Type: Structured¶

A Structured Property may contain a value whose type is injected by its instantiation (e.g. Structured(String)) and may require the presence of a Qualifier and/or Provenance information. In order to instantiate value, the types Qualifier and Provenance can be instantiated as exemplified below:

• Structured(String,Qualifier,Provenance): the type includes a value of type String, which can be qualified by given Scheme and Class, and also contains provenance information relative to the value (which process and/or which data source has provided the value);
• Structured(String,-,Provenance): the type includes a value of type String, without a qualifier, and also contains provenance information relative to the value (which process and/or which data source has provided the value);
• Structured(-, Qualifier, -): the type does not include a value and relative provenance information, but only a given qualifier Scheme and Class; in other words, it defines the usage of a controlled vocabulary.
