Terms and definitions for data used within the Digital Collections Search Reports.

All of these reports are for determining human usage. As a result all requests made by bots, or that have failed, have been excluded from these stats

Terms used in reports

FCO Views by Session: A view is counted if the user visits the FCO page. It is only counted once, no matter how many times they view it within their session. FCO sub/alternate/extra pages do not count (e.g. staff, debug, etc).
This data is sourced from the search logs
Media Interactions: How many times a media asset (image, video, file, etc) has been requested from our asset server. Basically, how often an object has been seen by someone's browser. This is Views + Downloads + Zoom Views + IIIF Views
This is counted as many times as successful requests are made. We don't have any session data for assets.
This data is sourced from the asset logs
FCO Counts: A breakdown of the number of FCOs that are assigned a particular format. These are the same formats that users will see in their facets. Note that a single FCO can have one or more formats assigned to it, so the "total" might not be the sum of all format types.
Child Object Counts: A breakdown of the number of child objects based on their general mime type. A child object can only have one format type, and these values don't really correspond to any user interface element. The total is a sum of all child objects, since only one type can exist for a child.
Views: How many times a request has been made to an asset. This includes all static derivative versions of an asset (large, thumbnail, low-quality, etc)
Downloads: How many times the user has clicked on the "download" button in the search interface (this adds a special parameter onto the URL to force a download)
Zoom Views: How many times a request has been made to the Zoom index (the start of a pan & zoom view)
IIIF Views: How many times a request has been made to the IIIF endpoint
Zoom Tiles: Zoomable images are implemented by breaking the large image up into smaller tiles. As a user zooms and pans tiles will be served up. This is the count of how many of those tiles have been served up

General definitions

FCO: First Class Object - The bibliographic representation / record of the object. The page that you view in the search interface (which may have multiple child elements)
Session: A browser session - this is created when the user first visits the site, and is reset when they quit their browser or clear their cookies
Collection: A number of items grouped together. This is the grouping unit for display in the user interface. An FCO can belong to none, one, or more Collections
Project: A number of items grouped together. This is a grouping unit that is *only* for internal use. An FCO can only belong to one project.

Notes about data

Because collections can have multiple memberships, or none at all, you can't sum results between collections.

Data is generated from multiple sources. The stats log is one component, and has a data dictionary available at Statistic Logs.
