The reward for qualification is a place at the men's (24 teams) and women's (16 teams) events that will be hosted at the iconic Luzhniki Olympic Complex in Moscow from June 28 to 30, 2013.
In total 15 places will be available via the men's qualification process and 11 places via women's qualification. In the men's competition 2009 champions Wales, Argentina, New Zealand, Samoa, England, Fiji, Kenya and South Africa are the automatic qualifiers based on their performance at the 2009 Rugby World Cup Sevens.
In the women's competition champions Australia, New Zealand, South Africa and USA are automatic qualifiers. Tournament hosts Russia gain automatic qualification in both the men's and women's competitions.
Direct qualifying gets underway appropriately at the Luzhniki Olympic Complex this weekend when the cream of Europe's women, including Jon Skurr's Ireland side, will compete for the five places available via the European qualification process to join hosts Russia.
International Rugby Board Chairman Bernard Lapasset said: "The beginning of the direct phase of the global qualification process for the 2013 Rugby World Cup Sevens in Moscow is a major milestone for an event that continues to go from strength to strength, representing rugby's continued growth into new markets.
"This qualification system provides a clear pathway for all our Member Unions to secure a place at this prestigious event.
"The process will provide great competition and excitement in itself as teams strive to secure a place at a world class tournament in one of the most vibrant cities in the world, Moscow. It is a key event as we build towards rugby's return to the Olympic Games programme in 2016.
"We are excited about the potential of Sevens. We are already a long way down the road in preparation for the 2016 Olympic Games where our finest men's and women's Sevens athletes will have the opportunity to compete on the world's greatest sporting stage."
The 2009 Rugby World Cup Sevens in Dubai, the first event to feature a Women's competition running alongside the men's, proved to be a watershed event for Sevens, elevating women's rugby to new heights.
Its winning blend of high-octane action, global representation, strong crowds and festival atmosphere played a significant role in the IOC's decision to include Sevens in the Olympic Games programme.
Since then Sevens has reached new heights with widespread multisports Games inclusion, an expanded HSBC Sevens World Series that sets record attendance and broadcast figures year-on-year while the first-ever IRB Women's Sevens Series is set to begin later this year.
Moscow 2013 will be the second Rugby World Cup Sevens to feature a women's event.
The event will deliver its own unique flavour to the Sevens success story with the city looking to embrace rugby fans from near and far with a special festival of activities run at the Luzhniki Olympic Complex over the three days.
