I also downloaded the CreativeCommons Panel
http://creativecommons.org/technology/CreativeCommonsPanel.txt
but I had some difficulties to make it work properly.
However it shows the CC info once you insert it in the file as I have
described.

Once you inserted all your metadata information, Acrobat 7 Pro also let
you save the xmp description of what you have inserted.

I suppose the XMP information is visible only using Acrobat 7 (not 6).
If you use Linux, you can also show the (raw) XMP info of a PDF file using
pdfinfo -meta file.pdf

By the way, the file I tagged with the CC licence are public and they
available here:
http://www.multicomm.org/program.html, for instance
http://www.multicomm.org/proc_multicomm06_all.pdf


Hope this helps.

Thanks Mike.
I misunderstand what you mean. I describe what I want to do.
I have translated HTML to PDF. It is working properly if I use only DC
Metadata.
But if I write other tag in XMP and load this file in PDF, I cannot see
right information.

I want to use my own tag such as "co-author" and "related paper".
I define this kinds of tags as namespace and XML Schema.
Then I want to use this tag in PDF. But I don't know how to do after this.

How can I do? How can I use my own tag(element or attribute) in XMP?
Actually I don't have much experience to deal with XMP.
please help.


Best,

Ryan

you mean it is impossible to extend my own tag in PDF. Right?
Wrong. You asked if you could "extend the custom panel of PDF." Adobe
calls custom UI forms for metadata "custom panels". I may have
misunderstood what you're after.

Well. I'm so disappointed. why is good for using the XMP in PDF?
Most Adobe papers describe that XMP can extend..Well. confusing?
You can extend XMP, but good luck finding anything to read or write your
extensions. :(
