The nice thing about schema-free query (navigationless access) is that no matter from what angle you query the hierarchical structure, it preserves the semantics of the structure and the query. In fact the structure can be accessed from multiple angles (paths) in a single query simultaneously. This also increases the data value dynamically. This blog gives a little background and example of this. http://www.adatinc.com/blog1/?p=37
