Reveal.js has a wide range of useful features which include
- nested slides
- nice slide tansition customization
- markdown contents
- PDF export
- speaker notes(useful if author is giving a live presentation)
- a nice API to do things easily
It does have automatic slide transitions at specific interval of time. For linking it with audio position, I'd be using Popcorn.js similar to way its being done in the prototype, but with easy authoring of course.
Markdown could actually be a disadvantage, since WikiEducator authors are familiar with wikitext.
Wiki authors don't need to write/read markdown. They would just be using the UI. Reveal.js would be storing the content in markdown format in sub-pages.
If it is in Markdown format, it won't render correctly on the subpages.
That's why I said that users won't need to read these subpages. Is there a way we can hide the pages? Or do you know a better way to store this data?
I'm thinking of trying to convert the main page only to a slideshow, but I guess parsing wiki text won't be that easy.
My first suggestion would be to store it in wikitext format the way the prototype does. That might allow additional reuse beyond just the slideshow.
