Solid symposium aims to gather early adopters from companies, researchers, and the community to discuss Solid, a specification enabling secure data storage in decentralized data stores. The symposium is scheduled for May 2-3, 2023, in Leuven, Belgium.
Prof. Dr. Steffen Staab will serve as a keynote speaker, addressing the audience on shapes for sharing between graph data spaces. Here is the abstract of the talk:
Data spaces in distributed environments should be allowed to evolve in agile ways providing data space owners with large flexibility about which data they store. Agility and heterogeneity, however, jeopardize data exchanges because representations may build on varying ontologies and data consumers may not rely on the semantic correctness of their queries in the context of semantically heterogeneous, evolving data spaces. Graph data spaces are one example of a powerful model for representing and querying data whose semantics may change over time. To assert and enforce conditions on individual graph data spaces, shape languages (e.g. SHACL) have been developed. We investigate the question of how querying and programming can be guarded by reasoning over SHACL constraints in a distributed setting and we sketch a picture of how a future landscape based on semantically heterogeneous data spaces might look like.
