In order to track pageviews originating from Explore Feed cards we will need to add the values listed below to tracking event data sent to stream event.ios_article_link_interaction. We will be adding more in-depth Explore Feed event tracking (Clicks, time_spent, etc.) in a separate task but in order for us to get baseline engagement data quickly this will be a first step for measuring Explore Feed activity. See deck for specifics.

iOS Explore Feed Instrumentation - Phase 1 ios_article_link_interaction

Note: The Explore Feed Card 'Picture of the day' does not go to an article, it just shows the Commons image file, so this may not be trackable using the same data structure we use to track article views in event.ios_article_link_interaction, if this can't be included we will have to omit until we get to the bigger Explore Feed tracking event project.
