One followup.

Why if I dump my list of article objects to YAML, do I end up with
this:

- !ruby/object:Article
  author:
    -
      - "Hovorka, Alice J."
  title:
    -
      - "The (Re) Production of Gendered Positionality in Botswana's
Commercial Urban
        Agriculture Sector"
  url:
http://journals.ohiolink.edu/cgi-bin/sciserv.pl?collection=journals&amp;journal=00045608

I'm referring to the fact that article and title content aren't
represented the same as url (which is what I was expecting).

I have these two classes:

class Article

  include Journals

  attr_reader :title, :author, :description, :url
  def initialize(title, author, url)
    @title = title
    @author = author
    @url = url
  end

  def to_s
    "#@title, #@author"
  end

  def abstract
  #
  end

  def refer
    Journals::const_get(:BASE_URL) + "/" +
    @url + "&form=refer&file=file.txt"
  end

  def pdf
    Journals::const_get(:BASE_URL) + "/" +
    @url + "&form=pdf&file=file.pdf"
  end
end

class Articles
#
  attr_reader :articles

  def initialize
    @articles = Array.new
  end

  def append(article)
    @articles.push(article)
    self
  end

  def [](index)
    @articles[index]
  end
end

.... and then:

list = Articles.new

... and at the end:

File.open("articles.yaml", "w") {|f| YAML.dump(list.articles, f)}

Or is everything fine?
