The Revised DALIA Interchange Format - New Picklists for Describing Open Educational Resources
Abstract
The scientific infrastructure project DALIA (“Data Literacy Alliance”) aims to index, connect, and make accessible existing learning materials on data literacy. It builds and maintains a platform that encompasses materials for the National Research Data Infrastructure (NFDI), federal Research Data Management (RDM) initiatives, data competence centers, and beyond. Within the platform, the differing requirements of professions, career levels, and disciplines must be considered and integrated. Among these are professors, researchers, students, and professionals from libraries and archives. The disciplines span the full range of scientific fields, such as engineering, natural and life sciences, the arts and humanities. The competency levels on data literacy may also vary.For the linking and integration of the learning resources, DALIA has been developing a knowledge graph. To ensure the interoperability of teaching and learning materials for this knowledge graph, a schematization of their metadata was developed: The DALIA Interchange Format (DIF, currently V1.3) provides a framework for making metadata consistent and smoothly integrable into the DALIA platform.However, the development of picklists presents a complex challenge. While some picklists can be compiled from existing controlled vocabularies, others encounter issues with unclear boundaries. Definitions must be clear, concise, and, whenever possible, refer to a standard. This presentation focuses on the compilation of picklists for the DALIA Interchange Format, aiming to simplify the description and classification of teaching and learning materials.

These can be very hands-on roles involving daily data analysis or roles that are more policy and advising-focused. A data steward facilitates the quality, integrity and access to (meta)data in a manner that is consistent with the appropriate laws and institutional policies, ensuring professional treatment of data throughout all stages of the research project. Data Stewards are an important part of scientific communities, supporting recommended data management practices and supporting researchers in these efforts. Often their roles overlap with those of data managers and other professionals who curate data.
