Pulling into the sprint as part of preparing the Nearby feature for deployment.

I would make the following assumptions about what data to collect—does this look right?

• Count clicks on show nearby button T318678
  • Only record "show" clicks and ignore "hide" clicks.

• Count every time a Kartographer map is opened in full screen mode
  • If possible, we'll instrument just the clicking interaction to open a full-screen map. But this might also include the rare cases when a map is opened in full screen mode because the user navigated to a direct link like this.

• % of times someone who opens a full screen map, also clicks on show nearby
  • This depends on recording the user's unique session token, so we'll keep that for 90 days.

• Number of articles with geopoints, added via QID or SPARQL

I think we've missed an interesting metrics possibility, when looking at the frequent question of "number of articles in the database", vs. "number of articles viewed". What if we send an event for every article *added* as you say, which uses geopoints. These events are easy to record and can be deduplicated by article ID, giving an exact count. It's the important component of "number of articles in the database over time" that we would want to graph anyway, and serves as a good replacement for that total. (Basically, we allow ourselves to be slightly blind to the integral of this metric for now.)

Article ID would be IMHO necessary for these "geopoint added" events, and maybe interesting to include in the other event types as well. Eg. we could learn what types of article are more often viewed with nearby, etc.

Data retention / privacy:

• No identifying information about the user, no edit count bucket, no IP address.
• After 90 days, we'll keep the metrics but will drop session_token. This means we can no longer associate eg. full-screen and nearby events on this archived data, but we can still compare the totals over time.

Random suggestion:

• Count the first mouse interaction with a dynamic thumbnail map, as a complement to the full-screen count.
