The globalised and moving economical environment leads enterprises to develop networked strategies. Such collaborative networks are by now often based on trusted and well known communities and require IT support agility and interoperability. The European Union promotes solutions to support and favor innovative business networks on the basis of an internet of services: these FP6 and FP7 projects results provide a consistent environment (including design, methods and developments related to Enterprise Service Bus (ESB) technology) to support technologically Business Service oriented organizations and the large-scale reinforcement of collaborative business and networked organization strategies. Nevertheless these works are mostly focused on an IT vision without taking into account business constraints. To overcome this limit, we propose a multi-dimensional service-chain ecosystem model, paying attention on service functional and non-functional properties description to support an efficient and consistent business service selection and composition process so that large-scale service based collaborative organization can emerge.
