Expand the Percentage of articles making use of data from Wikidata dashboard to include (S)itelinks.
This dashboard is updated daily and reports the % of articles in each WMF project that re-use any Wikidata items, subject to the following constraints:
- namespace = 0,
- no redirects,
- (S)itelinks are excluded.
**Motivation:** the current [[ http://wmdeanalytics.wmflabs.org/WD_percentUsageDashboard/ | Percentage of articles making use of data from Wikidata dashboard ]] reports on Wikidata re-use statistics from the [[ https://www.mediawiki.org/wiki/Wikibase/Schema/wbc_entity_usage | wbc_entity_usage schema ]] but excludes the (S)itelinks aspect (see `eu_aspect` field in the respective schema).
Why is the (S)itelinks `eu_aspect` currently excluded? Simply because it represents a somewhat trivial case of Wikidata re-use in the WMF projects (any page is really expected to have a corresponding Wikidata item, so... having a (S)itelink is really a matter of time only). **However**, it was reported that some people were confused with the current Wikidata re-use statistics, expecting to observe higher figures than those reported. The cause of confusion was identified to be exactly the question of whether (S)itelinks count as valid Wikidata re-use statistics or not.
In a discussion with the #research team @MGerlach and @diego, @Lydia_Pintscher and @GoranSMilovanovic came to a conclusion that it makes sense to conceptually separate:
- Wikidata **usage** (i.e. everything excluding (S)itelinks) from
- Wikidata **coverage** (only (S)itelinks).
The existing dashboard will be re-designed to encompass two tabs: Wikidata usage, showing the usage statistics that are currently represented on the dashboard, and Wikidata coverage, introducing (S)itelinks usage only.
