Properties for special forms of variant names

[thoffma]

Up to now, all variant name forms in the GND have been output using the datatype property #variantNameForThePerson. In contrast to the implementation for "Relationships to persons", the relationship code is currently not evaluated for "Alternative name". This means that, among other things, the information as to whether a variant name form is a pseudonym is not transported. This information available in the data should be output in future.

I therefore propose the following addtions

Datatype Properties

#pseudonymNameOfThePerson (PICA 400 $4pseu)
#realNameOfThePerson (PICA 400 $4nawi)
#earlierNameOfThePerson (PICA 400 $4=nafr)
#fullerFormOfNameOfThePerson (PICA 400 $4=navo)
#laterNameOfThePerson (PICA 400 $4=nasp).
(all subproperties of #variantNameOfThePerson)

Examples

Current:

<https://d-nb.info/gnd/131884786> gndo:variantNameForThePerson "Ganßauge, Sophia";
  gndo:variantNameEntityForThePerson _:node1i3f1dpg6x7465615 .

_:node1i3f1dpg6x7465615 gndo:forename "Sophia";
  gndo:surname "Ganßauge" .

Should be:

<https://d-nb.info/gnd/131884786> gndo:earlierNameOfThePerson "Ganßauge, Sophia";
  gndo:variantNameEntityForThePerson _:node1i3f1dpg6x7465615 .

_:node1i3f1dpg6x7465615 a gndo:EarlierNameOfThePerson ;
  gndo:forename "Sophia";
  gndo:surname "Ganßauge" .

Comments and suggestions are very welcome!
