[BioRuby] [GSoC] ORM styled NeXML

An object invocation of NeXML is very much ORM like. An Otus and a Tree
class could very well be represented as:

class Otus
  include Mapper

  property :id, :label
  has_n :trees

class Trees
  include Mapper

  property :id, :label
  belongs_to :otus

And, one would be able to do following:

otus1.trees << trees1
otus1.trees = [ trees2, trees3]
# => trees1, trees2, trees3
# => otus1

NeXML::Mapper module defines the magic methods property, has_n, and
belongs_to which will use reflection to define the needed methods.

The above representation of Otus and Trees class feels very succinct to me.
It could be due to my Rails/Merb background but, others can see it as a DSL.

What is the take of others on this coding style( including acceptance in
BioRuby ) ?
