On the IPTC web site at https://www.iptc.org/site/Home/Meetings/Machine_Readable_Rights_and_the_News_Industry_day_2013 there is some video that gives the best explanation I've seen of what Getty Connect is, and how it's supposed to work.  Near the bottom of the page at this url there is video of a fellow by the name of Andreas Gebhard presenting at the IPTC meeting in Amsterdam this past March.  The bit about Connect is quite far into his presentation.

The other videos here are quite informative too...

@Leaf: I'm not sure if this is the most appropriate forum for this post, feel free to move it if necessary...
