- Statements can be modeled (mathematically) with:
						- Resources: an element, a URI, a literal, …
- Properties: directed relations between two resources
- 
              Statements: “triples” of two resources bound by a property
									- usual terminology: (s,p,o) for subject, properties, object
 
 
- 
          RDF is a general model for such statements
						 - … with machine readable formats (e.g., RDF/XML, n3, Turtle, RXR)
- RDF/XML is the “official” W3C format
