Anyone can get involved in the implementation of the EOSC Initiative in the Czech Republic through the 12 open working groups. The EOSC CZ Working Groups (EOSC CZ WG) are of great importance because they facilitate collaboration between experts from different fields and disciplines with diverse experience and knowledge in research data management and specific fields. EOSC CZ WG serve as a platform to discuss, collaborate and address specific issues related to the needs of research communities. Each working group focuses on a specific aspect of the EOSC implementation in the Czech Republic, such as core services, sensitive data management, long-term data storage, sustainability, etc.
