Data recorded
Tin Can API records data in so called statements. They conceptually capture a learning activity.
These statements are composed by the following elements: subject, verb, activity, result and context. The following table summarizes what PT Anywhere records and how. For a more detailed documentation, visit this page.
| Subject | Anonymized ID. Reused from a previous session ID if possible. |
|---|---|
| Verb | Initialized, terminated, created, deleted, updated and used. |
| Activity | Widget, Device, Link and Command line. |
| Result |
Specific for an activity instantiation. It has general data and application specific information (discouraged because does not promote interoperability). |
| Context | Session ID and activity categorization. |
