Metadata curation efforts at Kascade Cosmic-Ray Data Centre

Metadata curation plays a pivotal role in advancing the machine-actionability of data, thereby facilitating the fulfillment of FAIR data principles. The KASCADE Cosmic-ray Data Centre (KCDC) has served as a repository for data generated by the high-energy astroparticle physics experiment KASCADE, along with several other research projects, since 2013. Additionally, it functions as an information platform in the field of high-energy astroparticle physics for both the astroparticle community and the general public.

The platform provides users with a diverse set of digital objects. While some of them possess rich sets of metadata (including persistent identifiers such as DOIs and ISNIs), and allow machine access via REST API, efforts to integrate with the broader PUNCH4NFDI Data Portal underscore the necessity of a unified and comprehensive approach to curate a wider range of granted resources. The contribution examines KCDC’s digital resources as Digital Research Products and covers recent developments, with a focus on integrating our curation practices into data-intensive physics communities’ endeavors and the national data infrastructure landscape.
