Business process modelling (BPM) notations describe processes using a graphical representation of process-relevant entities and their interplay.

Abstract

Business process modelling (BPM) notations describe processes using a graphical representation of process-relevant entities and their interplay. Despite the wide literature on the comparison between different modelling languages, the BPM community still lacks an ontological characterisation of process constructs. Purpose of Choreography diagrams have been introduced in the Business Process Model and Notation language 2.0 (BPMN 2.0), one among the most used languages for modelling and analyzing business processes in industry, in order to provide a view on the interaction between participants. Besides the intuitive definition of choreographies as interfaces among participants, the BPMN 2.0 specifications also define choreographies as business contracts among the parties. However, the adop- tion and the diffusion of the business contract nature of choreography diagrams seem to be hindered by the underspecification of the notation, which does not allow to model and formalize constraints and relationships among choreography entities, which would need to be specified in a business contract. In this paper we provide a preliminary investigation of some of the open issues characterizing BPMN 2.0 choreography diagrams when looking at the business contract nature of the nota- tion, by focusing on those related to messages and participants.
