When you combine the IMS Learning Tools Interoperability (LTI), Deep Linking (Content Item), 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 and MOOC platforms using IMS standards. Tsugi tools also can integrate into Google Classroom. 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. A number of open source Tsugi Tools are hosted and free to use at www.tsugicloud.org. This presentation will highlight how IMS standards can be used to deploy an educational app store and talk about how an App Store lays a foundation towards a Next Generation Digital Learning Ecosystem (NGDLE).
