For an effective outreach to stakeholders and to disseminate project results an appropriate communication and outreach strategy is a premise for each project. The CORBEL communication strategy is based on an extended stakeholder analysis in which the CORBEL consortium identified project-relevant stakeholders and rated their power to support as well as their interest in the project. Described stakeholders were allocated to different categories, i.e. Allies, Supporters, Latents and Bystanders to coordinate the envisaged communication and outreach activities. The main focus for communication will be on the three most important stakeholder groups a) user communities, b) policy makers and c) research infrastructures (RI). They will be addressed preferably in a direct consultancy (face-to-face meeting, virtual meetings etc.) and via web-based communication (project website, newsletter etc.). As CORBEL aims to establish a framework of offers to serve the users’ needs, it is essential that relevant information on envisaged/established services is transported to the outside. Messages should be precise and simple so that users not familiar with the complex structure of RIs are able to understand. Public relations material will be elaborated and be available for all participants. It must be emphasised that CORBEL is not to be seen as a competitor for the participating RIs – in contrary, it will act as an amplifier of their outreach.
