Abstract: We study several properties of an operation which combines two net systems by identifying local states and synchronizing events according to morphisms towards an interface. We propose this operation as a tool for modular system design, where different components are required to comply with a shared interface, or protocol of communication. We prove results on the preservation of structural properties, expressed as invariants, and of behavioural properties, in particular of deadlock-freeness.
