title: Using @Version in spring-data project
body: <p>I've been working on a RESTful webservice with spring-data. A few days ago a special spring-data jpa REST framework <a href="http://www.springsource.org/node/3553">was released</a>.</p>
  
  <p>Now I noticed the ability to use @Version with this framework. Is this version generated by itself or do you need to do this manually?</p>
  
  <p>And is it possible to use @Version on it's own? (So that I don't have to change anything to my existing repositories/domain etc..) </p>
  
  <p>And do I need to do some extra configuration to make use of @Version?</p>
