Proposal: Slideset

I'd like to propose a new subclass of CreativeWork for slidesets.

As background, I'm currently encoding Slideshare views, as part of the 
EUCLID Project (euclid-project.eu) public monitoring application.

I've seen that one can attach interactionCount to CreativeWork - 
although it's a shame that this is direct, not an event in itself (and I 
don't have the data to track each view), I was thinking of encoding each 
poll of the Slideshare API in its own named graph and using the latest 
such to surface a 'current count' through RDFa.

Comments?
