The identifier at the end of the URI is not a reliable way to retrieve the entity. While most entities can be retrieved from the base url ```http://id.loc.gov/authorities/```, geographic subcomponents throw an error: http://id.loc.gov/authorities/n78095330-781 -- 404 http://id.loc.gov/authorities/names/n78095330-781 -- resolves Proposed solutions: - deprecate use of plain URI entirely and store only component identifier and dataset URI - prefer use of dataset URI and only use plain URI as a fallback (understanding there may be other cases in which it 404s) - require initialization from full dataset URI Research: - How are LoC URIs and identifiers stored by other entities?
