The implementation resources guide European University alliances and higher education institutions to improve interoperability and make seamless data exchange and student mobility a reality. The practical materials were developed in collaboration with experts from the higher education interoperability working group of the European Digital Education Hub. The resources offer a modular and flexible kit that can be adapted and shaped at the level of higher education institutions and alliances to suit their individual realities and needs. The resources include a number of different types, such as a process guide, stakeholder management resources, a communication product and a workshop package. The resources are designed for specific interoperability use cases of the European Higher Education Interoperability Framework, but users can adapt most formats to other cases.
