Description and motivation for this property

Competition classes are used in competitive sports to classify sporting events according to the athletes' physical abilities. Significant classification facets depend on the demands of the sport and are typically a compilation of some of the following parameters:

• Gender of participants
• Age of participants
• Sports discipline within a sport, or variants of the sports equipment; in this context, para-sport events are to be considered as separate disciplines within a sport
• Body weight or height of participants (less often)
• Performance or ability levels (not in professional sports)

The definition of official competition classes is typically carried out by international sports governing bodies. Specific sports competition are usually announced by the organizers with a competition class, and the organizer also checks the eligibility of the entered athletes or teams.

Sports records are also usually recognized separately for official competition classes. If sports equipment is part of a competition class, it can also be assigned a competition class.

Other aspects of the accessibility of sports competitions such as a qualification system, invitation-only competitions or membership of certain peer groups (e.g. school and university competitions, military and police sport competitions, …) are generally not part of the definition of a competition class.

Definition of competition class items

We define competition class items with the following statements:

• instance of (P31): classification in sports (Q1744559) (or a subclass of (P279) that item at any hierarchy level)
• competition class (P2094): value of a classification facet, qualified with criterion used (P1013) qualifiers for the facet itself (one statement per classification facet)
• sport (P641): assignes the competition class to a type of sport whose international sport governing body defines the competition class

For each sport, all relevant competition class items must be created once. Depending on the sport, some few up to more than 100 items will be required (usually a largely complete permutation of all relevant classification facet values).

A list of existing competition class items, sectioned by type of sport, can be found at Wikidata:WikiProject Sports/reports/competition class/competition class items. The list Wikidata:WikiProject Sports/reports/competition class/distinction criterion main values gives an up-to-date overview of used values of classification facets.

Existing competition class items can be verified against EntitySchema:E139.

Use of competition class items

Competition class items are used in items of one of the types sporting event (Q16510064), sports competition (Q13406554), record (Q1241356), sports equipment (Q768186), or sports organization (Q4438121) (usually sports teams) with the property competition class (P2094). No criterion used (P1013) qualifiers should be added in this case, and there should not be more than one competition class (P2094) statement per item. If different competition classes are evaluated in a single event, a separate item should be created for each competition class.

For items about athletes, the indication of a competition class does not make sense. There is no formal rule that relates an athlete to a competition class; basically, an athlete may enter and participate in an event of a particular competition class, provided they meet the restrictions defined by the class. Items about athletes should therefore not use the competition class (P2094) property; instead, all relevant sporting event participations should be listed with the property participant in (P1344), whose value items should contain a competition class (P2094) statement, or alternatively the property sports discipline competed in (P2416) can be used with a sports discipline item as value.

Queries

The property competition class (P2094) is a transitive Wikidata property (Q18647515). This enables us to perform two different types of queries:

• One can search directly for specific competition classes; for example, ?item wdt:P31 wd:Q46190676; wdt:P2094 wd:Q16893403 lists all items of the type tennis event (Q46190676) with the competition class women's singles (Q16893403).
• Alternatively one can search for a particular classification facet; for example, ?item wdt:P31 wd:Q46190676; wdt:P2094* wd:Q6581072 lists all women's events in tennis (singles and doubles events, all age classes). Likewise, different classification facets can of course also be queried in combination.
