  # gem install xmp exifr
  require 'xmp'
  require 'exifr'
  require 'open-uri'

  img = EXIFR::JPEG.new('spec/fixtures/multiple-app1.jpg')
  xmp = XMP.parse(img)
  xmp.dc.subject #=> ["something interesting"]

  # explore XMP data
  xmp.namespaces.each do |namespace_name|
    namespace = xmp.send(namespace_name)
    namespace.attributes.each do |attr|
      puts "#{namespace_name}.#{attr}: " + namespace.send(attr).inspect
    end
  end
