Collaborations Workshop 2026 of de-RSE
Searching semantic data management systems and knowledge graphs is a challenging endeavour. Prevalent semantic query languages like SPARQL are difficult to learn and therefore pose a high barrier to widespread adoption among non-technical users.
Large language models (LLMs) provide a promising way to enable researchers without advanced skills in SPARQL or other domain-specific search languages to perform specific data queries that can be used for subsequent analysis and automation.
We have developed an LLM-based query interface for the open-source semantic data management system LinkAhead. Its main component is a translator that converts natural language into LinkAhead’s domain-specific query language, CQL. The component can be used with a variety of open-source, open-weight, or proprietary LLMs.
Hallucination risks are mitigated through a combination of constrained query generation and human-in-the-loop verification. A graphical interface enables users to inspect generated queries in a structured form before execution, reducing the likelihood of incorrect queries being sent to the LinkAhead backend.
This workshop will introduce the design and architecture of the LLM-based translator. Furthermore, we will present validation results and discuss limitations.

HMC Conference 2026
Managing (meta-)data across interdisciplinary research collaborations often involves using a variety of software tools for storage and sharing. Maintaining data accessibility and synchronization between different sites, working groups, and institutes presents a significant challenge. We developed a solution based on the open source software LinkAhead that combines meta data from different repositories into a single research data management system (RDMS). The meta data import tool was created using the extensible crawler framework provided by LinkAhead. This enables us to import meta data from four different repositories and ELN systems used by the Cluster of Excellence 3D Matter Made to Order (3DMM2O). Where possible, APIs of repositories and ELNs can be used to directly upload meta data entries from LinkAhead (e.g., via export to DataCite XMLs). This allows
(semi-)automatic workflows, such as described in the following example:
- A researcher enters meta data in an ELN
- These are imported into LinkAhead by the crawler (possibly enriched
by data from other sources) - They can be sent directly to a repository for publication.
In addition, the RDMS is built in a way that data models and crawler definitions can also be extended and adapted to future requirements by the researchers at any time. Its basic functionality contains a graphical web-interface, as well as an API for automated queries which provides intuitive searching and querying and using meta data from all linked systems.
With Dr. Florian Spreckelsen

Keeping research data findable and accessible can feel like an overwhelming task, especially when multiple data formats, tools, and actors are involved. Where do you even start? It’s time for a data spring cleaning!
In this talk, we will show you simple “spring cleaning” methods for organising your data that you can test out right away. After that, we will introduce you to more advanced approaches to automate the integration of heterogeneous datasets from ELN systems and repositories like eLabFTW or PANGAEA.
This talk takes place as part of the annual Love Data Week.

“Code, Community, Company?! Sustaining Open Source Research Software Through Founding a Company”
Date: Tuesday, 21st October at 11:00 am
Nina Rosnerski and Dr. Alexander Schlemmer
Research software is built with great effort and dedication, but all too often risks fading away once projects end or key contributors transition into other roles. In this talk, we discuss one possible way to address this challenge: founding a company. We will explore under which conditions founding a company can help to ensure long-term maintenance, create reliable structures, and give research software a future beyond short-term funding cycles. At the same time, we want to reflect on tensions resulting from commercial structures, share some of the challenges we faced along the way, and invite discussion about what sustainable models for research software could look like inside and outside academia. Our perspective comes from IndiScale, where we continue to develop the open source toolkit LinkAhead. LinkAhead originated around 15 years ago in the research context under the name CaosDB. In 2019, the core developers founded IndiScale to give the project a sustainable future. Today, LinkAhead is used successfully in a wide range of interdisciplinary research contexts.

FAIR in Action
Too many disconnected research data management tools?
Join us at the FAIR in Action conference on the 01.- 02.10.2025 in Göttingen! The event brings together users, data stewards, and developers from RDM (research data management) communities to explore how to actually make different (open source) RDM tools work together. FAIR in Action is a satellite event of FDM@Campus 2025 an free of charge.


Datenchaos? Keine Ahnung wo die aktuellen Versionen liegen? Ihr seid nicht allein! Wir zeigen euch eine einfache Methode, mit der ihr eine klare Struktur in eure Forschungsdaten bringt – und das so, dass ihr den Unterschied direkt merkt.
Sobald die Basis steht, geht es zum nächsten Schritt: Mit der Open-Source-Software LinkAhead lässt sich euer Forschungsdatenmanagement von der Datenerfassung bis zur Veröffentlichung automatisieren. Ihr bekommt einen Einblick wir ihr Daten in LinkAhead effizient durchsuchen und Verknüpfungen der Daten miteinander nachvollziehen könnt.

We are very much looking forward to spending Girls’ Day 2025 with eight young hackers. Once again, we will be offering an insight into the world of python and the day-to-day work of a software company. Demand was high and places were snapped up in no time at all. So if you are interested in hacking, you should come and have a look here.
And, of course, we will report on how wonderful it was.

How can research data from different sources be effectively managed, linked, and reused? In this session we will give an insight into LinkAhead – a flexible open source software toolkit specifically designed to meet the needs of research data management.
LinkAhead enables the automated integration of different data from different contexts and thus serves as a link between the different steps of the research process – from data acquisition to data analysis and publication. It works hand in hand with other RDM software such as electronic lab notebooks or repositories. We will demonstrate how researchers can efficiently browse their data in LinkAhead’s web interface and trace links between data.
LinkAhead supports researchers in various research areas, grows flexibly with their needs and can therefore be used by individual researchers as well as small research groups or entire institutes.
The workshop is organized by the state initiative Research Data Management Lower Saxony, FDM-NDS. FDM-NDS is a collaborative project under the umbrella of Hochschule.digital Niedersachsen and is funded as part of zukunft.niedersachsen, a funding program by the Lower Saxony Ministry of Science and Culture (MWK) and Volkswagen Foundation.
