This lecture briefly covers the history of human communication up to the present day and then seeks to answer the question, "How best can we create a true Web of Data"? The speaker asks whether ontologies are really the best approach, then explains class-based vs. prototype-based programming languages. Also discussed the difficulties of combining open and private data.

- Differentiates hierarchical document models (eg, XML) and graph models (RDF).
- Understands how an RDF class (named set of things) fundamentally differs from an object-oriented programming class, which defines a type of object bundling "state" (attributes with data values) and "b
- Knows that the word "ontology" is ambiguous, referring to any RDF vocabulary, but more typically a set of OWL classes and properties designed to support inferencing in a specific domain.

- Understands that Linked Data (2006) extended the notion of a web of documents (the Web) to a notion of a web of finer-grained data (the Linked Data cloud).
