I just pushed spira 0.0.9, gem install and enjoy.  This one has the
supported way to do this, Spira::Resource.project.  This method is
exactly like Spira::Resource.for, except that no processing will be
done on the given identifier--you could now replace .for if you wanted
to, or use another method entirely.  .for uses it internally.  So your
simple concatenation for base_uri would be something like this
(untested):

class X
  def self.my_for(identifier, attributes = {}, &block)
    subject = RDF::URI(self.base_uri.to_s + identifier.to_s)
    self.project(subject, attributes, &block)
  end
end

No input validation is done on this identifier, so it gives you enough
power to hurt yourself.

Let me know if you have any trouble.

Ben
