Benefits of persistent identifiers (PIDs) for dataset elements

The NFDI KonsortSWD Measure TA.5-M.1 "Enhancing PID services as a base for a FAIR data infrastructure" aims to assign persistent identifiers on attributes, such as specific variables, instead of only on a dataset and study level. At this presentation, we demonstrate how the service is flexible and allows other data formats, including new attribute levels at the further stages, such as survey questions, audio and video data fragments, a selected part of an image, or any digital object elements that register data throughout the various knowledge subject fields. In this sense, further applications of the PID service at other attributes than variables require metadata fields to be foreseen accordingly. Besides the PID registration service for variables available through da|ra (the DOI registration agency for research data in Germany), all code produced within this measure will be made available as open-source software.
The service is part of the KonsortSWD project deliverable (Persistent Identifiers for Variables - KonsortSWD Task Area 5: Measure 1), NFDI funding number 442494171. PID Service report https://doi.org/10.5281/zenodo.6397367.
