World Rowing ID (P2091) é uma simples propriedade de controle de autoridade para ligar itens da Wikidata a entradas no World Rowing athlete database (Q21008628). Esta base de dados é operada pelo grupo internacional regulador do rowing (Q159354), o World Rowing (Q684885) (FISA), e contém o grupo disponível publicamente mais completo de dados sobre pessoas e eventos relacionados ao remo.
On 17 December 2020, World Rowing (Q684885) relaunched their website and issued a new Universally Unique Identifier (Q195284) for all rowers; these may be found in the Wikidata property World Rowing UUID (P8990).
On 9 January 2021, World Rowing (Q684885) returned to using the previous numeric identifier (Q93868746) for all rowers, may be found in the Wikidata property World Rowing ID (P2091).
Acrescentar esta propriedade
Para utilizar esta propriedade, precisas determinar o identificador na base de dados da FISA: consideremos o exemplo da campeão olímpico Kim Brennan (Q576663); o seu perfil pode-se encontrar em:
- http://www.worldrowing.com/athletes/athlete/24665/A parte amarela é o identificador para utilizar dentro desta propriedade, enquanto a parte restante do URL está definido dentro da propriedade World Rowing ID (P2091) utilizando a formatter URL (P1630).
- http://web.archive.org/web/20201004003834/http://www.worldrowing.com/athletes/athlete/24665/
- https://www.worldrowing.com/athlete/24665/
The yellow part is the identifier to use within this property, while the remaining part of the URL is defined within the property page World Rowing ID (P2091) using the formatter URL (P1630) property.
A FISA mantém uma base de dados bastante boa que compreende dados de cerca de 50.000 pessoas (outubro de 2016); no entanto, em entre um 1-2% dos casos existem múltiplas entradas para a mesma pessoa (valor estimado). Isto significa que um deveria agregar mais de um valor para esta propriedade num elemento, o que é uma violação da "restrição de valor singular" definida por {{Constraint:Single value}} em Property talk:P2091. Dado que podem-se definir excepções a esta restrição, não é um problema.
In case of multiple values it is also important to set proper ranks for the individual claims. If all important information about a person is contained within a single profile out of the available profiles, then mark the important claim with preferred rank. There are cases, however, in which this is not possible and the information is distributed across multiple important profiles. All of them should use the normal rank. Deprecated rank should not be used at all for any value that has been valid in the past.
Please also add empty profiles which often do not contain much more than a person’s name. We do not know whether FISA will start to add content to database entries which are still (almost) empty.
Use esta propriedade
Within Wikidata this property is used to link against FISA’s database and to identify multiple items per person (via the distinct-values constraint (Q21502410), defined by a property constraint (P2302) statement on Property:P2091). Identifiers can also be queried using the common query tools for applications outside Wikimedia.
On Wikipedias, there are typically templates available (such as Template:World Rowing (Q14334032) and others, see {{ExternalUse}} template on Property talk:P2091) which either store the same identifier locally within the Wikipedia, or take the data from Wikidata by using the {{#property:P2091}} or {{#statements:P2091}} parser function or more sophisticated functions of Module:Wikidata (Q12069631) and others. In case of the existence of a local value, one can also compare it to the Wikidata value and make use of maintenance categories, which are linked from the {{Property documentation}} template on Property talk:P2091. However, be aware that in case of an item with multiple claims, of which none is the primary one marked with preferred rank, you also might get multiple values if you pull this information from Wikidata.
