    "Entity"entities corresponding to the item
  • Any type from $ExternalIdentifierTypes can be used as a property to request an ExternalIdentifier object of the specified type.
  • WikidataData[item,"Properties"] gives a list of all available properties for the specified item. Named subsets of available properties can be obtained with WikidataData[item,"sname"]. Possible values for "sname" include:
  • "IdentifierProperties"external identifier properties
    "NonIdentifierProperties"all properties excluding external identifier properties
  • An item can also be specified as Entity[].
  • An implicit list of items can be specified as EntityClass[type,{prop1vspec1,}], where type is an entity type or an ExternalIdentifier object, the propi are EntityProperty or ExternalIdentifier objects, and the vspeci are values or Boolean operators.

  • EqualTo[x]the value is equal to x
    UnequalTo[x]the value is unequal to x
