API Documentation


Blackboard provides the Building Blocks API and Web Services Specifications for Blackboard Learn 9.1 in an HTML package in Javadoc format.


Blackboard also provides a "diff file" to detail the changes to the Building Blocks API and Web Services Specifications since the previous release of Blackboard Learn. This navigable list of added, removed, and changed public APIs is an HTML package in Javadoc format.


Tag Libraries


The familiar look and feel of the Learn user interface is provided to developers through the Blackboard Tag Library. These are the same tag libraries used in the Learn application and are available for your use.


Java Server Pages constructed using elements from the tag library render the user interface in a manner familiar for users of the Learn application. Using the tag libraries in your Building Block creates a 'seamless' ui experience for your Building Block users.
