A building block is available to provide integration with Blackboard and can be found here https://github.com/OSCELOT/bb-basiclti. The block includes LTI integration which allows users to single-sign-on from Blackboard and to launch workspaces from Blackboard.
Grades from ATLAS can also be distributed back to the gradebook function in Blackboard.
Blackboard tutors with suitable permissions in ATLAS can create workspaces based on membership of their Blackboard course using an inbuilt wizard.
