The French project OpenPaaS aims at providing a social and collaborative platform that supports inter-organizational collaborations. This platform is a social network in which subscribing organizations are defined by their profiles (i.e. their capabilities). In response to a collaboration opportunity suggested by an organization, the IT system intends to automatically deduce a corresponding inter-organizational process, meaning that it enables simultaneously (i) the discovery of the collaborative partners and (ii) the building of a collective business process model. This paper aims at describing the interactions that take place first, between the system and the users and second, within the system between the IT components. It also provides an overview of two specific reconciliations in the context of such a design of emerging networks: (i) functional versus non-functional and (ii) business versus technical.
