Workshop Overview

Dataspaces have emerged as frameworks that facilitate seamless and trusted data sharing and have recently received attention from politicians, researchers, and practitioners. Efficient data sharing within dataspaces requires semantic interoperability, for which the Semantic Web community has a long history of developing RDF-based solutions.

The Semantic Web Dataspaces (SDS) 2025 workshop aims to foster collaborative efforts to develop semantic methods and solutions tailored for dataspaces. The workshop will improve the expressiveness and standardization of semantic methods and solutions for dataspaces, facilitate the development of shared semantic resources for dataspaces, explore the integration of semantic technologies into dataspace architectures, and promote the adoption of semantic approaches in dataspace implementations. The SDS 2025 workshop will serve as a platform to bring together a diverse community of researchers and practitioners in this area. Through engaging discussions and collaborative efforts, the workshop aims to advance the state of the art in semantics for dataspaces.

Dataspaces have gained traction thanks to the European Data Governance Act (DGA), particularly but not exclusively in Europe. It defines terms such as data and service providers, and is a regulation aimed at promoting fair and equitable data use and establishing a framework for data governance within the EU. The DGA aims to increase trust in data sharing, expand the availability of data for reuse, encourage the development of common dataspaces, and promote the use of data for good. The DGA will impact various sectors, including data providers, researchers, businesses and citizens. Other examples include the movement to establish national and international research data management infrastructures, such as the European Open Science Cloud, the NFDI, and others. The adoption of the FAIR Data notion, which originated from the semantics community, for national and international dataspaces has paved the way for the widespread adoption of semantic technologies. For example, the European Union is spending 4-6 billion Euros to establish dataspaces and has already confirmed that dataspaces must be FAIR. Therefore, we believe that dataspaces are extremely relevant to the Semantic Web community and will have a huge impact on many application domains. This workshop will be highly interactive and communicative, with formal presentations and extensive discussions.



Topics of Interest

The topics of this workshop aim to discuss both conceptual definitions and actual implementations of dataspaces, and to promote the role of the Semantic Web in these. The main topics of this workshop include but are not limited to:

Conceptual Perspective: State-of-the-art Implementations: Semantics for Dataspaces:


Submission

Important: Integration with the W3C Dataspaces Community Group: To foster collaboration and create a lasting impact, authors must align their work with the ongoing efforts of the W3C Dataspaces Community Group, as documented in the GitHub issues repository. This integration will promote consistency, reusability, and collective progress in addressing the core challenges of dataspaces. Authors are required to identify which generic challenge their paper addresses within this repository, and explicitly highlight this in their paper. If the challenge is not listed, they must contribute by adding it to the repository. Use cases are encouraged but must also be documented in the GitHub repository to ensure they contribute to a shared knowledge base. Please note that papers that do not clearly integrate with the W3C Community Group’s ongoing efforts, including the identification of a relevant challenge or use case in the repository, may be subject to desk rejection.

Please submit your contributions via EasyChair: https://easychair.org/my/conference?conf=sds25

We welcome the following types of contributions (see “Rules for papers in the proceedings” at CEUR-WS for more information). All page limits include references.

Strictly follow the rules for LLM generated text and AI assistance in general by the ESWC guidelines and the CEUR-WS guidelines.

Workshop papers must be self-contained and in English. They should not have been previously published, should not be considered for publication, and should not be under review for another workshop, conference, or journal. We use a traditional peer review process, so blind submission is not required. The PDF files must have all non-standard fonts embedded. Papers will be evaluated according to their significance, originality, technical content, style, clarity, and relevance to the workshop.

This year we are partnering up with the ENDORSE 2025 conference in Brussels the 8 and 9th of October. If you’d like to also present your work, in case it is accepted at SDS25, at ENDORSE2025, you will be able to indicate this in EasyChair.

Anikó Gerencsér: Supporting Data Spaces through EU Vocabularies: Tools, Challenges, and Collaborative Solutions

Abstract:
What if all the European Data Spaces spoke one metadata language, instead of relying on multiple standards? Despite the standardisation efforts, the Data Spaces still remain segmented: the lack of federated vocabulary hubs and unified metadata representation impedes data discovery and interoperability. In this keynote, I will argue that common controlled vocabularies aren’t just nice-to-haves: they are the foundation of discoverable, sustainable, and maintainable Data Space ecosystems. Drawing from the open challenges of federated vocabulary hubs, semantic metadata representation, and data discovery, we will explore the available vocabularies, tools, and services provided by the Publications Office of the European Union. Building upon these assets and platforms, I will provide insights into our contributions to European Data Spaces across sectors like Mobility, Legal, Health, and Cultural Heritage. In this talk, I will highlight the existing gaps and challenges and discuss ongoing efforts toward enhancing data discovery and strengthening federated vocabulary hubs for improved semantic interoperability across Europe’s Data Spaces.

Speaker Bio:
Anikó Gerencsér holds a Master`s Degree in Library and Information Science and a PhD in Italian Literature from the University ELTE of Budapest. Since joining the Publications Office of the European Union she is working in the field of metadata standardisation and Linked Open Data management. As a team leader of the Reference Data team she coordinates the maintenance of taxonomies, thesauri, ontologies and authority lists and their publication on the EU Vocabularies website. Her particular area of interest is the development of controlled vocabularies and the harmonisation of reference data management across European institutions. Her team is actively collaborating with Data Spaces by providing reference data maintenance solutions and publication services, data modelling according to Semantic Web standards and creating alignments between controlled vocabularies. She is involved in the optimisation of the thesaurus management tool VocBench, particularly with regard to the analysis of users` needs and the improvement of collaborative and customised features.



Participation and Publication

The ESWC 2025 is a 100% in person conference. All presenters (keynotes, papers, etc.) need to be physically present, no virtual presentations are allowed. We however encourage additional participants to join the workshop physically or virtually.

Workshop papers will be included in an Open Access publication all indexed by all relevant services such as Scopus or Google Scholar. Pre-prints of all contributions will be made available during the conference.

Diversity as Key for Innovation

We believe that research and innovation is enriched and furthered by a multitude of perspectives. Hence, we want to create an inclusive, respectful workshop environment. We invite all individuals to participate regardless of age, education, ethnicity, gender, national origin, religion, sexual orientation, physical ability, physical appearance, or gender presentation. This applies to all aspects, for example, we welcome all operating systems, quality of computer hardware, open-minded political orientation, and appropriate English skills. Inclusion drives us forward every day.
