Workshop Overview

In recent years, multiple dataspace initiatives were formed and are growing in both implementation and memberships. Dozens of individual dataspaces and use-cases are arising in their context, as listed in the International Data Spaces Association’s "Data Space Radar" and Gaia-X’ initial list, and even more from other initiatives. The European Union pushes this trend even more by including dataspaces as key element in their data strategy and spending 4-6 billion Euros on establishing these in various domains. The main challenges of this trend on dataspaces are twofold. First, no common definition of dataspaces and their core components exist, which complicates interoperability and FAIRness even at conceptual level. This probably produces isolated solutions tailored to specific use-cases only. Second, the various arising dataspaces in the wild follow different goals and have individual implementations and technology readiness levels. The lack of reusable core components forces stakeholders to reinvent these and leads to diverging implementations and therefore high costs.

The workshop intends to bring together people interested in dataspaces and the role of semantics in these, who may be from different communities such as dataspace drivers, law and policymakers as well as the researchers from the Semantic Web community. Since members of these different communities rarely have chances to interact, we design the workshop to be highly interactive and communicative. We aim at a full-day workshop with ⅔ formal presentations and ⅓ collaboration using the Open Space technique. This approach enables us to identify promising topics for collaboration and follow-up activities by enabling a dynamic agenda driven by the participants’ shared interests.

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:

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.
