Automatically update DCM keywords?

Hi all,

I'm looking to see if there is a way that I can update a list of DCM keywords on an automatic basis? Are they stored on the server in an XML file or elsewhere? If I edit this file to add/remove keywords, will these changes be propogated to endpoints etc?

I have a series of text files, that I intend to schedule as an EDM source, but for a couple of them, I would like to schedule as a DCM source to allow for Endpoint Prevent actions.

Thanks,

Nic
