I'm afraid I don't have the Dutch sentence, my supervisor wrote it in English straightaway but I think we should come up with something better than "overarching" thanks for the suggestions so far!

please post the full sentence in Dutch it's hard to see what the actual context is with so much confusing English

Willem Wunderink Sep 2, 2011:

master or corporate - depending on context From a technical point of view Alexander's suggestion for 'master website' is correct. In a more commercial context I would say that 'corporate website' is the most common expression that needs no further explanation.
So, Fabriziat, for you to decide what's most appropriate here! :-)
