mw.eventLog.id was introduced as part of the Better Use of Data initiative and before the Metrics Platform Clients were introduced. mw.eventLog.id is used to expose the user's Active Browsing Session Token. After the Metrics Platform Clients were introduced and widely adopted (spurred on by xLab / Test Kitchen), the performer.active_browsing_session_token contextual attribute effectively superseded the direct use of mw.eventLog.id. mw.eventLog.id should be deprecated and removed.

There are two uses of mw.eventLog.id that need to be tidied up:

• Extension:EventLogging (1 files)
  • modules/ext.eventLogging.metricsPlatform/MediaWikiMetricsClientIntegration.js (1 matches)

• Extension:Wikistories (2 files)
  • resources/instrumentation/consumptionEvents.js (1 matches)
  • resources/instrumentation/contributionEvents.js (1 matches)
