Elements

The Parameter Content OP locally defines the following ontology elements:

hasParameter (owl:ObjectProperty) A Concept can have a Parameter that constrains the attributes that a classified Entity can have in a certain Situation, e.g. a 4WheelDriver Role definedIn the ItalianTrafficLaw has a MinimumAge parameter on the Amount 16.

hasParameter page

isParameterFor (owl:ObjectProperty) A Concept can have a Parameter that constrains the attributes that a classified Entity can have in a certain Situation, e.g. a 4WheelDriver Role definedIn the ItalianTrafficLaw has a MinimumAge parameter on the Amount 16.

isParameterFor page

hasParameterDataValue (owl:DatatypeProperty) Parametrizes values from a datatype. For example, a Parameter AgeForDriving hasParameterDataValue 18 on datatype xsd:int, in the Italian traffic code. In this example, AgeForDriving isDefinedIn the Norm ItalianTrafficCodeAgeDriving.

More complex parametrization requires workarounds. E.g. AgeRangeForDrugUsage could parametrize data value: 14 to 50 on the datatype: xsd:int. Since complex datatypes are not allowed in OWL1.0, a solution to this can only work by creating two 'sub-parameters': MinimumAgeRangeForDrugUsage (that hasParameterDataValue 14) and MaximumAgeRangeForDrugUsage (that hasParameterDataValue 50), which are components of the main Parameter AgeRangeForDrugUsage.

Ordering on subparameters can be created by using or specializing the object property 'precedes'.

hasParameterDataValue page

Concept (owl:Class) A concept is a SocialObject, and isDefinedIn a Description .

Once defined, a Concept can be used in other descriptions.

The classifies relation relates concepts to entities at some time

Concept page

Parameter (owl:Class) A Concept that classifies something having a certain value, e.g. 'High' can be said of people taller than 185 cm.

However, in order to formally represent this constraint, we need to add an anonymous type to a parameter instance, using a property that convey the semantics of the parameter, e.g.:

High rdf:type Person and (some hasHeight (Height and (oneOf isTallerThan 185) and (oneOf hasUnitOfMeasure centimeter)))
