I think the jekyll course experiment looks interesting and I can see how it can really work for a team working together, one of whom has experience working with mark up and git.
It looks like a good direction and looks fun to work with as well.
There is also a danger that you could leave a lot of casual course producers or contributors behind.
@dirk - In terms of evaluating Booktype would actually ignore the focus on book production. If you look at the tech rather than the framing I think it’s clearer. So think course and activities instead of book and chapters.
The key bits I think that Booktype has in common with Lernata are:
a) blog style wysiwig and easy image / file upload
b) easy ordering of chapters / activities
c) ability to clone courses
And then there’s some good extra bits too:
a) importing of single chapters / activities from other courses
b) automatic attribution of collective contributions
c) access control to allow wider editing of courses or a more restricted approach
d) output to various formats for offline use, tablets, print or transport to other systems, epub, odt, pdf
The interactivity part may be missing a bit but with 3 developers working on Booktype I think they would be really interested to look at how Booktype could potentialy be a replacement for Lernata if you are leaving that behind.
