Most (if not all) Enterprise Architecture Frameworks I’ve found pitch Enterprise Architecture as a layered thing. What is not always common, though, is the quantity of those layers - and what they are. Here’s a cross section of sources.
UAF doesn’t really call them “layers”. Instead they are based around “domains”, which have various “aspects”. Frankly UAF seems overly complicated.
