  11                         A <ref target="Proxy">Proxy</ref> of some <ref target="ore:AggregatedResource">Aggregated Resource</ref> as it exists within a specific <ref target="ore:Aggregation">Aggregation</ref>.

  14                         State·ments about Aggregated Resources which are specific to a particular Aggregation need to be made on a Proxy, as such state·ments are not “generally true”.
  15                         It is recommended that Proxies not be Aggregated Resources themselves, but this isn¦t formally required.
  16                 </p>
  17                 <p>
  18                         There is no restriction that an Aggregated Resource only have one Proxy for a given Aggregation.
  19                         The restrictions on <ptr target="ore:proxyFor"/> and <ptr target="ore:proxyIn"/> are not formally expressed in <ptr target="(OAI-ORE)"/>, but are in <ptr target="(PCDM)"/>.

  21                 <p>
  22                         Horizontal (previous~next) linking for Proxies is described by <ptr target="(PCDM)"/>, with the quirk of using the spelling <resource name="rel:prev"/> for <ptr target="rel:previous" type="property"/>.
  23                         This ontology only recognizes the spelling <resource name="rel:previous"/>, which is formally defined by <ptr target="(RFC5005)"/>.
  24                 </p>
