Aligning the HOSA with EOSC

The European Open Science Cloud (EOSC) and the Higher Education Sector Architecture (“Hoger Onderwijs Sector Architectuur”, HOSA) are both initiatives focusing on strengthening the collaboration across stakeholders and sectors at European and national levels. This report discusses the alignment of HOSA with EOSC on the level of principles, stakeholders, governance, platform architecture, platform core components and services offered through the platform. It has been developed through a series of workshops between, the Enterprise Architects of SURF, CITO of GEANT, and the author. It also provides an overview of international architecture and platform initiatives which are of interest to SURF and its members. Finally, it makes recommendations and proposes the next steps. From the discussions during the workshops with the enterprise architects, and in developing this report, it can be concluded that HOSA and EOSC are very similar at the level of aim, principles, stakeholders, and architecture design. While the main objective of HOSA is to support higher education and research in the Netherlands, including access to international platforms, the primary objective of EOSC is to support researchers and research communities from a European perspective. The main differences between HOSA and EOSC are in the targeted audiences and the current state of practice.
