i dont have any reference. its just i was trying to understand layers of semantic data and this came up in my mind... :) On Tue, Dec 16, 2008 at 9:14 PM, Knud Hinnerk Möller <knud.moeller@deri.org>wrote: > Hi, > > I'm not sure about the discovery part - that seems to be more a meta-layer > with data describing linked datasets (VoiD [1]).
