module Decidim
  # A ResourceLink allows linking resources (other entities in Decidim) between
  # them without them having to know each other.
  #
  # In order to group the relations between resources you need to specify a name.
  #
  # Some examples could be: proposals that have been created in a meeting or
  # projects that are a result of merging different proposals.
