HMC Conference 2025 | Workshop 1: Search over Multi-Layer Metadata
11:00 - 13:00
Organizer: Carsten Hoyer-Klick, German Aerospace Center Institute of Networked Energy Systems
Co-organizers: Dr Sebastian Hellmann, InfAI University of Leizpzig; Jan Forberg, InfAI University of Leipzig
Introduction: The SOMMER project (Search over Multi-Layer Metadata for NFDI4Energy Repositories) is an initiative aiming to establish an adaptable, multi-domain metadata catalog to support energy research. Utilizing the existing Databus and MOSS (Metadata Overlay Search System) technologies, the project enhances metadata annotation and search capabilities for diverse datasets in NFDI or HMC contributing significantly to the FAIR (Findable, Accessible, Interoperable, and Reusable) data management goals. The core objectives of SOMMER include refining user interface and experience, fostering community engagement, and enhancing metadata compatibility across various repositories. By incorporating feedback from energy researchers and operators of research data repositories the project intends to create a well-integrated, user-accepted metadata registry. This registry will support various scientific domains while maintaining adherence to recognized standards such as DCAT, SPARQL, and RDF, ensuring interoperability with tools like LDM and TIB Terminology Services.
Within the HMC Conference we want to take a specific focus on operators of data repositories and how they can use databus and MOSS to enhance their visibility and searchability of their data. Through the integration of multiple metadata standards, SOMMER addresses the challenges of diverse data sources, enabling researchers to annotate datasets from a central platform. This approach encourages broad adoption within the energy research community by supporting domain-specific and interdisciplinary metadata needs. Ultimately, SOMMER provides a scalable solution with cross-domain search functionalities with the potential to become a reference model for metadata catalogs within the broader NFDI and HMC framework.
Workshop: Within the workshop we want to introduce the current implementation of Databus and MOSS and collect feedback to improve functionalities and the interface to search for research data.
Agenda:
- Welcome and introduction to Databus and MOSS
- Demonstration of the current functionalities
- Time to experiment with Databus and MOSS
- Discussion on implementation challenges in research data infrastructures
- Next Steps
Please note: This workshop is part of the HMC Conference 2025 taking place in Cologne from 12-14 May 2025. Participation must be in person and is only possible for people who are registered for the conference.
