RE: linked open data and PDF

I made a little example PDF based on the example at http://5stardata.info/  where document metadata is in the XMP itself, but document data is just a string value (this example uses JSON).

The same data from http://5stardata.info/gtd-5.html should be available in the attached, starting from http://5stardata.info/gtd-1.pdf.


I thought a concrete example would help
