Rdfs schema tutorial. One such extension is RDF Schema.
Rdfs schema tutorial. In addition, RDF also needs a way to define application-specific classes and properties. This language allows one to define semantic characteristics of RDF data. It also extends definitions for some of the elements of RDF, for example it sets the domain and range of properties and relates the RDF classes and properties into taxonomies using the RDFS vocabulary. Property hierarchy: a property can be a sub-property of another property. RDF Schema ‘semantically extends’ RDF to enable us to talk about classes of resources, and the properties that will be used with them. It is written for the programmer who is unfamiliar with RDF and who learns best by prototyping, or, for other reasons, wishes to move quickly to implementation. RDF data can be encoded with semantic metadata using two syntaxes: RDFS and OWL.

All you need to know is the following 4 principals which form what is known as RDF Schema (RDFS): Class hierarchy: a class can be a sub-class of a parent class. After this tutorial, you should be able to: Understand how RDF data models are semantically encoded using RDFS Overview of RDFS (RDF Schema) within GraphDB, detailing its role in defining the vocabulary and structure of semantic data. Some familiarity with both XML and Java is assumed. .
