Thomas Meehan

The document serves as an introduction to linked data, emphasizing the importance of utilizing URIs for naming and linking data in a meaningful way. It discusses standards such as RDF and SPARQL and demonstrates the application of linked open data through examples, including the creation of RDF statements for literary works and their authors. Additionally, it touches upon various serialization formats for representing data and their implementations in websites like WorldCat.

linked OPEN data
The Web of Data • Use URIs as names for things • Use HTTP URIs so that people can look up those names. • When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL) • Include links to other URIs so that they can discover more things. Tim Berners-Lee (2006)
