Several people asked me for a copy of Leonard’s presentation from MAX 2009. The session has been recorded but not posted yet so for now, you can look at the PDF file.
Here’s the description
PDF: Inside and Out
Learn surprising details about the inside of a PDF file. Learn about Adobe turning PDF over to the International Standards Organization(ISO). Adobe expert Jim King will describe what Adobe’s original intentions were with PDF and how that fundamental architecture has been robust enough to evolve and support the features customers have required over the last 16 years. PDF standards architect Leonard Rosenthol will explain how Adobe no longer “owns” the PDF standard after it became ISO 32000-1. You’ll understand why PDF has survived and become an international standard when some other document formats with similar goals are now extinct.
