These slides appear to have been used for a course in Database Management Systems at the University of Toronto, but contain material which the creator attributes to other authors. The first part covers the "Web of Documents vs. Web of Data". The second part covers the RDF framework. Later sections cover Linked Data Principles and Linked Open Data. Contains examples of Linked Data applications and mashups.

- Distinguishes the RDF abstract data model and concrete serializations of RDF data.
- Knows the "five stars" of Open Data: put data on the Web, preferably in a structured and preferably non-proprietary format, using URIs to name things, and link to other data.
- Knows the origins of the World Wide Web (1989) as a non-linear interactive system, or hypermedia, built on the Internet.
- 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).
- Knows the subject-predicate-object component structure of a triple.
- Understands that URIs and literals denote things in the world ("resources") real, imagined, or conceptual.
- Understands that a SPARQL query matches an RDF graph against a pattern of triples with fixed and variable values.
