The Access 4 Learning (A4L) Community defines its global Infrastructure to be simple, secure, scalable, and standard. What each of these terms means changes with technological progress.
The A4L Community works hard to balance capabilities with effort required by developers, and as of late this has been accomplished through our Open Source frameworks especially for Service Providers, which open up a lot of flexibility and expected functionality for Service Consumers to enjoy.
