Why Experience API, xAPI● Ready data integration no matter where learning happens
● Record any new experience without limitation, driven by
community
● Gain deeper insights into learning process, accumulate
collective intelligence for different stakeholders
● Data reuse is very efficient (data is the new oil)

Why xAPI is a game changer?
Freedom of data flow
Distributed Learning Ecosystem
Unified data structure and document
APIs (state, activity, learner)
Specialized technologies working
together without pain
Freedom of learning design with best
breed of choices & innovations
![Page 6: Make Learning Big Data Work For You](https://reader031.fdocuments.us/reader031/viewer/2022022202/587b3a0d1a28ab9c0e8b47c7/html5/thumbnails/6.jpg)
Examples of Developments Enabled by xAPI
Social layer (Both Actors and Objects are networked)
Gamification layeror Behavior Engineering Technology
Self-paced & adaptive learning, automated learning flow across x
Integrated data & experiences across platforms / resources
An ecosystem of innovative applications & analytics, and creative uses can grow
out of Data Lakes. (because of data interoperability facilitated by xAPI)

Customized Dashboards
A dashboard is a visual display of
the most important information needed
to achieve one or more objectives
that has been consolidated on a single computer screen
so it can be
monitored at a glance. (provides an overview)

Our Current User BaseThis project is being implemented in Taipei city, Taiwan. All
teachers and students, about 350,000 in number, in Taipei city
will be using this solution (later other areas will join); the public
department is working towards building an ecosystem (from
collaboration of public departments, schools, vendors, scholars,
and developers) based on xAPI standard and open learning data
as Open Data.
