Presentation: "Using Hypermedia Services for System Integration"

Track: Building Systems With REST

Time: Thursday 16:50 - 17:50

Location: Henry Moore Room, Fourth Floor

Abstract:

You have a bunch of systems you need to integrate with one another. But each system also needs to evolve. So how do you tie things together to achieve your goal, but not tie them so tightly that they have no room to move? The goal of this session is to consider how hypermedia can be used to address this long standing problem. The talk focuses on a mix of theory and practice, presenting protocol state machines as a way to model interactions, and exploring how they can be used to support system evolution. Lessons learned from applying these ideas in a range of industries will also be shared.
