Application Development Software

Almost every presentation i see about WebCenter and UCM, people tell me that from PS3, content server profiles are made available in WebCenter. I have browsed both the administration guide as the developers guide but i can't find a piece of documentation about it.

When i add a document service taskflow to my page and i want to upload a file, i only get the "browse" button and a field for a description. There does not seem to be an option to select a profile. The documentation also states that you can select the profile when you update th metadata in webcenter. This is also something i haven't found yet...

The taskflows seem generic so they work with UCM, Oracle Portal and a local directory so it seems normal that there is no option for selecting a profile.

Does anybody tried exposing profiles in webcenter or has some documentation on how do to this? To me, this seems like a very important feature but i haven't figured out how to make it work..
