10 years ISO 32000

In July 2008 ISO has published their first PDF standard as ISO 32000-1:2008. The specification can also be downloaded for free from Adobe. The standard is based on the PDF specification 1.7 from Adobe published in November 2006.

Adobe had transferred the PDF specification to the ISO in 2007. One of reasons was the fight between Adobe and Microsoft about the future standards for electronic documents. Microsoft had proposed their XML based document formats used in Microsoft Office for ISO standards.
