+	- "The RDF data model is similar to classical conceptual modeling approaches (such as [[entity–relationship diagrams]] or [[class diagrams]]). It is based on the idea of making statements about resources (in particular web resources) in expressions of the form subject–predicate–object, known as triples. The subject denotes the resource, and the predicate denotes traits or aspects of the resource, and expresses a relationship between the subject and the object. "
+	- "For example, one way to represent the notion "The sky has the color blue" in RDF is as the triple: 
+  	- [[sky]] [[has the color]] [[blue]].
+  	- Or [[sky]] [[color]] [[blue]]?
+  	- "Therefore, RDF uses subject instead of object (or entity) in contrast to the typical approach of an entity–attribute–value model in object-oriented design: entity (sky), attribute (color), and value (blue)."
