In this paper we introduce Subjective Communication, a new interaction model for CAS and generalizing the attribute-based communication introduced in the AbC calculus. In this model, a message is broadcasted to every process, but each process can view the very same message in different ways, depending on its attributes. To formalize this model, we introduce SCC, the Subjective Communication Calculus, for which we propose two semantics: Direct SCC, particularly useful when dealing with an edge computing communication paradigm, and Indirect SCC, more suited to a cloud-centric model. We then introduce a stateless bisimilarity for our semantics, which we prove to be a congruence.
