From Wikitech
This page is currently a draft.
More information and discussion about changes to this draft on the talk page.

This page provides links to data documentation for private and public Wikimedia data sources. Its primary audience is WMF data analysts, product teams, and researchers who have an official non-disclosure agreement with the Wikimedia Foundation.

  • Private data requires production data access. It includes datasets in WMF's Data Lake: a large, analytics-oriented repository of data about Wikimedia projects.
  • A selection of public data sources are linked here, but public Wikimedia data is described more fully at meta:Research:Data.

Traffic data

Analytics data about wiki pageviews and site usage.

Private traffic data

Most Data Lake traffic datasets are updated at hourly granularity, with 2-3 hours lag behind real-time. This data includes:

Instrumentation data

EventLogging enables Wikimedia data analysts and researchers to track data that MediaWiki doesn't normally log. Through the Event Platform and Metrics Platform you can create your own instruments using event data like:

  1. Logs of changes to user preferences
  2. A/B testing data
  3. Clicktracking data

These datasets are stored in the event and event_sanitized Hive databases, subject to HDFS access control. To learn how to access these data sources to create your own instruments, visit Collect data.

How to query private data
