Learning objectives
- Create ontology classes and subclass relationships with RDF/OWL vocabulary.
- Define object properties with domain and range.
- Create named individuals and assign them to classes.
- Connect individuals through object properties.
- Distinguish schema statements (T-box) from individual assertions (A-box).
- Export the graph as Turtle.

Synthetic teaching scenario. This page creates and serialises RDF statements; it does not run an OWL reasoner or validate logical consistency.
1 · T-box: Classes
2 · T-box: Object properties
3 · Inspect T-box
Classes, subclass links, and property definitions describe the conceptual vocabulary.
Generated T-box (Turtle)
Waiting for library…
4 · A-box: Individuals
5 · A-box: Relationships
6 · Inspect and export A-box
Generated A-box (Turtle)
Create or extend the model, then export it.
7 · T-box versus A-box
T-box · Schema
Classes, subclass relationships, object properties, domain and range.
A-box · Assertions
Named individuals, their class membership and relationships between individuals.
Scope: This lab constructs RDF/OWL statements. It does not infer class membership, perform automatic classification or check consistency. Those are reserved for a later reasoning exercise.
