Content governance mechanism

I am studying for an exam and there is a sample question like :

You are the Manager of the UN web site, which comprises of a number of sub-sites, in the six official languages, with information prepared and produced by different Departments. You have been asked by senior Management to devise and establish a clear, coherent, workable and acceptable governance mechanism for the entire site which will take into account the different needs of the content-providing De开发者_如何学Cpartments which maintaining a degree of centralization so that institutional branding is not compromised. Prepare an outline for this governance mechanism setting out responsibilities of content-providers, the technical group and the management group

I just stuck at content governance management. I searched the web but not found much. Any hint, idea, document or resource will be a lifesaver for me.

Thanks your help.

I think you should attack this from 2 sides, for governance you could look at models used in open source projects ( http://www.google.com/search?q=open+source+governance ) and for content management entitlements look for user roles ( http://www.google.com/search?q=content+management+user+roles ).
