xAPI Live - What is xAPI?

The Experience API, or xAPI, is a
common way of sharing information
about our experiences, using data.

The “x” in xAPI is for experience.

Data describing our experiences
can come from diﬀerent sources.

The Experience API (xAPI)
• Can be used to to describe a wide variety of experiences
• Moves us beyond simple web-based, didactic models
• Promotes adaptive design and development practices
• Accelerates integrations with other systems (and practices)
• Encourages transparency in data capture and use

How do you use xAPI?
• How can I inform better business decisions?
• How do I avoid locking us into a solution?
• How can I make investments in learning development last longer and
more future-proof?
• How can I make sure what I evaluate today is useful in the future?
• How will I connect a learner’s activities across multiple applications?

How Does Experience API Work?
• People interact with “stuﬀ”  
(i.e. content, apps, business systems, etc.)
• These interactions are observed and described in JSON.
• The “stuﬀ” sends the statements to a Learning Record Store.

What is a Learning Record Store, or LRS?
• It’s a database that stores activity statements - the “data”
• LRSs can be software (even hardware) that stands on its own.
• LRSs can be a function of other things: 
data appliances, enterprise applications, LMSs

LMS vs. LRS
A Learning Record Store (LRS) addresses one capability of a typical  
Learning Management System (LMS).
User Management Learning Records Scheduling
Course Management Statistics Grade Book
Tracking eLearning Content Storage Search
Assignments Sequencing Delivery
Preferences Reports Assessment

Activity Statements are “Observations”

xAPI is an open source speciﬁcation. It’s
*licensed so that anyone can use it and create
things based on it without needing permission or
paying anyone.
*licensed as Apache 2.0, if you’re curious

is the part of the US Department of Defense that continues to
sponsor the collective open source work on xAPI since April 2010.

is the nonproﬁt organization bringing vendors & stakeholders around
the world, across industries to maintain xAPI and steer its evolution.

What are other terms we might
hear?

An experience can be thought
about as a set of activities.

A profile is a set of rules that govern
how to use xAPI in specific ways for
specific experiences.

A proﬁle can have one or more recipes in it. A
recipe ensures consistent data for a given activity
so that diﬀerent tools can provide (and make sense
of) data on the same learning experience.

Interoperability is the expectation that what works
in one system will work for a set of other systems
by default with no conﬁguration necessary.

For xAPI, interoperability means that data
created in one system can be shared with
appropriate security and used by other systems

A learning activity provider is anything
which generates activity statements
and then send such to an LRS.

Adaptive Learning assesses someone’s current
knowledge state and recommends a sequence of
activity that moves that knowledge state toward a
deﬁned learning outcome.

CMI5 is a proﬁle of xAPI that deﬁnes
“plug-and-play” interoperability between
learning content activities and LMSs.
