From the homepage:
Welcome to edX Code, where developers around the globe are working to create a next-generation online learning platform that will bring quality education to students around the world.
EdX is a not-for-profit enterprise composed of 27 leading global institutions, the xConsortium. Since our founding in May 2012, edX has been committed to an open source vision. We believe in pursuing non-profit, open-source opportunities for expanding online education around the world. We believe it’s important to support these efforts in visible and substantive ways, and that’s why we are opening up our platform and inviting the world to help us make it better.
If you think topic maps are relevant to education, then they should be relevant to online education.
Yes?
A standalone topic map application not needed in this context but I don’t recall any standalong application requirement.
I first saw this at: edX learning platform now all open source.
