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, 09-15-2008, your first weekly report would use the start date of Sunday and display 09-14-2008 in the individual worksheet tabs and Summary worksheet column. iTunes U emails your detailed Excel spreadsheet report each Wednesday.
Your iTunes U weekly report includes the following worksheets:
Summary. The Summary sheet lists your site’s disk usage, user actions, and software. For more information on the user actions in the Summary sheet, see “Understanding Summary Data.”
Tracks. The Tracks sheet lists all the iTunes U tracks users downloaded that week through the DownloadTrack, DownloadTracks, and SubscriptionEnclosure actions, including track handles and Globally Unique Identifiers (GUID).
Browse. The Browse sheet lists all the iTunes U pages users viewed that week, including page 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 iTunes U 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 iTunes U tracks users previewed that week, including track 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 iTunes U users that accessed your iTunes U site that week, helping you identify the number of unique users accessing your site. This Users sheet only applies to non-public sites. iTunes U can only collect this user data 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.”
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.
Notes:
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 may 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 the following string as a placeholder to identify the user: visitor@itunesu.com.
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 may 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.
