answer: women's javelin throw
answer type: Tournament event.
auxiliary information: The Women's Javelin Throw at the 2009 World Championships in Athletics will be held at the Olympic Stadium on August 16 and August 18. The event featured four athletes whose ability was so much better than the opposition that Mirko Jalava of the IAAF said it would be a "major surprise" should another athlete beat them to the podium. The Olympic champion and world record holder Barbora ≈†pot√°kov√°, and Beijing silver medallist Mariya Abakumova, had not matched their Olympic form of the previous year but remained strong contenders for the competition. The other two athletes came from the German team, which was headed by world-leader and two-time World medallist Christina Obergf√∂ll, as well as the veteran Steffi Nerius who won silver in 2003, 2005 and 2007. Osleidys Men√©ndez, Sunette Viljoen and Madara Palameika were the outside contenders. A modest qualifying round was highlighted by Abakumova's world-leading throw of 68.92 m, while German number three Linda Stahl and Slovenian Martina Ratej threw season's bests to qualify as the second and third best throwers. The first round saw the elimination of two of the season's top-six athletes, Palameika and Viljoen.

answer type: File Format.
auxiliary information: Portable Document Format is a file format used to present documents in a manner independent of application software, hardware and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics and other information needed to display it. In 1991, Adobe Systems' co-founder John Warnock outlined a system called "Camelot" that evolved into PDF. While Adobe Systems made the PDF specification available free of charge in 1993, PDF was a proprietary format, controlled by Adobe, until it was officially released as an open standard on July 1, 2008, and published by the International Organization for Standardization as ISO 32000-1:2008, at which time control of the specification passed to an ISO Committee of volunteer industry experts. In 2008, Adobe published a Public Patent License to ISO 32000-1 granting royalty-free rights for all patents owned by Adobe that are necessary to make, use, sell, and distribute PDF compliant implementations.
