Interoperability is the ability of information systems to process, store and exchange electronic documents using uniform technology standards and processes. In the age of the advanced information society, the interoperability of information systems of different organisations, both public and private, is becoming a main factor for the efficiency of the economy. A number of directives of the EC indicate the crucial role of this trend in the development of information society. The EU Digital Agenda, one of the 7 flagships in the Europe 2020 strategy, defines interoperability as a main line of action. One of the questions that comes up when addressing a topic as new as the present one is “Are the necessary skills in place?”. While most European countries have developed excellent legislative frameworks and have set up the necessary institutions for interoperability implementation, the knowledge of the specialized regulations and the necessary skills among the actors involved remain inadequate.The present proposal will improve the knowledge and skills of stakeholders in eGovernment projects across Europe through the development of an innovative e-learning tool based on the consortium’s own state-of-the-art research. Skills and expertise is gathered from a variety of sectors: research, university education, VET, public administration liaison, e-learning and interoperability. Each partner institution is a leading educational/training organization with a vast network among the target groups and the resources to disseminate and exploit the project results effectively and efficiently. The e-course produced will contribute to working adults’ inclusion in lifelong learning, develop new skills and attitudes and help them meet the requirements of the changing environment, improving their employability. The project will play an important part in the development of public services in Europe, both at national and local level and in support of broader cross-national needs.
