An extensive slide presentation covering the key components that support RDF: the graph model, the triple statement, and URIs. Also discusses the Web of Data and the principles behind Linked Data (including Open Data). The SPARQL query language is given a high-level overview, as is how inferencing can be achieved using RDF Schema and Web Ontology Language (OWL) or Simple Knowledge Organization System (SKOS). At key points the presentation stops so that the audience can engage in group exercises (prompts included).

- Knows Simple Knowledge Organization System, or SKOS (2009), an RDF vocabulary for expressing concepts that are labeled in natural languages, organized into informal hierarchies, and aggregated into co
- Knows that anything can be named with Uniform Resource Identifiers (URIs), such as agents, places, events, artifacts, and concepts.
- 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 subject-predicate-object component structure of a triple.
- Understands the RDF abstract data model as a directed labeled graph.
- Understands that a SPARQL query matches an RDF graph against a pattern of triples with fixed and variable values.
- Understands the principles and practice of inferencing.
