Hi Werner,

probably it makes sense to merge "Video on IPTV" with "Services by using 
an unified media annotation" (6064).

true, I changed that.

agree. Probably we should drop this?

Agree. I added that info to issue 6084.

I agree that this is a very rich use case, but maybe too broad. What do 
others think?

Agree. We could close 6081.

agree.

This seems a good way to build a bridge between media annotation and 
media fragments. But I am not sure if we should classify this as 
something to tackle later, after the first version of the ontology, and 
the first version of media fragments. What do people think?
