Schema classes represent a structured view of the inherently unstructured container data source passed into the constructor. They're used to represent what fields a given object is expected to have. Note that a schema can be applied to a container which doesn't contain all of the named fields; in that case, some of the field accessors will return null, and the caller should use default values for those fields.
