"'YOG-DNA' represents the attitudes and freedom of young people and has no restrictions like a traditional 'brand'," said the International Olympic Committee (IOC).
"The 200-day countdown is a great milestone in our journey to the Youth Olympic Games," IOC President Jacques Rogge said yesterday.
"So much has been achieved over a short space of time and we are now in the final stretch. We are not only building an event for the world's most talented young athletes, we are creating a platform to communicate to young people worldwide to interact through sport, culture and education, all of which is underpinned by YOG-DNA, the Spirit of the Youth Olympic Games."
Only one equestrian discipline - jumping - will feature at the Games, from August 14-26, and horses will be provided by the organising committee.
For the team event, there will be six teams representing each continent - Africa, Asia, Australasia, Europe, North America and South America. Penalties are given to teams in cases such as riders knocking down fences or when horses refuse to jump. The team with the lowest demerit points wins.
Riders qualify for the Games based on individual final classification from their National Federations. They must have been born between January 1, 1992 and December 31, 1993 to be eligible for the Games.
The Singapore Organising Committee (SYOGOC) also celebrated the start of the 200-day countdown yesterday by announcing the route of the "Journey of the Youth Olympic Flame" (JYOF), an initiative that intends to bring the Spirit of the Youth Olympic Games to each continent. The Flame will be lit in Athens in July and its journey will visit five international locations, including Berlin (Germany), Dakar (Senegal), Mexico City (Mexico), Auckland (New Zealand) and Seoul (Republic of Korea), before arriving in Singapore in August.
