Diagram
The Object with states Content OP locally defines the following ontology elements:
property1 (owl:ObjectProperty) This property can be used to describe an object.
This is a sample property, when instantiating the pattern it must be renamed with a meaningful name.
property1 page property2 (owl:ObjectProperty) This property can be used to describe an object.
This is a sample property, when instantiating the pattern it must be renamed with a meaningful name.
property2 page property3 (owl:ObjectProperty) This property can be used to describe an object.
This is a sample property, when instantiating the pattern it must be renamed with a meaningful name.
property3 page
Object (owl:Class) Objects are entities that have different states and that in each state different restrictions on their properties apply.
Object page ObjectStateA (owl:Class) This class represents those objects that are in certain state.
This is a sample class, when instantiating the pattern it must be renamed with a meaningful name.
ObjectStateA page ObjectStateB (owl:Class) This class represents those objects that are in certain state.
This is a sample class, when instantiating the pattern it must be renamed with a meaningful name.
ObjectStateB page ObjectStateC (owl:Class) This class represents those objects that are in certain state.
This is a sample class, when instantiating the pattern it must be renamed with a meaningful name.
ObjectStateC page State (owl:Class) States are the different states that an object can have. States must belong to a single collection of non-duplicate elements (i.e., to a set).
State pageThis is a sample instance, when instantiating the pattern it must be renamed with a meaningful name.
StateA pageThis is a sample instance, when instantiating the pattern it must be renamed with a meaningful name.
StateB pageThis is a sample instance, when instantiating the pattern it must be renamed with a meaningful name.
StateC pageOntology including the content ontology design pattern for modelling objects with states.
No scenario is added to this Content OP.
This revision (revision ID 11697) takes in account the reviews: Object with states (AlessandroAdamou about Object with states, RinkeHoekstra about Object with states, BenedictoRodriguezCastro about Object with states, BenedictoRodriguezCastro about Object with states 2)
