Motivation

Opta Sports (Q3354444) is a very prominent sports data company, and they use a consistent ID scheme across all their association football data (which they claim includes 1,000+ leagues/competitions and 200,000+ matches). They do not offer the data for free on their own website (and annoyingly, even their documentation requires a paying account), but their data is used by many other websites, so the IDs can still be found all over the web.

Because most sites cover very few competitions, they tend to create pretty URLs for each of those competitions, so these IDs tend to not be useful for getting broad information about the competition itself. They are more useful when combined with my other proposed properties, Wikidata:Property proposal/Opta football team ID and Wikidata:Property proposal/Opta football player ID, as they are often used in URLs for team/player stats pages (see either of those proposals for examples of La Liga's 23 being used in multiple URLs) –IagoQnsi (talk) 02:15, 22 July 2020 (UTC)
