This workshop is about enabling semantic technologies for data sharing. Data sharing is an important aspect to enable data-driven decision support systems, more efficient supply chain processes, improved collaboration between business partners and even new business opportunities. In our current times, data needs to be FAIR (Findable, Accessible, Interoperable and Reusable) and data sovereignty is an important aspects. Interoperability agreements and technologies are needed for legal-, organizational-, technical- and semantic interoperability. This workshop focuses on semantic interoperability for data sharing, e.g. how vocabularies/ontologies can be (re)used for API design, data discovery and automatic transactions.
