A publish/subscribe approach for implementing GAG's distributed collaborative business processes with high data availability

Abstract : With the ever-increasing development of the Internet and the diversification of communication media, there is a growing interest in distributed business process models that focus on exchanged data (or artifact) to control and pilot processes. The Guarded Attribute Grammars (GAG) is one such model; it stands out from the others by the fact that it emphasizes the central place occupied by user decisions during the process execution: it is both data-driven and user-centric. In this paper we present an approach to implementing distributed collaborative business processes modeled using GAG in which communications are done by publish/subscribe with redirection of subscriptions (pub/sub-RS). Pub/sub-RS-which we propose-guarantees high data availability during the process execution, by ensuring that an actor, perceived as a subscriber, will always receive a data he needs to perform a task as soon as it is produced. Moreover, if the data is semi-structured, and is produced collaboratively and incrementally by several actors, its subscribers will be notified as soon as one of its components (a prefix) is produced at the same time they will be subscribed in a transparent way to the remaining components (the suffix).
