2. APPLICATION PROGRAMMING INTERFACE (API)
API" stands for Application Programming Interface
API is a standard that allows programs and software to speak with each other
Helps to access a Web-based software application or Web tool
Companies releases their API in public domain so that other developers can design products that are powered by its service
A good, easy-to-use API attracts developers to create programs on your platform

3. PROFILE OF MODERN LEARNER

4. TIN CAN – ADVANCED DISTRIBUTED LEARNING (ADL)
Tin Can API developed by ADL for mobile content learning platform
Project name was Tin Can and now called Experience API or xAPI
xAPI is considered to be next gen SCORM
Helps to track and define how formal and informal eLearning sessions are tracked and measured by Learning Record Stores, or LMSs
Training organizations need to track the amount of informal learning consumed to understand the needs of the learner

5. XAPI AND TRACKING
xAPI was built to expand on that and learn even more about a user's learning behavior
How many employees completed the mandatory annual compliance policy?
How many employees are using the wiki to access and track operational procedures?
xAPI helps organization track these instances
People learn from interactions with other people, content, and beyond. These actions can happen anywhere and signal an event where learning could occur
All of these can be recorded with the xAPI

6. XAPI SPECIFICATION
xAPIs refer to a shared language for systems to communicate data about a person or a group's formal and informal learning activities
The specification requires a Learning Record Store (LRS) to receive and distribute these statements
To record an activity, the application sends secure statements in the form of “Noun, verb, object” or “I did this” to the LRS
LRS record all of the statements made. An LRS can share these statements with other LRSs.
An LRS can exist on its own, or inside an LMS
Structure of the xAPI is open, statements and tracks any type of activity in any system
Flexibility in type of data, helps track
learning activities tied to performance
indicating the real business value of learning or
training initiatives

7. XAPI LEARNING RECORD STORE (LRS)
LRS collects activity statements
An LRS must accept any properly formatted data and share it with other LRSs upon proper request and authentication
An LRS is defined as part of the xAPI specification
Most of the hard logic for dealing with the data is put in the LRS instead of in the tools making the activity statements
LRS is more complex to build than a typical database because it has to accept all the data that is received as part of a statement

9. SCORM & XAPI (TIN CAN) – COMPARISON
Feature-wise xAPI scores over SCORM
SCORM useful when learning happened from within office on a desktop
xAPI scores as devices are multi- distributed and learning can happen from anywhere

10. FREEDOMS OF XAPI
Statement freedom: the structure of “statements” using nouns, verbs and objects lets you record almost any activity. Examples: “I did this.”
History freedom: the Tin Can API allows LRSs to talk to each other. LRSs can share data and transcripts with one another, and your experiences can follow you from one LRS (or organization) to another. Learners can even have their own “personal data lockers” with their personal learning information inside them.
Device freedom: any enabled device can send Tin Can API statements (mobile phones, simulations, games, a CPR dummy) with occasional connectivity is fine.
Workflow freedom: tracking learning events doesn’t have to start or end in an LMS, it can start wherever the learner is and on whatever device they choose to use. Your content isn’t tied to an LMS

11. TIN CAN TO XAPI – OVER THE YEARS
xAPI EVOLUTION
2013
(v 1.0.1)
A patch release, version was released in October of 2013
Tin Can API version 1.0, launched in April of ADL’s official name for the Tin Can API is the Experience API, or xAPI.
2012 (Devlearn)
DevLearn ’12 conference, version .95 of the Tin Can API was finalized and by the end of 2012, there were over 40 adopters of Tin Can.
2012
ADL and the spec community completed version .9 of the Tin Can API, and ADL announced it to the e-learning community. 15 companies/products had adopted the Tin Can API.
Rustici Software looked at the LETSI SCORM 2.0 White Papers, and conducted extensive interviews with the e-learning industry. This Project Tin Can was the beginning of steps towards improving e-learning standards.
2010
Advanced Distributed Learning (ADL), the governing body for SCORM, issued a Broad Agency Announcement (BAA) to solidify the next-generation e-learning standard. Rustici Software was awarded the BAA, and work began.
2008
Noticeable limitations in SCORM forces Learning Education Training Systems Interoperability(LETSI) to seek ideas
