When you combine the IMS LTI, Deep Linking, and Common Cartridge standards and use them together in a coordinated fashion, you can build and Educational App Store that has smooth integration into the major LMS systems using only IMS standards. Tsugi (www.tsugi.org) is a software framework that reduces the effort required to build IMS standards-compliant applications and integrate them into a learning ecosystem. This presentation will highlight how IMS standards can be used to deploy an educational app store like www.tsugicloud.org and talk about how an App Store lays a foundation towards a Next Generation Digital Learning Ecosystem (NGDLE).
