Workshop 1: Databus - A Semantic Metadata Catalog

Monday 15:00 - 18:00 at TIB: Vortragsraum/Lecture room, 2nd floor TIB location Technology/Natural Sciences, Welfengarten 1B, 30167 Hannover


Discover the intricacies of the Databus platform in our upcoming workshop at the NFDI4Energy Conference. This session will cover the motivation behind the development of the Databus - a nuanced publishing and versioning platform originally tailored for managing the complex release cycle of the open-source DBpedia knowledge graph.

The workshop will cover the fundamentals of semantic web technology, shedding light on how the Databus contributes to semantic interoperability and the evolving landscape of knowledge representation. Participants will explore the practical applications of the Databus, understanding its adaptability to diverse data sources and formats through real-world use cases.

Practical sessions will focus on navigating the Databus interface and leveraging its API for seamless data interaction. Learn the ropes of publishing, versioning, and accessing data efficiently through the Databus platform.

Moreover, participants will gain insights into creating custom metadata catalogs and crafting precise data requests tailored to their specific needs. The workshop will also guide attendees on deploying their own instance of the Databus, providing autonomy in integrating this powerful tool into their projects.

Join us for a deep dive into the world of efficient, versioned data publication and retrieval. The workshop offers a valuable opportunity for researchers, developers, and data enthusiasts seeking to enhance their data management capabilities. See you at the NFDI4Energy Conference, where we’ll explore the practical dimensions of the Databus as a semantic metadata catalog.

Workshop 2: Making Energy System Research Interoperable With Ontologies

Tuesday 9:00 - 12:00 at the Leibnizhaus in the “Leibnizsaal”


Ontologies enable the digitisation and publication of scientific data in a way that allow reuse, as well as transparency and reproducibility of research results. The use of ontologies is well-established in some research areas, like e.g. biology and biomedicine, to organise, curate and interpret huge amounts of research data. Energy researchers are becoming increasingly aware of the advantages of using ontologies. Several ontologies are being developed in that area of research as of now.

The workshop is a collaboration between NFDI4Energy and the Open Energy Ontology. We will start by giving an introduction on ontologies and the challenges of knowledge management.

We will then present insights into the work of NFDI4Energy in the context of ontologies. This discussion will include an overview on the investigation of existing ontologies for energy and energy system research, as well as our future plans to develop multiple ontologies to cover various aspects of the energy research domain.

To provide a specific example, we will introduce the Open Energy Ontology (OEO), a domain ontology for energy system analysis: What are challenges in this specific domain? How is the OEO structured? Which use cases exist for the OEO? Finally, we will learn about accessing the OEO with different tools and take a look into the ontology development process.

Workshop 3: How to Bring Research Data Management into the Field?

Tuesday 9:00 - 12:00 at the Leibnizhaus in the “Karmarschraum” (1. floor)


Developing Clever Outreach Activities for NFDI4Energy

In the Platform Economy, the value of a platform highly depends on the number of people using the provided infrastructure. This principle extends to the envisioned Research Data Infrastructure for Energy System Research within NFDI4Energy. Therefore, early engagement in outreach is crucial as it establishes a foundation for building a robust and informed community, fostering long-term interest and collaboration. Initiating outreach efforts early ensures that stakeholders and the public are well-informed, creating a solid support network that can significantly enhance the impact and sustainability of NFDI4Energy. However, developing Outreach Activities demands a strategic and thoughtful approach and is often confronted with various challenges.

Therefore, the goals of this workshop are:

  1. Gain an Overview: Understand the outreach strategies of other consortia and assess the current status within NFDI4Energy.
  2. Identify Challenges and Raise Awareness: Recognize challenges in implementing Outreach Activities.
  3. Develop Clever Outreach Activities for NFDI4Energy:
    • How can we tackle the challenges?
    • What activities should we focus on?
    • How can everyone contribute?

No prior knowledge is required, making this workshop accessible to all. While extending a special invitation to the energy research community actively involved in outreach activities, the workshop welcomes participants from all backgrounds.

Workshop 4: Research Software Engineering in Energy Research: Exploring Frameworks and Practices

Tuesday 9:00 - 12:00 at the Leibnizhaus in the “Kerstingzimmer” (2. floor)


Join us for an engaging workshop exploring the intersection of research software engineering and energy research. In this session, we will delve into two powerful frameworks, mosaik and VILLAS, and discuss their applications in energy research contexts.

The workshop will kick off with an introduction to the mosaik framework, a versatile tool designed for simulating and analyzing complex energy systems. Through a comprehensive overview, participants will gain insights into how mosaik facilitates the modeling and simulation of energy scenarios, enabling researchers to explore various strategies and technologies in a virtual environment. Following the mosaik introduction, we will shift our focus to the VILLAS framework, another powerful resource created to support energy systems research. Participants will learn about VILLAS’ capabilities in enabling co-simulations, its integration with hardware-in-the-loop setups, and its potential for advancing energy research through innovative simulation techniques, like Geographically Distributed Real-Time Simulation (GD-RTS).

Throughout the workshop, we will engage in discussions on software engineering practices within the research community. From best practices in code development to the importance of reproducibility and sustainability in research software, participants will have the opportunity to exchange ideas and insights on enhancing the quality and reliability of software tools in energy research.

A highlight of the discussion will be the exploration of the Open Energy Platform and its approach to software engineering. We will examine the platform’s strategies for addressing challenges such as financing, continuity, and community collaboration in the development of research software, offering valuable lessons and perspectives for the wider research community.

This workshop is designed to be inclusive and accessible to all, with no prior knowledge required. Whether you’re a researcher looking to enhance your software engineering skills, a developer interested in the energy domain, or simply intrigued by the intersection of technology and energy, this workshop promises to be a stimulating and informative experience.
