INTERLINK aims to overcome the barriers preventing administrations to reuse and share services with private partners (including citizens) by developing a novel collaborative governance model that merges the enthusiasm and flexibility of grassroot initiatives with the legitimacy and accountability granted by top-down e-government frameworks. To enable this, INTERLINK will provide a set of digital building blocks, called “Interlinkers”, that implement the defined governance model and standardize the basic functionalities needed to enable private actors to cooperate in the delivery of a service. The INTERLINK multidisciplinary consortium will deliver the new governance model and Interlinkers within a technological framework and operational platform based on an open software system leveraging on mobile communications, facilitating the co-production of services between PAs and private stakeholders. The solution will be customised, deployed and evaluated on three use-cases. Lessons learned in the three use-cases will be generalized to deliver a reusable solution across Europe.
