I am a Dings, that is private in the Dings-System.
I have a Dings_Number, but it is not Part of the Public-Ontology.
My Dings_Number is primarily intended for internal System use, but it is visible to the Dings_Administrator.
A maximum unspecified Dings_Private is called Unknown_Dings or Dings_Unknown and uses Thing with Dings_Number 60003.md as Target.
A Private_Dings is created by the System while scanning Dings_Markdown-Files or Side-Car-Files, when virtual Meaning is detected.
A Private_Dings can become a Public_Dings only by manual decision of the Dings_Administrator.
During Reification the Dings_Number remains the same, but the Dings becomes persistent and Part of the Public-Ontology.
