The overall objective of the EPOS SP project is to perform activities ensuring the long-term sustainability of the EPOS Research Infrastructure. During the first reporting period significant results have been achieved according to the specific objectives. To enlarge the number of countries joining EPOS ERIC, the National Authorities Consultation Board (NACB) has been established and already in 2020 Romania, member of the NACB, joined EPOS ERIC. Strengthening financial viability through the harmonisation of in-kind contributions from national projects and funding is crucial to long-term financial sustainability of data and services and a mapping on how countries are supporting EPOS at national level has been performed. In this framework a pivotal result has been the finalization of Collaboration Agreements between EPOS ERIC and the organizations in charge of the governance of the scientific communities (TCS). Activities focused on enhancing the technical sustainably of the TCS-ICS System concerned the improvement of the Integrated Core Service (ICS) in terms of robustness and metadata ingestion while testing the TCS-ICS system. The work carried out within the project is fully aligned with the testing of the ICS-TCS system planned in the EPOS ERIC Strategic Plan. The project succeeded in engaging new communities as the Tsunami Community obtained the official status of EPOS “Candidate-TCS” in July 2021. To foster EPOS readiness with EOSC and FAIR Data, an on-line survey, build on similar questionnaires conducted by other initiatives (Open AIRE and FOSTER), has been performed and it allowed to identify the current level of awareness and adoption of good practices to support open science within the EPOS. The online survey has been complemented by face-to-face interviews with selected TCS to obtain a detailed understanding of the on-line responses. An initial evaluation of tools and metrics for evaluating the FAIRness of EPOS services has been started in consultation with other initiatives including the FAIRsFAIR project that is contributing in developing the Rules of Participation for the EOSC. Strategies to strengthen cooperation with the private sector has been outlined, although the COVID19 fundamentally changed the original action plan. The modified action plan resulted in a set of strategic documents identifying key partners and alternative engagement strategies through virtual communication tools and activities have been performed accordingly. COVID19 also severely impacted activities for promoting data science innovation and developing the global dimension of EPOS. During the reporting period a strategy for collaborating with pan–European research infrastructures and international initiatives and organisations has been developed and a number of key partners have been identified. Due to the COVID19, all meetings, planned in presence, have been performed remotely. Nevertheless, the project succeeded in undertake specific collaboration for data science and e-science innovation within ENVRI (and ENVRIFAIR) and Research Data Alliance (RDA). In addition, collaboration activities have been undertaken to strengthen already established relationships with key European (e.g. EUREF, ESA) and global (e.g Auscope, IRIS, UNAVCO, GEO) initiatives. Relevant ethical implications of existing and future EPOS services were explored by collecting information and perceptions concerning the ethical implications associated with data, data products, and service provision through the EPOS Research Infrastructure. Results obtained through the questionnaire will serve as input and knowledge base to elaborate the Ethics Principles and Guidelines for the EPOS ERIC. Notwithstanding the COVID19 training and outreach initiatives on the EPOS contents and usage have been developed to be available on YouTube. This includes an introduction of EPOS and a demonstration on how to search for data using the EPOS Data Portal.
