Semantic Web and Linked Data

This Guide provides access to Semantic Web, WIkidata, 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.

I like feedback!

Please contact me! Send an email to: Rhonda Super.

If you are suggesting an additional resource, please provide the following information:

  • Title of the resource, the format, and any other pertinent information
  • If the resource is online, please provide the web address
  • If it is a book, please provide the title, ISBN, and author(s)


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.
