Motywacja

Polish Theater Encyclopedia (Q66972097) has many different data sets, right now we have properties for 'Persons' and 'Theatrical plays' data sets (Encyklopedia Teatru Polskiego person ID (P5058) and Encyklopedia Teatru Polskiego play ID (P6679) respectively). This property proposal refers to the 'Authors' data set.

There are several other data sets like 'Critics', 'Scenographers', 'Encyclopedic entries' (related to theatre) and others. All can be linked in a similar way. Like with Encyclopædia Britannica Online ID (P1417), it'd possible to create one property for all data sets (with values „osoby/1129” instead of „1129” [for 'Persons' data set], „autorzy/2790” instead of „2790” [for 'Authors' data set], „sztuki/208” insetad of „208” [for 'Plays' data set] and so on for other data sets). However, creating this property just for 'Authors', does not rule out merging all properties into one in the future.
