Workshop 1: Search over Multi-Layer Metadata for NFDI4Energy Repositories (SOMMER)
Tuesday 09:00 - 12:00 at (Mathe (20.30), 0.014)
Description
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 NFDI4Energy, 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, 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.
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 framework.
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.

Carsten Hoyer-Klick
Carsten Hoyer-Klick works at DLR since 2003. His research focus is on research data in different perspectives. Starting with Earth Observation data and contributing to the development of the GEOSS (Global Earth Observation Systems of Systems) for the energy sector. The GEOSS is a federated infrastructure connecting multiple repositories through standard interfaces and catalogs, the ideas were then transferred to energy systems analysis. Within the LOD-GEOSS project Databus and MOSS were established as connecting elements for a federated data infrastructure. He is now active in the Helmholtz Metadata Collaboration and in research data management at DLR within the research fields energy and transport. The SOMMER Project is a joint contribution of InfAI and DLR to NFDI4Energy.
Workshop 2: Refining Metadata for Energy Simulation Software
Tuesday 9:00 - 12:00 at (Mathe (20.30), 0.016)
Description
The workshop aims to gather actionable feedback to refine the metadata schema for energy simulation software. It focuses on engaging stakeholders to ensure the schema aligns with the practical needs of different sub-branches and adheres to FAIR principles (findability, accessibility, interoperability, and reusability). The outcomes will contribute directly to the development of the metadata schema and software registry.
Participants will share how their institutions use metadata or ontologies in energy system modeling, particularly their benefits in improving data exchange, software documentation, and tool compatibility. The goal is to emphasize the role of metadata schemas in facilitating the search for energy research software and creating a comprehensive registry for simulation tools.
An interactive session will involve participants in identifying metadata requirements for their specific areas, such as agent-based simulations and co-simulations. This collaborative effort will ensure the schema addresses diverse sub-branches’ unique needs. The results will be used to evaluate and refine the existing schema to enhance its coverage and usability.
The workshop will help identify key metadata features for various sub-branches, discuss standardization across different areas, and address any gaps in the current schema. The overall aim is to optimize the metadata schema for better discovery, usability, and interoperability of energy simulation tools.

Workshop 3: Introduction of the OEO Foundry for Interoperable Ontologies in NFDI4Energy and the Energy Domain
Tuesday 9:00 - 12:00 (Mathe (20.30), -1.025)
Description
Ontologies enable the digitisation and publication of scientific data in a way that allows reuse, as well as transparency and reproducibility of research results. The use of ontologies in the research area of biology and biomedicine is well-established to organise, curate and interpret huge amounts of research data. Many NFDI consortia develop domain-specific ontologies, and also researchers of the energy domain are becoming increasingly aware of the advantages of using ontologies. The increasing awareness about ontologies leads to an increasing request thereof.
In NFDI4Energy, TA4, the plan is to develop and improve energy-system-related ontologies. These ontologies are all intended to be interoperable with each other, in order to form a comprehensive semantic layer for the NFDI4Energy services.
To tackle the challenge of interoperability, we want to develop common standards and orthogonal scopes for energy related ontologies. Therefore, we take a look at existing initiatives, like the OBO Foundry. We want to apply their ideas and expericenes of over 20 years of ontology work to the energy ontology domain.
In the workshop, we will officially launch an initiative for interoperable energy ontologies (“OEO Foundry”). We will give an introduction to the topic of ontology interoperability and the goals of NFDI4Energy TA4 / Measure 4.6, and the Flex Funds project “Standards and Scopes for Interoperable Energy Related Ontologies”. A first set of development standards will be presented and discussed with the community for adoption into the Foundry.
