Description
EOCS-CZ activities include the creation of several data repositories for various scientific fields. The repository for High Energy Physics and Astroparticle Physics is currently under construction. Data from the LEP experiment DELPHI, already preserved in the CERN Open Data Portal, serve as the first use case for the new repository. The motivation is to maintain an additional copy of these valuable data in a geographically distinct location, to test the performance and limits of data access at the current site, and to compare them with those of the new repository.
The new prototype data repository is based on the Invenio framework. This prototype explores an experiment-agnostic approach to publishing preserved HEP (and other) data. The repository technology is conceptually aligned with but independent from the CERN Open Data portal. We discuss the current status of the upload (work in progress), metadata modelling choices, PID options, and lessons learned when adapting a general-purpose digital repository to large-scale HEP datasets.
