Structural items

A rowing regatta generally hosts one or many events of different competition classes. Distinction is made by at least the following criteria:

• rowing discipline (needs to be settled):
  • rowing (Q159354) (no specific class item)
  • para rowing (Q1575010) (PR1 (Q4654434); PR2 (Q7669456); PR3 (Q47507894) with subclasses PR3-B1 (Q6460135), PR3-B2 (Q17129943), PR3-B3 (Q6460140) and PR3-PD (Q6460141); ID (Q17126184)); there is also an item para rowing classification (Q4680764)
  • maybe also ocean rowing (Q7076154), coastal rowing (Q5138340), …
• gender
• age
• athlete mass
• boat class (see below)

Some aspects of rowing events are typically not considered to be part of the competition class:

• racing distance (Q126017): varies from ~250 m to more than 100 km; event distance is a property of an event
• certain communities (debatable, not yet set up): restrictions to college rowers, novices, club teams, etc.

Scope

We can now define competition classes for rowing events, and here we focus on those that are held (or have been held) at the following rowing competitions:

• rowing at the Summer Olympics (Q720609) (and other important multi-sport event (Q167170))
• World Rowing Championships (Q1413606)
• European Rowing Championships (Q80767) (and other continental regattas)
• World Rowing U23 Championships (Q2953911)
• World Rowing Junior Championships (Q6139189)
• World Rowing Cup (Q1974959)

How to tag

Competition class items in rowing are defined as follows (the item men's eight (Q26214799) may serve as an example):

• instance of (P31): competition class (Q22936940)
• short name (P1813): descriptor of the boat class, e.g. M8+ for the men's eight (Q26214799). Use English as language.
• sport (P641): rowing (Q159354) or subclass thereof (e.g. para rowing (Q1575010), coastal rowing (Q5138340), or ocean rowing (Q7076154))
• competition class (P2094): applicable items as follows; all defining parameters for the competition class should be used as individual value, and their type should be indicated by a criterion used (P1013) qualifier
  • statement values for qualifier criterion used (P1013) age of a person (Q185836):
    • open (Q2735683) (Senior A)
    • under-23 sport (Q14510042) (Senior B)
    • under-19 sport (Q21193184) (Junior A)
    • under-17 sport (Q21193196) (Junior B)
    • under-15 sport (Q21193209) (Junior C/kids)
    • senior sport (Q1395783) (Masters, starts at an age of 27 in rowing)
  • statement values for qualifier criterion used (P1013) gender (Q48277):
    • female (Q6581072)
    • male (Q6581097)
    • mixed (Q1940854)
  • statement values for qualifier criterion used (P1013) mass (Q11423):
    • lightweight class (Q26211786)
    • open weight class (Q26211781)
  • statement values for qualifier criterion used (P1013) boat class in rowing (Q26211803):
    • one of the specific boat class items in Wikidata:WikiProject Rowing/boat classes
  • statement values for qualifier criterion used (P1013) para rowing classification (Q4680764):
    • PR1 (Q4654434)
    • PR2 (Q7669456)
    • PR3 (Q47507894) (but not PR3-B1 (Q6460135), PR3-B2 (Q17129943), PR3-B3 (Q6460140), or PR3-PD (Q6460141))
    • ID (Q17126184)

How to use

Competition class items can then be used to define the competition class of rowing events with the competition class (P2094) property. An example would be:

⟨ rowing at the 2016 Summer Olympics – men's eight (Q22968987)    ⟩ competition class (P2094) ⟨ men's eight (Q26214799)    ⟩

Rowing event items with a missing competition class (P2094) claim can be found with this query.

Due to the hierarchical competition class (P2094) structure it is possible to query events according to specific criteria. For instance “all lightweight rowing events” regardless of gender, age, and boat class can be queried like this:

SELECT ?item WHERE { ?item wdt:P31 wd:Q21246076; wdt:P2094* wd:Q26211786 }
