| Intent: | An object can have different states for which different restrictions apply. The goal of the pattern is to allow modelling the different states of an object and the restrictions on such object for its different states. |
| Domains: | |

|
| Solution description: | The pattern contains three classes, one for representing objects, another for representing object states, and a third one for representing sets of states. Besides, it contains object properties for relating objects and states (which are subproperties of those defined in the Situation pattern [[1]]) and for relating states and sets of states (reused from the CollectionEntity pattern [[2]]) and a datatype property for defining the size of a set of states (reused from the Set pattern [[3]]).
For applying the pattern, first all the possible states of the object must be created as instances of the state class using the Value Partition pattern [4]. Then, different classes must be defined to represent the object in each of the states and state-specific restrictions must be applied to those classes; the object class must be defined as a disjoint union of these classes. |
| Reusable OWL Building Block: | 1 (491) |
| Consequences: | The pattern requires modelling states as individuals instead of as literals. |
| Scenarios: | A sample scenario is the following. A software defect created in an issue tracker must have a creator and be associated to a certain software product. Once it is checked that the defect is reproducible, it must be assigned to some developer and have a certain priority. However, before checking the defect reproducilibty the defect must not have either asignee or priority. |

The Object with states Content OP locally defines the following ontology elements:
Object (owl:Class) Objects are entities that have different states and that in each state different restrictions on their properties apply.
Object 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 page StateSet (owl:Class) State sets are sets of states (i.e., collections of non-duplicate states).
StateSet page
No scenario is added to this Content OP.
This revision (revision ID 11707) 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)
