These days, Semantic Web technologies are a well-established standard for publishing data on the Web. More than a decade of publishing and interlinking has made available RDF datasets that exhibit very large sizes (>1 billion triples) and semantically bridge together information from very different domains. Linked Data, the core technology behind Semantic Web, is not a research prototype anymore; it is used in real-world systems and large-scale companies, under various different names (e.g., Knowledge Graphs).
