Enhancing Metadata Workflows and Long-Term Preservation of Research Outputs: Adopting FAIR Principles with Dagstuhl Publishing

In its final report, the EOSC working group on Scholarly infrastructures for Research Software (SIRS) identifies archiving, referencing, describing, and crediting research software as critical pillars for open science and long-term sustainability. Based on these recommendations, Dagstuhl Publishing has enhanced its workflows to improve the publication, preservation, and accessibility of scholarly outputs, particularly supplementary materials such as research software. The extended submission system (DSUB) now enables authors to submit research software alongside their articles. Long-term preservation of the software is ensured by archiving on Software Heritage. The two tools for this, SWH Archive Client and SWH Deposit Client, are available as open source. Metadata is automatically fetched from platforms such as GitHub or CITATION.cff files and manually curated to ensure completeness. A demo is available at http://faircore4eosc.dagstuhl.de/. Furthermore, the collected metadata is published in a collection on the DROPS repository which connects articles with their supplementary materials. This submission process follows FAIR principles and maintains minimum metadata standards: https://drops.dagstuhl.de/entities/collection/supplementary-materials. This presentation will highlight Dagstuhl's solutions, including automated metadata workflows using CodeMeta JSON and manual curation, showcasing a scalable model for software preservation and repository management. We will also explore lessons learned and future directions to advance open science and sustainability.
