RDF Data Model
The foundation of RDF is a data model for representing named properties (attributes) and property values. The data model is a syntax-neutral way of representing RDF statements - RDF permits some syntactic variation, so it can be determined whether two RDF statements are equivalent by comparing their data model representations.
The RDF data model consists of three object types:
- Resources - anything described by an RDF expression (web pages, specific parts of web pages, web sites, books,...). Resources are named by URIs.
- Properties - attributes used to describe a resource. Each property has a specific meaning, and defines its permitted values, the types of resources it can describe, and its relationship with other properties.
- Statements - An RDF statement is a specific resource together with a named property and the value of that property for the resource. These three individual parts of a statement are often refered to as the subject, the predicate, and the object.
Example (from [2])
Ora Lassila is the creator of the resource http://www.w3.org/Home/Lassila.
