how do I synchronize labels in iView MediaPro?

hi,
i’ve been trying to do this for a while now, but i can’t find the right way to do it.
i also haven’t found anything in google, o another forums or posts here… so, here’s the thing.
i have one big iView catalogs with about 500 images (just images).
i want to split that catalog into several small parts (manually of course, i want the parts to be specific), and then give that parsed catalog to another person. that person will classify the images in the catalog by labeling them (for example, green for ok, red for not ok).
then that person will give that catalog back to me and here is when the script starts.
i want to sync the labels from the new classified catalog, to the big huge catalog i have.

any ideas on how to do this?
i’m trying to register at the iView forums but the activations is taking a looooong time.
i also tried to steal code… i mean, inspire myself with some of the example scripts, but ended up with nothing…

thanks in advance guys.
best regards.

-Martin.
