Semantic Web and Linked Data

This Guide provides access to Semantic Web and Linked Data resources, vocabularies, use cases, and tools.

About the Semantic Web

The Semantic Web provides for the ability to semantically link relationships between Web resources, real world resources, and concepts through the use of Linked Data enabled by Resource Description Framework (RDF). RDF uses a simple subject-predicate-object statement known as a triple for its basic building block. This provides a much richer exploration of Web and real world resources than the Web of Documents to which we are accustomed.

Welcome!

The Semantic Web represents the next generation of Web technology as envisioned by Tim Berners-Lee and led by the World Wide Web Consortium (W3C). This Web of Data enables the linking of data sets across data silos on the Web by providing for machine-to-machine communication through the use of Linked Data. This Guide provides resources to use and implement this technology.

LINKED OPEN DATA (LOD) CLOUD

About the LOD Cloud

The diagram on this page is a visualization of Linked Open Datasets published in the Linked Data format as of April, 2014. The large circle in the center is Dbpedia, the linked data version of Wikipedia. Click on the diagram to learn more about the diagram, licensed and open linked data, statistics about the datasets in the diagram, and the latest version of the LOD Cloud. As of June, 2018, you can view Sub-CLouds by subject area.
