This is a summary of my discussion with Maryana on mobile instrumentation needs:
Registration tagging The ServerSideAccountCreation log only knows about mobile vs desktop registrations. Down the line we should modify it to tag new accounts by source {desktop, mobile web, mobile app, other}. For now, we can just use the existing log and extract the source by combining the userAgent and displayMobile fields. There are comments on the Schema:MobileWikiAppCreateAccount talk page that require feedback from the mobile team, if we intend to use this log for signups on apps.
Revision tagging We propose the creation of a new “app” tag in MediaWiki on top of the current “mobile edit” tag, which we will keep for backward-compatibility. This will give us an easy way of counting all mobile edits combined or app-only edits. Detailed breakdown of edit volume/quality by app platform or version will be done via EventLogging instrumentation.
App instrumentation Platform-specific logs such as Schema:MobileWikiAppEdit are an ok interim solution but we should revamp the original plans for a consolidated edit funnel instrumentation to be able to compare edit funnel events across different platforms and interfaces. Given that this data is not product/feature specific, it’s likely an Analytics responsibility to implement it.
Tablet edits We still don’t have a consistent way of identifying and counting edits made on tablets (on our desktop or mobile site), but we can get some initial estimates by using UA data from the last 30 days.
Mobile dashboards We will review the existing mobile dashboards to figure out which ones should be eventually migrated to Vital Signs.
