One design file in — a production OPC UA server out. Eleven years of them, from the ATLAS cavern to the DUNE cold box.
quasar generates the whole server — address space, device logic, configuration — from a single declarative model. What began as an ATLAS DCS tool in 2015 is now the house style for OPC UA at CERN: every entry in this index is a real deployment, read straight from its public repository.
