News to me but it looks like MS is coming out with a tool to help build e-learning modules (learning objects) named Grava.
There’s not much information on the site and I’m a little worried that there’s no mention of any of the standards such as IMS, common cartridge, etc. Hopefully it’s not just another format like most MS offerings though right now there doesn’t seem to be a decent spec anyone wants to support anyways. It’s really an area that could be improved.
There’s some screenshots of the interface.
