Your iTunes U weekly report covers a four-week period and contains multiple worksheets, each including information about a different week of site usage. The main worksheet, Summary, contains a week-by-week overview of your site activity.
iTunes U captures weekly report data using a Sunday through Saturday schedule, Pacific Time. Sunday is the start of the report week. iTunes U displays Sunday’s date in the individual worksheet tabs and the Summary worksheet columns. For example, if your site was created on Monday, 2008-09-15, your first weekly report would use the start date of Sunday and display 2008-09-14 in the individual worksheet tabs and Summary worksheet column. iTunes U emails your detailed Excel spreadsheet report each Wednesday to the email address specified in the Edit Site Settings page.
Your weekly report includes the following worksheets:
Summary. The Summary sheet lists your site’s disk usage, user actions, total track downloads, and software. For more information on the user actions in the Summary sheet, see “Understanding Summary Data.”
Tracks. The Tracks sheet lists all the tracks users downloaded that week through the DownloadTrack, DownloadTracks, SubscriptionEnclosure, and DownloadiOS actions, including track paths, counts, handles, and Globally Unique Identifiers (GUID).
Browse. The Browse sheet lists all the pages users viewed that week through the Browse action, including page paths, counts, handles, and GUIDs. You can use this sheet to help you determine which pages within your site are most popular.
Edits. The Edits sheet lists all the pages or groups users edited that week through the EditFiles and EditPage actions, including page or group handles.
Previews. The Previews sheet lists all the tracks users previewed that week through the DownloadPreview and DownloadPreviewiOS actions, including track paths, counts, handles, and GUIDs. Previewing tracks does not result in the track actually being downloaded to the user’s iTunes U library.
Users. The Users sheet lists all the users that accessed your iTunes U site that week.
iTunes U can display user strings if you provided identity information (for example, displayName, emailAddress, username, userIdentifier) in your transfer script or logged in using an Apple ID account. When an administrator logs in to your site using an Apple ID account, iTunes U records the administrator’s actions and Apple ID and displays the Apple ID in the Users sheet so you have a record of all administrators accessing your iTunes U site. For more information and details on the identity token data key and identity key values, see “Generating the Token Data.”
To obtain a count of unique users, use the GetDailyReportLogs API to request an iTunes U log report in raw text file format and then perform a uniqueness count on the IP addresses in the log report. For more information on the GetDailyReportLogs API, see “Requesting Daily iTunes U Log Reports.”
If there is no activity in your site, and therefore no data to record, iTunes U displays a value of zero for the period of time with no activity.
If you change a page or track title in your site within a four-week reporting cycle, iTunes U uses the new title when generating your report. If you compare the current four-week report with a previously generated four-week report, values might not add up as you expect because the previous report contains the older page or track title.
If iTunes U cannot log the actual user that performed an action, iTunes U uses one of the following strings as a placeholder to identify the user: email@example.com or n/a.
If an Apple iTunes U representative accesses your site, your report contains an email address of the form: AppleAdministrator@itunesu.com.
If your Summary sheet displays unknown Client Software as “?/?/?,” “?/?/Macintosh,” or “?/?/Windows,” one of the following might have occurred:
The site administrator or instructor uploaded a file or edited a page using a web browser and performed user actions within the web browser.
A user downloaded a track and iTunes passed the download task to another application, usually a web browser. For “?/?/?,” the track download was performed by an application that did not send a user-agent identifying the application on either Mac or Windows.
