GBLxAPI is a new way to collect learning data from across independent applications in an organized way while providing flexibility in data collection.  It is based on the new xAPI (Experience API) specification being adopted by e-learning and other industries.  GBLxAPI provides a vocuabulary of uniform resource identifiers that can be used developers so data can be used and compared easily.

Experience API (xAPI) is an e-learning specfication that lets applications share data about human performance.  It was developed by the Advanced Distribution Learning Initiative of the Department of Defense in the U.S.A as an upgrade from the SCORM specification.  The GBLxAPI standard for K-12 application uses xAPI.  

The GBLxAPI initiative was started by Dig-iT! Games to address learning data interoperabiity in educational games.  The project research received addtional support from the National Science Foundation under an SBIR grant.  Dig-iT! games is currently managing this open-source community initiative by providing admistrative and development support.

The standard is being used in games developed with the Unity engine to collect learning and non-learning event data.  There is a Unity API available to the community for use to accelerate and simplify implementation with the 

The GBLxAPI learning analytics standard supports Javascript game engines and most educational applications.  By design the xAPI standard is multi-platform.  The research project developed an initial JavaScript API to assist developers implmenting the new standard.  This requires updates and will be published on Github when ready.  Those interested in contributing to the development of the API should contact us.

xAPI statements are machine readable JSON.  They conform to the xAPI specification for required structure.
