'has primary data subject'

[dexink]

Discussed during OMRSE monthly meeting, 5 March 2025:
The property 'has primary data subject' was proposed as a possible axiom of 'SubClass of' for the new child classes of 'social category data item' (also a new class; see closed issue #251). While this was determined as unfitting, the property itself drew attention. The scope listed for the property was noted as being somewhat too limited for prospective use cases. Further, it was suggested that —while the definition was discernibly apt— the label was also in need of revision.
