Everything is Miscellaneous
Here is a link to Aaron Winborn's blog commenting on the metadata session at the Open Media Camp
http://aaronwinborn.com/blogs/aaron/everything-miscellaneous
One thing we discussed at this session was the possibility of combining taxonomy with folksonomy.
I.e. using both a standard video genre type in conjunction with open or free tagging.
