We have Subject ID, which defines the kind of information exchanged using messages, and we have Service ID, which defines the kind of information exchanged using RPC. We need a new term that can refer either or both to Subjects and Services. Initially, I thought that Endpoint would be the way to go, but then I realized that it doesn’t work well if one were to view the network as a computational graph, where subjects are edges and nodes are, well, nodes, because the name implies that there is a point-to-point connection whereas the truth is that we can have a MIMO connection.
How do you describe the point where an edge is connected to a node? Anchor?
