module Valkyrie
# This is a namespacing module for metadata persisters as per the DataMapper pattern
# https://en.wikipedia.org/wiki/Data_mapper_pattern
#
# @note These persisters do not store binary content.
# See Valkyrie::Storage for persisting binary content (files).
#
# @example Register persisters in an initializer using Valkyrie::MetadataAdapter.register
# Valkyrie::MetadataAdapter.register(
# Valkyrie::Persistence::Memory::MetadataAdapter.new,
# :memory
# )
#
# @example Retrieve a registered persister using Valkyrie::MetadataAdapter.find
# Valkyrie::MetadataAdapter.find(:memory)
# => <Valkyrie::Persistence::Memory::MetadataAdapter:0x007fa6ec031bd8>
#
# @example Saving an object
#
# object1 = MyModel.new title: 'My Cool Object', authors: ['Jones, Alice', 'Smith, Bob']
# object1 = Valkyrie.config.metadata_adapter.persister.save(model: object1)
#
# @see https://github.com/samvera-labs/valkyrie/wiki/Persistence
