[MMSEM-UC] Questions on the tagging use case

Dear George, Thomas and Susanne,

Here are two quick questions on the tagging use case:

1) This is a very exciting use case. Am I right in saying that  the 
interoperability here is among different tagging systems, rather than 
that of existing multimedia standards? Or there are some implicit 
relations between the two?

2) I am not an expert of SKOS and could not quite see how SKOS can help. 
Could you give an example or clarify this point?

Best regards,
Jeff
