What is the Experience API?
• Interoperable, flexible, granular way to track experiences,
scores, progress, teams, virtual media, real-world
experiences (not just completions)
• Allows data storage AND retrieval (ex. 3rd party reporting
and analytics tools)
• Enables tracking mobile, games, and virtual worlds
experiences – most any activity online or offline
• Developed by open source community
4
Track it – store it – act on it
Human readable statements stored in
a learning record store (LRS - Cloudbased data store typically using a noSQL Db)

Services
• Activity aggregation for meaning
• Recommender engines
• Real-time reporting and stats
5
Activity Streams
• Collaboration between Google, Facebook,
Microsoft and others
• Format: <Actor> <Verb> <Object> (I did this)
•
I (actor) completed (verb) the IA course (activity)
• Allows reporting of experiences, not just
completions

Online learning experience tracking
• Learner centric as “actor”
• Pre-defined vocabularies and statements for formal learning
activities
• Most any online activity can be tracked for informal learning activity
data
• Uses “activity providers” which can exist as plugins for most any
application
–
–
–
–
LMS’s – e.g. Moodle, Bb, others
WordPress
Browsers – e.g. Chrome, Firefox, IE
Ect.
• Can integrate with other API’s – e.g. Facebook, Google, Twitter
potentially allowing expanded activity tracking with xAPI as the
common denominator (interoperability).

Transitioning learning experience tracking
• Learning experiences spanning the real and the
digital
• Uses sensors, beacons, gps, bluetooth, wifi…
• Actor roles may flip
• Captured in the cloud with xAPI

Authentication & Authorization
Two methods currently described in xAPI spec
•
•
HTTP Basic Authentication
•
OAuth 1.0a
The xAPI spec permits additional security requirements
to suit organizational needs
•
•
Such as, use of CAC cards, SSL (HTTPS) access only,
etc
Rights can be granular to limit access to
specific parts of the xAPI
•
•
ex. read-only, write activity state, etc
15
Authenticity
•
“Some Statements will have regulatory or legal
significance, or otherwise require strong and durable
evidence of their authenticity and integrity.” -xAPI
4.4 Signed Statements
•
Key encryption and digital certificates can be
attached to Statements to ensure accuracy and
authenticity
