EU Internet of Things Architecture Project

I was pointed to this site which reports on the completion of an EU project on IOT architecture.   I like its form.   Its first goal: " ... an architectural reference model for the interoperability of Internet-of-Things systems, outlining principles and guidelines for the technical design of its protocols, interfaces, and algorithms; ... " .  Can anyone point me to to related and up to date work in Europe or elsewhere I can reference for an ongoing study?
