Jim King is one of our most respected senior scientists at Adobe. I worked with him on a metadata presentation (pdf) back in late 2004 on metadata for Seybold. It was one of my first major demos in front of a couple hundred people, went off without a hitch!
I recently came across Jim’s website where he posts his presentations. I found this by surfing the Adobe’s del.icio.us site. Great stuff if you want a technical insight into PDF, Color Management (pdf) basics or the Adobe Imaging Mode (pdf).
