基本范例  (1)

注册一个含有关于书籍的数据的实体存储：

Wolfram Language code: EntityRegister[EntityStore["book" -> <| "Entities" -> <| "faust1" -> <|"Label" -> "Faust. Eine Tragödie.", "author" -> Entity["Person", "Goethe::89m93"]|>, "faust2" -> <|"Label" -> "Faust. Der Tragödie zweiter Teil", "author" -> Entity["Person", "Goethe::89m93"]|>, "romeoAndJuliet" -> <|"Label" -> "Romeo and Juliet", "author" -> Entity["Person", "WilliamShakespeare::s9r82"]|> |> |>]]

查找 Goethe 写的书：

Wolfram Language code: EntityList[EntityClass["book", "author" -> EqualTo[Entity["Person", "Goethe::89m93"]]]]

取消含有 "book" 实体类型的数据的实体存储的注册：

Wolfram Language code: EntityUnregister["book"]

现在 "book" 实体类型已不再可用：

Wolfram Language code: Entity["book", "romeoAndJuliet"]["author"]

范围  (2)

注册一个实体店，然后再通过实体类型名称将其注销：

Wolfram Language code: store = EntityStore["color" -> <|"Entities" -> {"red", "green", "blue"}|>];
Wolfram Language code: EntityRegister[store]
Wolfram Language code: EntityUnregister["color"]

注册一个实体店，然后通过引用原始的 EntityStore 表达式将其注销：

Wolfram Language code: store = EntityStore["color" -> <|"Entities" -> {"red", "green", "blue"}|>];
Wolfram Language code: EntityRegister[store]
Wolfram Language code: EntityUnregister[store]

可能存在的问题  (1)

创建并注册新的实体存储：

Wolfram Language code: store = EntityStore["t" -> <|"Entities" -> <| "e1" -> <|"p" -> "hello"|> |>|>];
Wolfram Language code: EntityRegister[store];

通过添加一个新实体来修改注册的实体存储：

Wolfram Language code: Entity["t", "e2"]["p"] = "bye";

取消修改后的存储的注册：

Wolfram Language code: EntityUnregister[store];

含有类型 "t" 的存储还处于注册状态，因为它与原来的存储不匹配：

Wolfram Language code: EntityStores[]

通过引用类型 "t" 来取消存储的注册：

Wolfram Language code: EntityUnregister["t"]
Wolfram Language code: EntityStores[]
