Difference between subject has role (P2868)?

I don't understand the difference between this property and subject has role (P2868)? Is one meant to be used on the entity and another as a qualifier? U+1F360 (talk) 13:43, 13 August 2018 (UTC)

• Have a look at the sample above which uses confessor (Q21500210) as value for one of these two qualifiers. It can't work with the other.

• To answer my own question. Yes. In a triplestore (like Wikibase) items are stored in <subject/predicate/object> format, so this property is indeed intended to be used a qualifier and subject has role (P2868) ought to be used on the entity itself. U+1F360 (talk) 18:22, 6 February 2019 (UTC)
  • No. Both are qualifiers for statements. It's just that they refer to different parts of the triple. --- Jura 09:24, 10 February 2019 (UTC)

@Deryck Chan: Only you can answer this properly. --Liuxinyu970226 (talk) 12:51, 29 November 2019 (UTC)

@U+1F360, Jura1, Liuxinyu970226: Easy. subject has role (P2868) describes the main item (so it is usually a qualifier, but occasionally a main statement). object has role (P3831) describes the value of a statement (so it can only be used as a qualifier). For example:

• Louis XI of France (Q8058)significant person (P3342)Jean Bouchard (Q3170866)object has role (P3831)confessor (Q21500210) - Jean Bouchard is the confessor (not Louis).
• Bob Dylan (Q392)participant in (P1344)Mariposa Folk Festival 1973 (Q54370683)subject has role (P2868)musician (Q639669) - Bob Dylan is the musician (the festival is not a musician).
