Curation as Choreography

Social norms as choreography

This article shows that social norms are better explained as correlating devices for a correlated equilibrium of the underlying stage game, rather than Nash equilibria. Whereas the epistemological requirements for rational agents playing Nash equilibria are very stringent and usually implausible, the requirements for a correlated equilibrium amount to the existence of common priors, which we in...

Choreography Synthesis as Contract Agreement

We propose a formal model for distributed systems, where each participant advertises its requirements and obligations as behavioural contracts, and where multiparty sessions are started when a set of contracts allows to synthesise a choreography. Our framework is based on the CO2 calculus for contract-oriented computing, and borrows concepts and results from the session type literature. It supp...

Choreography Rehearsal

We propose a methodology for statically predicting the possible interaction patterns of services within a given choreography. We focus on choreographies exploiting the event notification paradigm to manage service interactions. Control Flow Analysis techniques statically approximate which events can be delivered to match the choreography constraints and how the multicast groups can be optimised...

Choreography Revisited

A choreography models interoperation among multiple participants in a distributed environment. Existing choreography specification languages focus mostly on message sequences and are weak in modeling data shared by participants and used in sequence constraints. They further assume a fixed number of participants and make no distinction between participant types and participant instances. Artifac...
