NAME

SemanticWeb::Schema::StatisticalPopulation - A StatisticalPopulation is a set of instances of a certain given type that satisfy some set of constraints

VERSION

version v14.0.0

DESCRIPTION

A StatisticalPopulation is a set of instances of a certain given type that satisfy some set of constraints. The property [[populationType]] is used to specify the type. Any property that can be used on instances of that type can appear on the statistical population. For example, a SemanticWeb::Schema::StatisticalPopulation representing all SemanticWeb::Schema::Persons with a [[homeLocation]] of East Podunk California, would be described by applying the appropriate [[homeLocation]] and [[populationType]] properties to a SemanticWeb::Schema::StatisticalPopulation item that stands for that set of people. The properties [[numConstraints]] and [[constrainingProperty]] are used to specify which of the populations properties are used to specify the population. Note that the sense of "population" used here is the general sense of a statistical population, and does not imply that the population consists of people. For example, a [[populationType]] of SemanticWeb::Schema::Event or SemanticWeb::Schema::NewsArticle could be used. See also SemanticWeb::Schema::Observation, and the data and datasets overview for more details.

ATTRIBUTES

constraining_property

constrainingProperty

Indicates a property used as a constraint to define a SemanticWeb::Schema::StatisticalPopulation with respect to the set of entities corresponding to an indicated type (via [[populationType]]).

A constraining_property should be one of the following types:

InstanceOf['SemanticWeb::Schema::Integer']

_has_constraining_property

A predicate for the "constraining_property" attribute.

num_constraints

numConstraints

Indicates the number of constraints (not counting [[populationType]]) defined for a particular SemanticWeb::Schema::StatisticalPopulation. This helps applications understand if they have access to a sufficiently complete description of a SemanticWeb::Schema::StatisticalPopulation.

A num_constraints should be one of the following types:

InstanceOf['SemanticWeb::Schema::Integer']

_has_num_constraints

A predicate for the "num_constraints" attribute.

population_type

populationType

Indicates the populationType common to all members of a SemanticWeb::Schema::StatisticalPopulation.

A population_type should be one of the following types:

InstanceOf['SemanticWeb::Schema::Class']

_has_population_type

A predicate for the "population_type" attribute.
