Ontologies

Design components

Define class properties

• May be mutually entailing (5.1). Example: "A hasProducer B" ↔ "B hasProduct A".
• Property or class? Choice not obvious.

Define class and general property value constraints

• Value type, including instance.
• Value range (including uniform value).
• Value default (5.2).
• Range of instance-valued property.
• Limits on cardinality.
