Solid Symposium 2023
Workshop Format
The emphasis of the workshop will be on bringing interested researchers together to discuss issues around Trusting Decentralised Knowledge Graphs and Web Data and making progress in some specific sub areas. As such we will organise three half day sessions:
- Lightning talks/posters on a related topic (see our topics list below).
- A decentralised query planning hackathon. The organisers own tools in this area include Comunica a knowledge graph querying framework over decentralised RDF on the Web from the research group at Ghent University and the federated query engines developed by Maria-Esther Vidal's group at TIB. The Open University's blockchain group will bring its tools for recording and validating RDF on a blockchain.
- A decentralised/personal policy modelling hackathon. Related work here includes the ODRL Information Model (and ontology) and the work of the Data Privacy Vocabularies And Controls Community Group. The workshop organisers have been engaged in both these activities.
Topics for lightening talks and posters
- Decentralising KGs - approaches to decentralising KG schemas and data as well as decentralised hosting and storage solutions
- Decentralising KG querying - including federated querying approaches
- Explainability - for data and KG based decision making. Explainability may be high-level for non-computer science experts (e.g. understanding how their personal data has been used) or be based upon fine grained execution traces (e.g. for detailed verification).
- Trust - decentralised approaches to adding trust to data and KG based applications for individuals, organisations and communities
- Provenance - how can the provenance of decentralised data sets and KGs be handled? How to handle provenance when data sets are combined?
- Decentralised KG data - giving individuals and communities full or a degree of control over their own data
- Reliability, validity, and verifiability - how can we ensure that decentralised data and KGs are valid? How can we verify data within a decentralised KG? How to best ensure the reliability of the data?
- Privacy in decentralised KGs - notions of data controllers and data processors are often an imperfect match to decentralised scenarios? How can we ensure privacy and data rights, e.g. as enshrined in Europe's GDPR legal framework?
- Interpersonal data - handling trust, explainability, and data processing constraints with multiple data subjects within decentralised settings
- Collective/consensual decision making - how can we best allow stakeholders and communities to collectively make decisions based on KGs?
- Distributed Ledgers and KGs - how can Distributed Ledgers support the decentralisation of web data and KGs?

Workshop Format
The format of the workshop will be engineered to facilitate a cross-flow of ideas amongst the participants with the aim of generating a post-workshop white paper. As you can see in the agenda below we will begin the workshop with an invited talk on how Solid pods are being used for decentralised personal data storage and exchange. This will be followed by a number of short talks. After a coffee break we will break out into groups to discuss core issues which are come up. The workshop will close with a short report back.
Monday May 1st (13:30 - 17:00)

Introduction |
| 13:40 |
Invited Talk From Concept to Reality: How the Solid Community is Solving Challenges in Decentralized Personal Data Storage & Exchange
Laurens Debackere - Flemish Government
The Solid Project defines a specification for decentralized personal data storage and exchange. However, implementers of Solid in real-world use cases face significant challenges regarding decentralized trust models and data provenance. In this talk, we will dive into these challenges, discussing real-world use cases and the Solid community's efforts to address them. Attendees will gain a better understanding of how Solid is tackling these challenges and its potential for transforming the way personal data is stored and exchanged on the Web. |

A Decentralised Persistent Identification Layer for DCAT Datasets.
Fabian Kirstein, Anton Altenbernd, Sonja Schimmler and Manfred Hauswirth |

Workshop Format
The format of the workshop will be engineered to facilitate a cross-flow of ideas amongst the participants with the aim of generating a post-workshop white paper. Thus, we will structure the workshop to incorporate the views of workshop participants who will cover a number of key stakeholder areas. After a brief introduction the day will start with a panel covering companies and large user groups who supply or use decentralised web data or KG products. The outcome topics and themes from the panel will then be used to structure 2 round table sessions guided by the workshop organisers. Feedback from both sessions will form the foundation of a post-workshop white paper outlining the main benefits and issues associated with trusting decentralised KGs and web data. A 45-minute demo session will allow participants to showcase any relevant tools. The exact format of the demo session will be determined once workshop participant numbers have been confirmed.
