Notes to self

• Use the "applies to parts" when present in "material used"
• develop history so that past exhibitions can be displayed

• clean this mess (e.g.: better access to subproperties, to values of properties in any language, etc.)
• return property values in arbitrary language
  • useful e.g. for "Institution:blabla": "blabla" must be in English rather than in whatever language the user is using.
• clean "object history"
• displayTitle() should use the correct template
  • {{Title |1= |lang= |en= |es= |et=|... }} 1 and lang correspond to P1476, the other are taken from the label.

TODO

• Create a single entity, once, because the operation is expensive: local entity = mw.wikibase.getEntityObject(q_id). --Ruthven (msg) 07:56, 17 October 2017 (UTC)
