mods.names	name	[OpenStruct.new(:name, :role), ...]
mods.dates	originInfo	["1869"]
mods.forms	physicalDescription	["text"]
mods.abstracts	abstract	["Green leather with gold stamping...", ...]
mods.subjects	subject	["Bookbinding--Techniques--Gold stamping", ...]
mods.access_conditions	accessCondition	[OpenStruct.new(:rights, :reuse), ...]
mods.related_items	relatedItem	[OpenStruct.new(:label, :name), ...]
