The OWL Lite ontology you will create describes Altova products. It consists of the following sections:
| • | Creating a New Ontology: Shows how to create a new ontology document, select an ontology level, and save the ontology document. |
| • | Declaring Namespaces: Explores the Text View and explains what namespaces are required in your ontology document. You will declare namespaces for the AltovaProducts vocabulary and for XML Schema datatypes. |
| • | Creating Classes: Describes how classes are created in RDF/OWL View, and explores RDF/OWL View and Text View. Explains how to delete and re-create classes, and shows how the syntax and semantics of the ontology can be checked in SemanticWorks. |
| • | Creating the Class Hierarchy: Explains how classes are created as subclasses of another class, and thus how a hierarchy of classes can be built. Describes how the Detail View of RDF/OWL View works. |
| • | Defining Properties: Shows how to create OWL properties—both object and datatype—and how to define the domain, range, and cardinality of properties. Also shows how relationships between classes and properties can be viewed in SemanticWorks. |
| • | Declaring Instances: Describes how to create instances, how to define these as instances of a particular class, and how to assign a literal value to an instance. Concludes by showing how created instances can be viewed in the Classes Overview. |
| • | Declaring AllDifferent Instances: Explains how to collect instances in a group and define each of them as being pairwise different from all other members of the group. |
The OWL Lite ontology that is the end result of this tutorial part is delivered in the SemanticWorks package as the file AltovaProducts.rdf; it is located in the application folder: C:/Documents and Settings/<username>/My Documents/Altova/SemanticWorks2008/SemanticWorksExamples/Tutorial.
