Hi Sudha

I'm not aware of anything in the project at the moment that deals with offline usage - but you can easily do this yourself using something like node-webkit or Adobe AIR. The former requires no installation by the user and so would be excellent for CD-ROM based content. The latter does require installation but is significantly more feature-rich.

Unless you're talking about offline SCORM access (i.e. with tracking) - in which case that's something that really needs to be handled by the LMS, not by the content. I know Cornerstone on Demand has such an app (still in late beta though?), as does Rubicon's Intuition (which I have used as is very good).

Hope this helps
