Contract-Driven Implementation of Choreographies [chapter]

Mario Bravetti, Ivan Lanese, Gianluigi Zavattaro
2009 Lecture Notes in Computer Science  
Choreographies and Contracts are important concepts in Service Oriented Computing.  ...  Exploiting some of our previous results about choreography projection and contract refinement, we show how to solve the problem of implementing a choreography via the composition of already available services  ...  We also thank the members of the SENSORIA project for numerous insightful discussions about choreography and contract languages.  ...

Choreographies in the wild

Massimo Bartoletti, Julien Lange, Alceste Scalas, Roberto Zunino
2015 Science of Computer Programming  
We investigate the use of choreographies in distributed scenarios where, as in the real world, mutually distrusting (and possibly dishonest) participants may be unfaithful to their expected behaviour.  ...  In our model, each participant advertises its promised behaviour as a contract. Participants may interact through multiparty sessions, created when their contracts allow to synthesise a choreography.  ...  We would like to thank Emilio Tuosto for his (in)valuable advice, and the anonymous reviewers of ICE 2013 for their comments and suggestions.  ...

Towards a Smart Society through Personal Assistants Employing Executable Choreographies

Lenuta Alboaie
2017 Information Systems Development  
The analysis of executable choreographies and their implementation in the real systems led us to the conclusion that it is possible to increase data privacy by using a different kind of automation made  ...  Large organizations and institutions are known to be ineffective in data safeguarding, and since these data are extremely valuable, criminal organizations or foreign governments are often effective in  ...  Verifiable choreographies underlying the implementation of all other executable choreographies model in a transparent way how private data is transmitted between classic organizations.  ...

Object-Oriented Choreographic Programming [article]

Saverio Giallorenzo, Fabrizio Montesi, Marco Peressotti
2022 arXiv   pre-print
These implementations are libraries in pure Java, which developers can modularly compose in their own programs to participate correctly in choreographies.  ...  Given a choreography that defines interactions among some roles (Alice, Bob, etc.), an implementation for each role in the choreography is automatically generated by a compiler.  ...  Examples of choreographies include distributed authentication protocols [OpenID Foundation 2014; Sporny et al. 2011] , cryptographic protocols [Diffie and Hellman 1976] , and multiparty business processes  ...

Sharing Choreographies in OpenKnowledge: A Novel Approach to Interoperability

Paolo Besana, Vivek Patkar, Adam Barker, David Robertson, David Glasspool
2009 Journal of Software  
The framework provided by OpenKnowledge, based on sharing choreographies among actors, allows the representation and enactment of the coordination aspect of guidelines and the discovery of the medical  ...  However, these architectures are still designed and enacted from a centralised perspective: a single process invokes remote services, unaware of being part of a larger, more complex workflow.  ...  This research was partially funded by the European Commission within the 6th Framework project OpenKnowledge (number 027253), by Cancer Research UK and by EPSRC grant EP/F057326/1 (the Safe and Sound 3  ...
