Wikidata:WikiProject sum of all paintings/Anonymous creator

This page describes how we handle an anonymous creator as part of the sum of all paintings. This is in line with the visual arts item structure.

If we know who made the painting, we just add creator (P170) set to the right person. If the painting is attributed to someone we still use creator (P170) with the creator, but we qualify it with nature of statement (P5102) set to attribution (Q230768).

The following qualifiers may be used to link the object to a distinguished instance related to its creator:

workshop of (P1774): The object was probably created by students or employees of the artist in the same workshop, possibly with help of the named artist.
circle of (P1776): The object is by an unknown artist who lived in the same time as the named artist in a similar style, possibly a follower or someone who had contact with the named artist.
follower of (P1775): The object is by unknown artists who work in the manner of the named artist.
school of (P1780): The object is by an unknown creator with a style influenced by the known artist or circle, active in the same period, but a student or follower.
possible creator (P1779): There is a bigger uncertainty about the creator of the object.
manner of (P1777): The object is in similar style as the named artist, but not necessary from the same period.
after a work by (P1877): The object was strongly inspired or copied by a work of the named artist.
forgery after (P1778): The object is a forgery trying to appear to be the work of the named artist.

If no distinguished instance is known but some qualities of the value of creator (P170) these should be added. For example:
