RDFΒΆ

In the first exercise phase we will get familiarized with the use of IRI, URI, URN and URL identifiers for identifying resources. A foundation of the Semantic Web is the Resource Description Framework (RDF) data model. With it, resources can be described by linking to them information such as other resources and atomic literal data. A semantic RDF graph consists of interlinked resources and literal data.

Then, on the second phase, we create an RDF graph by creating resources and literals using the N-Triples notation. After this, we use the Turtle notation to reate RDF graphs and visualize their structure. The objective is to learn to conceive RDF descriptions as semantic graphs. Additionally we get acquainted with two other ways to represent RDF graphs: RDF/XML and JSON-LD.

In the third phase we practice creating our own data in RDF format.

In the final phase of the first exercise set we learn to create an RDF schema.
