The OS II project aims to make maximum use of cross-disciplinary universal solutions developed within the IPs EOSC-CZ project (CZ.02.01.01/00/22_004/0007682) and the National Repository Platform for Research Data project (NRP – CZ.02.01.01/00/23_014/0008787), such as the National Metadata Directory (NMA), services of the EOSC CZ Training Center, hardware infrastructure, storage capacities, software tools, repository platforms, or the "catch-all repository." The OS II project builds upon these by integrating discipline-specific elements, such as metadata models based on international data description standards for particular scientific domains (e.g., clinical, archaeological, physical, or environmental data).

DELPHI Pilot Mini-project: Practical Testing of the Repository Platform
In line with the objectives of the Open Science II project (within the Technical Architecture TKA6 – Physical Sciences), the Institute of Physics of the Czech Academy of Sciences (FZU) is implementing a pilot mini-project focused on data from the DELPHI experiment. The project is being carried out from December 1, 2025, to February 28, 2026.
This mini-project serves as a key testing scenario for integrating field-specific physical data into the newly emerging infrastructure.
- About DELPHI Data: The DELPHI experiment collected data at the LEP accelerator in CERN between 1989 and 2000. Following the 2024 release of these unique data on the CERN Open Data portal, we are now creating a second, independent copy at FZU within a newly developed repository.
- Technical Goals: Data from DELPHI are ideal for testing the limits of the Invenio repository platform, upon which the new system is based. The datasets range from small single-file sets to massive collections exceeding 1 TB and containing thousands of files.
- Standardization and Metadata: The project focuses on practical procedures for creating metadata descriptions and implementing Persistent Identifiers (PIDs) to ensure long-term discoverability and traceability of the data.
The results of this pilot will be summarized in a final research report, which will document the procedures and define the platform's limits for storing extensive physical datasets within the developing national ecosystem.
