Metadata Crosswalks on schema:LearningResource

Dataset

This dataset contains the files corresponding to five crosswalks using schema:LearningResouce as reference point. The crosswalks were done during tow hackathons in 2026. The first hackathon organized by ZB MED Information Centre for Life Sciences on June 2025, supported by the NFDI4DataScience (part of the German National Research Data Infrastructure -NFDI), Quadriga Competence Center, and DiscoRSE. The second hackathon corresponds to the hackathon project "On the path to machine-actionable training materials" part of the German BioHackathon on December 2025 and supported by ELIXIR Germany and deNBI.

A crosswalk is a spreasheet where a target resource is compared and mapped against a reference point. Our target resources where:

• Bioschemas TrainingMaterial profile [1]. An extension of schema.org LearningResource developed by the Bioschemas community for life-science training.
• MoDALIA ontology [2]. The ontology used by the educational portal DALIA, developed within the DALIA project for cross-domain.
• Skills4EOSC FAIR-by-Design [3]. A mtehodology providing guidelines for trainers to create FAIR training materials.
• DINI/nestor Metadata Schema for RDM Training Materials [4]. A community-developed schema targeting research data management training.
• Allgemeines Metadatenprofil für Bildungsressourcen (AMB) [5]. A general metadata profile for educational resources built on top of schema.org

Crosswalks were done following the instructions below:

• Please make a copy of this template on this same folder.
• This template uses LearningResource as a reference point. It follows the hierarchy structure from schema.org
• Rename the copied file as "CrossWalk - <resource> - <your name(s)>"
• You can work on the crosswalk on your own or with a colleague. If you work with a colleague, there are two options, (i) one person creates the crosswalk and the other person reviews it, and (ii) both work together and decide how to do so.
• Fill in the provenance and general information for the crosswalk on the Tab "Provenance" (including the mapped resource)
• Start working on the crosswalk. If you find elements in the analyzed resource that are not covered by the reference source, please add rows at the end below "Properties only in the target resource".                                
• Only the section "Mapping to target resource" is mandatory. The other two sections "Additional info about target resource" and "Comments" are optional.
• Once your crosswalks are completed, please rename the file as "Completed CrossWalk - <resource> - <your name(s)>"s
• "Do you have questions? If you have trouble understanding the instructions or unsure whether a new resource you would want to add fits to the purpose, please let us know
• If your question is something along the lines ""how do I map this property?"" we cannot help you with it as we want the crosswalks to be worked independently and free from the chairs influence. We would suggest you add a comment to the actual crosswalk."

During the first hackathon in June 2025, we tried to aligned the mappings to the Simple Standard for Sharing Ontological Mappings (SSSOM) [6] methodology but rather than helping, it generated questions and doubts that were not totally sorted out among the participants so we decided not to include them. SSSOM mainly targets mappings between ontology classes rather than properties coming not only from ontology but a variaty of resources. Using SSSOM to map properties remains an open issue that we could tackle in the future.
