Dorothee Kottmeier (AWI - Helmholtz Centre for Polar and Marine Research, Bremerhaven, Germany)10. Harmonisation of Metadata: Closing Semantic GapsPoster
Embedding semantics in research metadata is essential for improving interoperability across datasets and for implementing the FAIR principles. The HMC Hub Earth and Environment is developing a coordinated, community-driven strategy to support the consistent and sustainable use of semantics in Earth and Environment research and to contribute to cross-domain semantic harmonization within the...

It packages data together with associated metadata in a FAIR manner.
For wide community adoption, the format must be tangible for its users.
Programmatic APIs are often insufficient for interactive exploration, on-the-fly editing, and introspection by researchers, data stewards, or... -
Oonagh Brendike-Mannix (HMC/HZB)9. From Minimum Requirements to FAIR and AI-Ready: Assessing Metadata QualityPoster
As staff of the Helmholtz Metadata Collaboration (HMC), we used metadata harvested by HMC services to conduct a cross-provider analysis of how metadata is currently exposed across Helmholtz and to identify systematic issues that affect metadata quality.

The analysis focused on three priority fields that strongly influence discoverability and integration: identifiers, publication date, and... -
David Schimmel (RWTH Aachen University)9. From Minimum Requirements to FAIR and AI-Ready: Assessing Metadata QualityPoster
The concept of FAIR Digital Objects (FDOs) supports good research data management practices. However, the evaluation of compliance with the FAIR principles suffers from uncertainties: the FDO specification allows different implementations. Furthermore, heterogeneous, domain-specific terminologies and ontologies are used in concrete FDOs. Access methods for data and metadata differ among FDO...

Alicia Janz (Forschungszentrum Jülich GmbH)9. From Minimum Requirements to FAIR and AI-Ready: Assessing Metadata QualityDemo Poster
As the volume of research output accelerates, the rigorous validation of scientific publications, and the assessment of their claims, objectives, and reproducibility, have become critical bottlenecks. Traditional manual verification is labor-intensive and unscalable, often failing to keep pace with the growing need for structured assessment. To address this, we introduce a domain-agnostic,...

The German National Research Data Infrastructure (NFDI) BioMed Interest Group unites five NFDI consortia - GHGA, NFDI4BIOIMAGE, NFDI4Health, NFDI4Immuno, and NFDI4Microbiota - to address the distinct technical, regulatory and ethical challenges of research data management (RDM) in biomedical science. These consortia represent diverse research communities, each with their own approach to...

Paolo Graniero (Helmholtz Zentrum Berlin für Materialen und Energie)8. From Harmonisation to Action(ability)Poster
At PVcomB (Helmholtz-Zentrum Berlin), we are establishing a comprehensive data management framework for the outdoor testing of perovskite solar cells. A major bottleneck in materials science is the disconnection between synthesis data and long-term performance metrics. Addressing this, our initiative supports the increasing drive by research groups at HZB and partner institutes to introduce...

Janine Berndt (GEOMAR Helmholtz Centre for Ocean Research Kiel)10. Harmonisation of Metadata: Closing Semantic GapsPoster
Because of traditionally large data volumes and the diversity of acquisition and processing workflows, internationally recognized metadata standards for marine seismic data are still lacking. At the same time, there is a growing need within the geophysical community to harmonise metadata in accordance with the FAIR principles, enabling semantic interoperability, long-term reuse, and emerging...

Domain semantics typically allow to describe things very precisely and with a precise meaning. In many cases, however, not everything that can be said is either true or false, but often true or known only in a limited domain of validity: a certain time span (e.g. the temperature of an object), a spatial domain (e.g. a law), a certain simplification of a theory (e.g. a proportionality...

Saeid Masoumi (Karlsruhe Institute of Technology)9. From Minimum Requirements to FAIR and AI-Ready: Assessing Metadata QualityPoster
Heterogeneous experimental data in modern physics research facilities, such as KARA and FLUTE at KIT, often rely on experiment-specific metadata, making it challenging to define a unified schema for Research Data Management (RDM). We propose an object-oriented approach to address this challenge.

Kristina Fischer (Leibniz-Zentrum für Archäologie)10. Harmonisation of Metadata: Closing Semantic GapsPoster
In object-based research within the humanities, such as archaeology, art history, provenance research or conservation science, metadata describe not only digital files but also help to structure information about real-world cultural heritage. The term "metadata" here encompasses systematised object information on object designation, creation history, provenance and usage. Thus, "Creator"...

Kristina Fischer (Leibniz-Zentrum für Archäologie)10. Harmonisation of Metadata: Closing Semantic GapsDemo Poster
The conservation of cultural heritage combines humanities and natural science approaches with practical work on objects. Conservation activities provide unique insights into materiality, manufacturing traces, as well as damage mechanisms and modifications of an object. Despite their scientific relevance for object-based research, these data are often hidden in narrative reports, neither...

Dr. Klaus Getzlaff (GEOMAR Helmholtz Centre for Ocean Research Kiel)8. From Harmonisation to Action(ability)Poster
Numerical earth-system simulations are often documented and shared on a personal level while details on simulations are rarely easily findable, even within institutions or departments. This is a hurdle for possible collaboration and re-use, especially for non experts and people from other research fields. The publicly available documentation of simulations, if any, is mostly part of a...

Metabarcoding of the 16S rRNA gene is widely used to assess microbial diversity due to its cost-effectiveness and efficiency. However, publicly available 16S rRNA metabarcoding datasets often lack standardized metadata, particularly information on the sequenced hypervariable regions or primers used, which are critical to their accurate reuse. To address this, we present HVRLocator, a...

Andrea Pörsch (HMC@GFZ)10. Harmonisation of Metadata: Closing Semantic GapsPoster
The improvement of data exchange between research communities and public authorities in Germany is frequently discussed. Both the research data infrastructure in the Earth and environmental sciences and the German Geospatial Data Infrastructure (GDI-DE) are highly developed systems. However, the respective communities tend to operate largely within their own domains. This separation is not...

Preparing for beamline experiments often requires providing sample information alongside the proposal, especially for external users who may not be present during the experiment. A standardized form based on a JSON schema simplifies this process: it minimizes follow-up questions through built-in validation and constraints, and directly generates a machine-readable JSON object. This object can...

Knowledge graphs enable the structuring and linking of scientific metadata from heterogeneous sources, supporting advanced search and analysis. Their effectiveness, however, depends on the level of metadata consistency and standardization. Graphs linking high-quality topical information can also be very useful for training tailored LLMs and AI models for specific purposes. With this activity,...

Recent advances in imaging and computational methods have led to a rapid expansion of video-based tracking in the biological sciences. The increased adoption of video tracking assays (VTAs) has created new opportunities and challenges for quantitative analysis across multiple scales of biological systems.

Arctic permafrost soil research is significantly limited by the scarcity of reference data. While increasingly more reference data has been published in recent works, it remains scattered among publications, data repositories and institutional archives. Often, the provided data is highly unstructured, important metadata is missing, and previously synthesized databases are becoming outdated and...

We have developed Timely, a domain specific extension of HTML, that enables the visualization, analysis and subsequent export of metadata-enriched time series data within arbitrary websites. The implementation is based on the W3C standard Web components, so that the extension can be used in all current browsers without installing additional plugins. Web components are user-defined HTML...
