NPGObjConXrefs:Suffix #37

Closed steads closed 7 years ago

Suffix: This field has not been mapped. However, it is a field that qualifies different relationships between the instance of E22 Man-Made Object and the E39 Actors identified in NPGConstituents. The field shows many artefacts of this being part of a display system that has required formatting at the data layer. I would suggest that this is removed during export.

This field is not mapped to anything. But the number of cases is not so great, so it's possible to analyze and map to something.

I analyzed the occurrences of Suffix. There are 67 values, the values with >=2 occurrences are:

 262237 NULL
    338 (Photographer)
     79 (Attribution)
     33 (Forger)
     16 (Sculptor)
     16 (Engraver)
      8 (British)
      7 (Miniaturist)
      6 (Daguerreotypist)
      5 (Former attribution)
      3 (English)
      2 (Russian)
      2 (Printmaker)
      2 (Lithographer)
      2 (Forgers)
      2 (Chinese)
      2 (?)

Then I analyzed the co-occurrence of the most populous Suffix (Photographer) with Prefix:

  Copy after:   (Photographer)
  Derived from: (Photographer)
  Artist:   (Photographer)
  Probably after:   (Photographer)
