Single value: this property generally contains a single value. (Help)
Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303). List of violations of this constraint: Database reports/Constraint violations/P8625#Single value, SPARQL
Distinct values: this property likely contains a value that is different from all other items. (Help)
Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303). List of violations of this constraint: Database reports/Constraint violations/P8625#Unique value, SPARQL (every item), SPARQL (by value)
Scope is as main value (Q54828448): the property must be used by specified way only (Help)
Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303). List of violations of this constraint: Database reports/Constraint violations/P8625#Scope, SPARQL
Allowed entity types are Wikibase item (Q29934200): the property may only be used on a certain entity type (Help)
Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303). List of violations of this constraint: Database reports/Constraint violations/P8625#Entity types
Value type “bibliography (Q1631107)”: This property should use items as value that contain property “instance of (P31)”. On these, the value for instance of (P31) should be an item that uses subclass of (P279) with value bibliography (Q1631107) (or a subclass thereof). (Help)

Inverse property of “main subject (P921)”:
if [item A] has this property (bibliography (P8625)) linked to [item B],
then [item B] should also have property “main subject (P921)” linked to [item A]. (Help)

This property and list of works (P1455)
[edit]How is this different from list of works (P1455)? --Shinnin (talk) 15:10, 21 September 2020 (UTC)
- From my understanding, this property is more generic because it applies to all topic, not only to human. @Thierry Caro: may give his opinion about that. Pamputt (talk) 15:43, 21 September 2020 (UTC)
- @Shinnin, Pamputt: list of works (P1455) is for people's works. The new property is supposedly the list of works about someone or something. Sometimes Wikipedia articles about persons cover both works by that person an works about that person and then one might use both properties here. Thierry Caro (talk) 15:48, 21 September 2020 (UTC)
