This article examines the European Commission's efforts to create a community of practice among e-government practitioners via the epractice.eu project, focusing on knowledge sharing and good practice exchange. Using theories such as boundary objects and communities of practice, the study explores the perceptions and roles of various actors involved, highlighting challenges and success factors in facilitating knowledge exchange across Europe. The case study reveals that practitioners often identify more with localized communities rather than a broader European one, emphasizing the need for effective management of diverse perceptions to enhance collaboration.
